Salah satu respons fisiologis tanaman terhadap kekurangan air adalah penurunan konsentrasi klorofil daun yang dapat disebabkan oleh pembentukan klorofil dihambat, penurunan enzim rubisco, dan terhambatnya penyerapan unsur hara, terutama nitrogen dan magnesium yang berperan penting dalam sintesis klorofil. Kandungan klorofil daun dapat dipakai sebagai indikator yang terpercaya untuk mengevaluasi ketidakseimbangan metabolisme antara fotosintesis dan hasil produksi pada saat kekurangan air. Kata kunci: cekaman, fotosintesis, respons fisiologi THE CONCENTRATION OF LEAF CHLOROPHYLL AS WATER-DEFICIT INDICATOR IN PLANTS ABSTRACT Water deficit influences all aspects of plant growth including physiological, biochemical, anatomical and morphological processes. One of plant physiological responses to water deficit is the decrease of leaf-chlorophyll concentration because the chlorophyll synthesis is inhibited, the rubisco enzyme was reduced and the absorption of nutrients, especially nitrogen and magnesium that are required for chlorophyll synthesis, was inhibited. The concentration of leaf chlorophyll is able to be used as reliable indicator for evaluating unbalanced metabolism between photosynthesis and plant production under water deficit.

The present study shows that rhizosphere microbes play an important role in increasing the availability of water-soluble Zn in soil, thus enhancing Zn accumulation by T. caerulescens. The addition of bacteria to surface-sterilized seeds of T. caerulescens sown in autoclaved soil increased the Zn concentration in shoots 2-fold as compared to axenic controls; the total accumulation of Zn was enhanced 4-fold. When the same experiment was conducted with Thlaspi arvense, a nonaccumulator, bacteria had no effect on shoot Zn accumulation although they increased water-soluble Zn concentrations available to both Thlaspi species by 22−67% as compared to the axenic controls. Further evidence that bacteria increase the availability of water-soluble Zn in soil was obtained when liquid media that had supported bacterial growth mobilized 1.3−1.8-fold more Zn from soil as compared to axenic media. Other experiments with agar media showed that bacteria did not facilitate an increase in the rate of soluble Zn transport into the root nor did they enlarge the surface area of the roots of either Thlaspi species. Thus, the bacterially mediated increase in the dissolution of Zn from the nonlabile phase in soil may enhance Zn accumulation in T. caerulescens shoots.

In plant tissue culture, growth regulator has significant roles such as to control root and shoot development … The Role of Growth Regulator in Tissue Culture Plant Propagation. Endang G. Lestari. In plant tissue culture, growth regulator has significant roles such as to control root and shoot development in the plant formation and callus induction. Cytokinin and auxin are two prominent growth regulator. Cytokinin consists of BA (benzil adenin), kinetin (furfuril amino purin), 2-Ip (dimethyl allyl amino purin), and zeatin. While auksin covers IAA (indone acetic acid), NAA (napthalene acetic acid), IBA (indole butiric acid) 2.4-D (2.4- dicholophenoxy acetic acid), dicamba (3,6 dicloro-O-anisic acid), and picloram (4-amino 3,5,6-tricloropicolinic acid). The emphasis of plant growth purposes decide the use of growth regulator. Cytokinin is applied mainly for the purpose of shoot, while auxin is mainly used for the purpose of root and callus. The application of growth regulator application is varied, depending on the genotype and physiological condition of the plant. The existence of a certain growth regulating substances can enhance growth regulator activity of other substances. The type and concentration of the appropriate growth regulators for each plant is not the same because it depends on the genotype and physiological condition of plant tissue. However so often both are frequently required depend on the ratio/ratio of auxin cytokines or vice versa. The existence of a certain growth regulating substances can enhance growth regulator activity of other substances. The type and concentration of the appropriate growth regulators for each plant is not the same because it depends on the genotype and physiological condition of plant tissue. For the propagation, multiple and adventive shoots along with embriosomatic formation could be applied. The seedling is obtained from one somatic cell. Here, strong auxin, such as dicamba and picloram 2.4-D, is utilized for callus production. For this reason, seedling per unit could be produced more than that of organogenesis.

