Sorghum Allelochemistry and Its Use as a Bioherbicide: A Comprehensive Review

2026-02-08T14:47:54+00:00

Sorghum bicolor is a potential plant source for bioherbicide phytochemicals via allelopathy. Allelochemicals from sorghum plants and phenolic compounds have repelled and inhibited the growth and germination of weed seeds during several rounds of pulling and burning. This study compiled the latest literature to understand phenolic allelochemicals regarding the potential for sustainable weed management. This review shows that sorghum bioherbicidal phytochemicals have the potential to inhibit weed germination and growth by physiologically and biochemically altering weed physiology and biochemistry, including inhibition of photosynthesis via membrane destruction. Disruption of growth-regulating hormones, the formation of oxidative stress characterized by increased lipid peroxidation, and the induction of cell membranes. This is determined by external environmental factors, soil microbial dynamics, the cultivar genotype, and variations in the methods used to extract and apply them. In addition to root exudates and residues, sorghum intercropping has been shown to promote soil health and enhance weed suppression. Sorghum intercropping in sustainable systems offers an environmentally friendly alternative to synthetic herbicides. This offers a path for future field research on bioherbicide formulations to investigate safe concentration thresholds and the phytochemicals that are only partially stable in the field. Overall, sorghum has broad potential for intercropping systems, sustainable agriculture, and efficient, adaptive weed management.

2026-02-09T03:00:57+00:00

Chili pepper (Capsicum annuum L.) is a high economic value horticultural commodity that requires optimal nutrient availability to support vegetative growth and fruit formation. Fertilization is a key factor in increasing chili productivity, both through the use of inorganic fertilizers such as NPK and liquid organic fertilizer (LOF). This literature review discusses the role and effectiveness of LOF and NPK application on the growth and yield of chili plants. The review findings show that NPK supplies the primary macronutrients nitrogen, phosphorus, and potassium, which function in chlorophyll formation, root development, flowering, and increased fruit production. LOF contributes to improving soil properties, enhancing microbial activity, and supplying micronutrients. The combination of LOF and NPK is considered more effective than single use because it increases nutrient uptake efficiency and supports sustainable agriculture. However, further research is needed regarding