Kualitas dan komposisi pupuk organik bervariasi tergantung dari bahan dasar kompos dan proses pembuatannya. Penggunaan tanaman legum baik berupa tanaman lorong (alley cropping) maupun tanaman penutup tanah (cover crop) serta bahan organik insitu, perlu diintensifkan untuk mendukung pemanfaatan pupuk organik non komersial dan pemulihan kesuburan tanah.Pemberdayaan masyarakat dan kelompok tani dalam pengadaan pupuk organik dapat dilakukan melalui: a) melatih petani membuat pupuk organik insitu yang berasal dari kotoran ternak dan sisa tanaman yang dikomposkan;b) mendorong petani melakukan diversifikasi usaha pertanian berbasis ternak; dan c) mendorong petani melakukan pengelolaan bahan organik insitu terutama pada lahan kering. Pemanfaatan pupuk organik telah diterapkan dalam sistem budidaya pertanian organik (organic farming) dan System rice of intensification (SRI). Pemberian pupuk organik yang dikombinasikan dengan pupuk anorganik, telah diterapkan dalam sistem pengelolaan tanaman terpadu (PTT), sistem integrasi padi/palawija dan ternak (SIPT), sistem pertanian mandiri yang mengintegrasikan ternak dan tanaman crop livestock system (CLS). Abstract: It is inevitable that organic fertilizer plays a major role in increasing the fertility of the physical, chemical and biological as well as the efficient use of inorganic fertilizers. The main composition of organic fertilizer when it decomposes will consist of mostly water and cellulose, hemiselulose, lignin, and a small portion main macro nutrients, secondary macro nutrients, micro elements and silica. There is also a growth regulating enzymes and vitamins as a byproduct of microbial decomposition. The main component or specific parameters have a major role and the speed of the process of transformation of organic fertilizer into the form of mineral nutrients and the end product is humus. The significance of organic fertilizer is widely recognized by agricultural researchers and practitioners. In addition the use of organic fertilizers in paddy fields and dry land cultivation system of agriculture that combines inorganic fertilizer and organic, has strived implemented by the government in this case the Ministry of Agriculture that the system of integrated crop management (ICM), system integration paddy/crops and livestock (SIPT), an independent agricultural systems that integrate livestock and crop plants livestock system (CLS). If the awareness of farmers on the use of organic fertilizers increases, the availability of both in situ and have to come from outside should be available in sufficient quantity and good quality. Technological innovation of Agricultural Research and Development Agency to support the use of organic fertilizers continue to research and develop. Currently available guidebooks and technological innovation, such as land management guidelines, management guidelines of organic materials and organic fertilizer, granular organic fertilizer product (Tithoganik, POG, POCr), and decomposers products to accelerate the process of decomposition (such as M-dec). Opportunities and challenges in increasing stakeholder awareness is not a barrier in optimizing organic fertilizer. The key is the synergistic integration between institutions regulatory, technical institutions, Research Agency, producers and users in the implementation of socialization, production, guidance and supervision.

The studied population consisted of 200 farmers who implemented mung bean extension after rice production and registered with the Department of Agricultural Extension in the crop year of 2023 and 2024 in Utumpornphisai District, Sisaket Province. Using Taro Yamane’s formula with a 95% confidence level, the sample size was determined to be 134 farmers. For simple random sampling, data collection was conducted through interviews, and data were analyzed using frequency, percentage, mean, standard deviation, and multiple regression analysis. The results indicated the followings: 1) The farmers had a high level of extension needs for mung bean cultivation in 2 areas, namely, individual extension, which requires a visit to their home or farm, and group extension, which requires study tours and conferences. 2) For factors affecting mung bean after rice production for farmers, it was found that there were no independent variables with a statistically significant relationship at the 0.05 levels. This means that difference in age, education level, experience in growing mung beans, experience in training, household labor, rice growing area, mung beans planting area behind rice fields, cost of growing mung beans, and average income from growing mung beans did not affect farmers growing mung beans behind their rice fields and 3) The farmes had problems at a high level regarding knowledge about mung bean varieties and post-harvest technology. They also suggested that there should be a group of mung bean growers and a learning plot arranged as a learning center to demonstrate and view the work of the farmers in the area.

Jernang ini menghasilkan resin merah dari buahnya yang digunakan sebagai pewarna alami untuk kerajinan rotan serta dalam pengobatan tradisional, seperti obat luka, sakit kepala, dan pilis pasca melahirkan. Keunggulan C. acehensis dibandingkan jenis jernang lainnya terletak pada pertumbuhan yang cepat dan produksi resin yang tinggi pada usia muda. Pada usia dua tahun, tanaman ini sudah mencapai tinggi dua meter dan mulai berbuah. Ciri morfologi khas meliputi ruas batang hingga 50 cm, panjang daun sampai 2 meter, tangkai daun 35 cm, serta selubung daun berwarna hitam dengan duri panjang dan padat. Penelitian ini bertujuan mengkaji morfologi polen untuk menentukan sistem penyerbukan dan status taksonominya. Sampel polen diambil dari C. acehensis yang tumbuh di Desa Rieseh Tengoh, Aceh dan dari budidaya di Jambi. Analisis dilakukan menggunakan Scanning Electron Microscope (SEM) di Laboratorium Penelitian dan Pengujian Terpadu UGM. Hasil menunjukkan bahwa kedua sampel memiliki ukuran polen kecil, yaitu 1,212 µm (Aceh) dan 1,116 µm (Jambi), dengan bentuk aperture monocolpate tunggal dan ornamentasi eksin rata. Karakteristik ini menunjukkan potensi penyerbukan silang (xenogami) yang dibantu angin (anemogami), memberikan wawasan penting untuk konservasi dan budidaya jernang Aceh.

Data collection was carried out during … This study aims to analyze the relationship between water depth and rice yields in tidal swamps in Melayu Ilir Village, Banjar Regency, South Kalimantan. Data collection was carried out during one planting season with periodic measurements of water depth and rice yields in tons/ha. The analysis was carried out using linear and polynomial regression to determine the best statistical model that represents the relationship between water depth and plant productivity. The results showed that the relationship between water depth and yields was negative and non-linear, with a third-order polynomial model as the best model (R² = 0.995). The optimal water depth to achieve maximum yields is in the range of 10–20 cm. Increasing water depth above 30 cm tends to cause a significant decrease in yields. This study provides a scientific basis for precise and sustainable irrigation management in swamps

This study investigated the effects of goat manure and liquid organic fertilizer (POC) from tofu wastewater on okra growth and yield in alluvial soil. A completely randomized factorial design was employed with two factors: goat manure doses (50, 100, 150 g/polybag) and tofu wastewater POC concentrations (10%, 20%, 30%), each replicated three times, resulting in 27 experimental units. Soil analysis revealed significant improvements in chemical and physical properties after treatment application. Initial soil pH increased from 4.82 to 5.9, organic carbon content rose from 1.82% to 3.05%, total nitrogen increased from 0.16% to 0.42%, and available phosphorus improved from 18.3 ppm to 92.14 ppm. Physical properties also enhanced with bulk density decreasing from 1.62 to 1.24 g/cm³ and total porosity increasing from 34.21% to 46.37%. ANOVA analysis showed significant effects of POC concentration on plant height and fruit weight, with 20% concentration producing optimal results. Goat manure significantly influenced fruit weight, with the highest dose (150 g/polybag) yielding 89.44 g compared to 56.96 g at the lowest dose. No significant interactions were observed between the two factors. The results demonstrate that combined application of goat manure and tofu wastewater POC effectively transforms degraded alluvial soil into fertile growing medium, supporting sustainable okra production in marginal lands.

The total biomass in the area amounts to 172.031 tons/ha, with a carbon storage capacity of 80.855 tons/ha and CO2 capture of 296.738 tons/ha. The sapling stratum, characterized by greater mangrove density, produces higher biomass and accommodates more carbon reserves compared to the mature tree stratum. Avicennia marina is identified as the most significant contributor to biomass, carbon storage, and CO2 absorption. Mangroves, through their dense root systems and photosynthetic processes, trap and store carbon both in their biomass and in waterlogged sediments, where decomposition is slowed. Additionally, tidal exchanges enhance carbon capture by promoting the deposition of organic material, further increasing carbon storage in coastal areas. These ecosystems play a crucial role in mitigating climate change by sequestering large amounts of carbon, protecting coastal habitats, and supporting biodiversity, emphasizing the need for their conservation in climate action strategies.

This study aims to investigate the impact of Trichoderma on tomato growth and the progression of Fusarium wilt disease infection. The method used was the Complete Randomized Design (CRD) method. Data from the observation of the intensity of Fusarium wilt disease attack on tomato plants with treatments (P1, P2, P3, P4, P5) showed no significant differences. The treatment of Trichoderma on plant height, number of leaves, number of flowers, number of fruits, and intensity of attack did not have a significant effect in suppressing the development of Fusarium wilt disease infection in tomato plants. Trichoderma application treatment that had the highest effect on tomato plant growth was found in treatment P4 (tomato seedlings soaked for 25 minutes using Trichoderma). The treatment with the lowest intensity of Fusarium wilt attack was found in treatment P5 (Trichoderma incubation in the soil 10 days before planting), showing a better reduction in wilt intensity compared to other treatments.

However, the content of songs sung is often not given much attention. Through this concern, the author will carry out expositional exegesis of three examples of Gospel-centered songs. First, the song of Moses and the Israelites from Exodus 15:1-21, which shows that the song emerged because the Israelites had seen concrete evidence of what God had done in their lives, namely saving and freeing them from slavery and long suffering. Second, Mary's song from Luke 1:46-56, which was raised out of great gratitude for the miraculous work of God's grace in the lowly personal life of Mary and her sinful nation. Third, the song of the Lamb from Revelation 4:8-11 and 5:8-14, which is a song that expresses the majesty of God, the Creator and the Redeemer. Through this research, it’s hoped that it can equip church leaders regarding Gospel-centered songs and their significance. Abstrak: Nyanyian rohani yang berdasarkan narasi Injil adalah nyanyian yang baik dan “sehat” bagi jemaat karena nyanyian rohani yang bernarasi Injil memiliki signifikansi sebagai nyanyian yang mengekspresikan iman dan relasi orang percaya kepada Allah, yang meliputi identitas dan pekerjaan Allah, serta memformasi identitas dan makna hidup orang percaya. Penulis akan melakukan eksegesis eksposisional dari tiga contoh nyanyian rohani bernarasi Injil dalam Alkitab. Pertama, nyanyian Musa dan bangsa Israel dari Keluaran 15:1-21, yang menunjukkan nyanyian muncul karena bangsa Israel telah melihat bukti nyata apa yang Allah telah lakukan dalam kehidupan mereka, yaitu menyelamatkan dan membebaskan mereka dari perbudakan dan penderitaan yang begitu panjang. Kedua, nyanyian Maria dari Lukas 1:46-56, yang dinaikkan dari rasa syukur yang besar atas karya anugerah Allah yang ajaib dalam kehidupan pribadi Maria yang rendah dan bangsanya yang berdosa. Ketiga, nyanyian Anak Domba dari Wahyu 4:8-11 dan 5:8-14, yang merupakan sebuah nyanyian yang mengungkapkan keagungan Allah, Sang Pencipta dan Sang Penebus. Melalui penelitian ini, diharapkan dapat memperlengkapi para pemimpin gereja mengenai nyanyian rohani bernarasi Injil dan signifikansinya.

Wilczek), yakni varietas lokal Gronong, Vima-3, dan Vima-4, yang dibudidayakan di Kabupaten Grobogan sebagai salah satu sentra produksi utama di Jawa Tengah. Karakterisasi ini dilakukan berdasarkan parameter morfologi kualitatif yang mencakup struktur batang, daun, bunga, polong, dan biji. Pengamatan dilakukan secara deskriptif, kemudian dianalisis menggunakan pendekatan dendogram untuk mengevaluasi tingkat kekerabatan genetik antar varietas. Hasil penelitian menunjukkan bahwa terdapat diferensiasi morfologis yang signifikan, terutama pada warna hipokotil, keberadaan antosianin, bentuk dan warna polong, serta bentuk biji. Varietas lokal Gronong menunjukkan karakteristik unik berupa kandungan antosianin yang tampak jelas pada hipokotil dan tangkai daun yang membedakannya secara konsisten dari varietas Vima-3 dan Vima-4 yang tidak mengandung antosianin. Analisis dendogram mengelompokkan varietas Vima-3 dan Vima-4 dalam satu klaster dengan tingkat kemiripan 60-70%, sedangkan varietas lokal Gronong membentuk klaster tersendiri dengan kemiripan hanya 10-20%. Keberagaman ini menandakan bahwa varietas lokal Gronong memiliki potensi tinggi sebagai sumber genetik untuk program pemuliaan tanaman dan konservasi plasma nutfah lokal, sekaligus referensi dalam pemilihan varietas unggul adaptif terhadap ekosistem spesifik di wilayah tropis. Penelitian ini diharapkan dapat menjadi acuan dalam pemilihan varietas kacang hijau yang sesuai dengan kondisi agroekosistem setempat khususnya di wilayah Kabupaten Grobogan yang menjadi sentra produksi dan budidaya kacang hijau.Kata kunci: Kacang Hijau, Karakterisasi, Morfologi, Varietas Lokal

Ketika diserahkan kepada Sultan Agung dari Mataram, namanya diubah menjadi Priangan. Selanjutnya sesudah jatuh ke tangan Pemerintah Hindia Belanda Gubernur Jenderal H.W. Daendels pada tahun 1808 menetapkan Priangan menjadi Prefectuur Preanger-Regentschappen dan pada masa pemerintahan Inggris (1811-1816), Thomas Stamford Raffles, diganti menjadi Keresidenan Priangan, yang terdiri atas lima kabupaten yaitu; Bandung, Cianjur, Sumedang, Limbangan, dan Sukapura. Pemerintahan di setiap kabupaten dijalankan oleh kelompok aristokrasi lokal di bawah pengawasan penjajah. Kelompok aristokrasi lokal, yang disebut kaum ménak ini, terdiri atas para bupati, bawahan bupati, dan sanak kerabat mereka. Kaum menak memiliki gaya hidup (style of life) tersendiri, termasuk memiliki tempat tinggal khusus yang membedakan mereka dengan rakyat kecil. Dalam tulisan ini secara khusus akan diuraikan tentang tempat tinggal kaum menak di Priangan, sejak 1800 hingga 1942. Berbagai informasi yang beragam itu dikoroborasikan untuk menghasilkan suatu rekontruksi tentang tempat tinggal kaum menak di Priangan. Untuk itu dilakukan penelitian menggunakan metode sejarah yang terdiri atas empat tahap yaitu heuristik, kritik, interpretasi dan historiografi. Untuk memberikan eksplanasi tentang tempat tinggal kaum menak diperlukan pendekatan yang bersifat multidimensi, selain pendekatan historis juga dilakukan pendekatan filologis, antropologis dan sosiologis.Tempat tinggal kaum menak semula bergaya aristektur seperti keraton dengan pendopo di depannya. Selanjutnya karena pengaruh Eropa, gaya arsitektur itu bercampur dengan gaya barat dan lebih dikenal sebagai regent-woning (rumah bupati) dengan perabotan yang bergaya keraton.

However, melon production in Plintahan … Plintahan Village is one of the villages in Pandaan District, Pasuruan Regency, East Java that has the potential for developing melon (Cucumis melo L.) cultivation. However, melon production in Plintahan Village is still relatively low due to the lack of farmer knowledge about melon cultivation and the high level of pest and disease attacks due to uncontrolled environmental factors. Efforts that can be made to optimize land through melon cultivation are by developing melon cultivation in screenhouses, applying natural Plant Growth Regulators (PGRs) with shallot extract, bamboo shoots, and coconut water, and providing KNO3 fertilizer. The growth parameters observed were plant height and number of leaves. Based on these parameter data, a plant growth model was then made. The results of the study showed that the use of natural PGRs from a mixture of bamboo shoots, coconut water, shallots, and KNO3 fertilizer affected the height and number of leaves on melon plants. Cultivation carried out on melon plants in screenhouses provides benefits for the yield and growth of melon plants, namely preventing pest and disease attacks, and reducing the effects of environmental stress. Melon cultivation in screenhouses with the application of natural PGRs and KNO3 fertilizer can be one effort in optimizing land.

Mesin penggiling jagung yang digunakan dilengkapi dengan motor … Penelitian ini bertujuan untuk meneliti mengenai pengaruh variasi jumlah mata pisau, kecepatan putaran mesin, dan ukuran saringan terhadap kinerja mesin penggiling jagung. Mesin penggiling jagung yang digunakan dilengkapi dengan motor gerinda dan dilengkapi dengan tiga variasi jumlah mata pisau (2, 3, dan 4 bilah), dua kecepatan putaran mesin (50% dan 100%), serta dua ukuran saringan (3 mm dan 6 mm). Pengujian dilakukan untuk mengukur kapasitas produksi dan kecepatan penggilingan berdasarkan kombinasi tersebut. Hasil penelitian menunjukkan bahwa kombinasi jumlah mata pisau dan kecepatan putaran berpengaruh signifikan terhadap waktu penggilingan. Penggunaan 2 bilah mata pisau dengan kecepatan putaran 100% pada saringan 6 mm menghasilkan waktu penggilingan tercepat, yaitu 14,93 detik. Sementara itu, peningkatan jumlah mata pisau justru mengurangi efisiensi produksi, terutama pada kecepatan putaran yang lebih tinggi. Selain itu, saringan berukuran 6 mm cenderung menghasilkan kapasitas produksi yang lebih besar dibandingkan dengan saringan 3 mm. Dari penelitian ini dapat disimpulkan bahwa untuk mencapai efisiensi maksimal dalam penggilingan jagung, kombinasi yang paling optimal adalah penggunaan 2 bilah mata pisau, kecepatan putaran 100%, dan saringan 6 mm. Hasil ini menunjukkan bahwa mesin penggiling jagung yang diuji mampu memberikan hasil yang stabil dan dapat diandalkan dengan variasi parameter yang berbeda.

It can cause symptoms like fever and salivary gland swelling. Despite the MMR vaccine, which offers partial protection, outbreaks persist, especially in college-aged individuals. Epidemiological models can aid in identifying effective prevention strategies for controlling mumps transmission. This paper proposes a mathematical model for mumps spread, considering quarantined individuals and complications. A global stability analysis of the mumps transmission model was performed, considering mortality and quarantine subpopulation. The Disease Free Equilibrium and Endemic Equilibrium Point are globally stable, confirmed by Lyapunov functions. Sensitivity analysis of the basic reproduction number shows that reducing birth rates and contact between infected and susceptible individuals effectively minimizes the infected population. However, increasing the natural death rate can reduce the total population, which may lower infections, but poses potential social and economic challenges for decision-makers.

One … Nutmeg has considerable potential to enhance the local economy, especially in the Papua region, where it is primarily cultivated in the Fakfak Regency and commonly known as Fakfak Nutmeg. One of the major challenges in nutmeg cultivation is the extended seed germination period, which limits the availability of high-quality planting materials. Typically, untreated nutmeg seeds germinate within 2 to 3 months after planting, whereas scarified seeds germinate more quickly, in approximately 1.5 months. This study aimed to evaluate the effects of different growth media and seed coat scarification on nutmeg seed germination. A randomized factorial design was employed, with seed coat treatment and growth medium. The observed variables included germination percentage, germination rate, peak value, average daily germination, seedling height, number of leaves, number of roots, and stem weight. The results showed that scarification had a significant effect on germination, particularly in terms of germination percentage, average daily germination, germination rate, and peak value. However, it did not significantly affect other growth parameters such as seedling height, number of leaves, number of roots, or stem weight. No significant differences in germination performance were observed between sand and soil media.

Weeds are one of the major challenges in agricultural cultivation systems, as they can reduce crop productivity. One strategy to enhance the production of secondary metabolites in sorghum plants is the application of abiotic stress, such as drought. This approach not only has the potential to produce high-quality extracts but also supports the development of effective bioherbicides. This study aims to analyze the effects of drought stress on flavonoid content and the allelopathic properties of sorghum. The research was conducted from June to August 2024 in the Greenhouse of Bengkulu University, with bioassay tests performed in Pematang Gubernur, Muara Bangkahulu, Bengkulu City. The study employed a single-factor completely randomized design (CRD) using two sorghum varieties, Super 1 and Suri 4. The drought stress treatments included three levels of watering frequency: daily, once every three days, and once every five days. The bioassay was conducted using the petri dish method, where each petri dish was treated with 10 mL of sorghum aqueous extract, 25 mung bean seeds were sown, and incubation was carried out for three days. The results showed that the highest total flavonoid content was found in the Super 1 variety with watering every five days (4067.01 µg/g), while the lowest was observed in the Suri 4 variety with daily watering (2948.07 µg/g). The highest seed germination inhibition was recorded in both Suri 4 and Super 1 varieties under the five-day watering interval. These findings indicate that the Super 1 and Suri 4 sorghum varieties subjected to drought stress can serve as potential bioherbicide sources for sustainable weed management.

However, cayenne pepper productivity in Indonesia … Cayenne peppers (Capsicum annuum L.) are horticultural commodities with high economic value and increasing market demand, both for household consumption and large-scale processing industries. However, cayenne pepper productivity in Indonesia remains relatively low, partly due to the limited availability of fertile land. One potential solution to this problem is the utilization of marginal lands, including ultisols. Ultisols possess chemical characteristics that are less favorable for optimal plant growth, such as low pH, poor nutrient content, and high aluminum saturation. There fore, this study aimed to obtain information on cayenne pepper genotypes that can adapt well and produce optimally on ultisols. The research was conducted at the Experimental Garden of the Faculty of Agriculture, University of Bengkulu, from May to October 2023, using a Randomized Complete Block Design (RCBD) with three replications. Observed parameters included plant height, first dichotomous height, stem diameter, number of dichotomous points, total leaf area, shoot dry weight, stomatal density, days to first harvest, number of fruits per plant, fruit length and diameter, fruit weight per plant, and percentage of marketable fruits. Data were analyzed using ANOVA at a 5% significance level and followed by Duncan’s Multiple Range Test (DMRT) at the same level. The results indicated significant differences among genotypes in most growth and yield parameters. The genotypes ‘Iggo’ and ‘Lajang’ exhibited superior performance, with the highest dry biomass weight and the highest fruit weight per plant. These findings suggest that the ‘Iggo’ and ‘Lajang’ genotypes hold strong potential for cultivation on Ultisol soils to support sustainable national cayenne peppers production improvement.

The crop is a stress-resilient crop with highly productive NADP-ME type C4 photosynthesis and highly efficient nitrogen and water utilization. Sorghum also requires relatively less water than other important cereals such as maize and wheat. Sorghum cultivation is very suitable to be carried out in Sumbawa Regency because it has the characteristic of low rainfall. The most common obstacle that occurs in sorghum cultivation is not being able to maximize plant genetics and existing nutrients, so that plant yields are low. One of them is by applying organic fertilizer. The interest in the use of organic fertilizers is increasing due to polluting effects of chemical fertilizers in the aerial and soil environment and gradual decline in the soil fertility. The aim of this study was to determine the yield of plants with different doses of organic fertilizers and sorghum varieties in Sumbawa Regency. This research used Split Plot Design consisting of two plots. The main plot three sorghum varieties were evaluated including V1 = Bioguma, V2 = GBE Methane, and V3 = Sweetbetty. The subplot is the application of solid organic fertilizer including T0 = control, T1 = 50 g plant-1, T2 = 100 g plant-1, and T3 = 200 g plant-1. This study had 3 replications and 36 experimental units. The results show that organic fertilizer application doses can cause significant differences in root weight, dry weight, fresh weight, grain weight/plant, weight 1000 grains, productivity, panicle length, and flowering age. Then, different types of sorghum also cause significant differences in grain weight per plant, weight of 1000 grains, and productivity. The best productivity is found at 200 g plant-1 of organic fertilizer. Optimal fertilizer application produces better grain.

During floods, water transports various materials from upstream to downstream, such as sand, mud, and clay, which are deposited in certain riverbanks. This study aimed to examine the soil fertility characteristics in the floodplain area. The method used in this research was a survey method with purposive random sampling at two soil depths: 0 – 30 cm and 30 – 60 cm. Samples were taken from two land uses: dryland agriculture and wetland agriculture. The parameters analyzed were texture, organic carbon, bulk density, total pore space, pH in H2O, available P, total N, and exchangeable potassium. The results of the study for each parameter showed that the soil texture in dryland agriculture was sandy loam, while in wetland agriculture, it was clay loam. Organic carbon was classified as low (1.31%–1.62%). Wetland soils had higher porosity (57.67%–61.40%) and lower bulk density (1.01–1.10 g/cm³) compared to dryland soils. Soil pH was acidic (4.52–4.95). Available P, total N, and exchangeable potassium were higher in wetland soils than in dryland soils. In conclusion, the results of the study indicate that the soil properties, both physical and chemical, in wetland agriculture were better than in dryland agriculture, although no significant differences were found.
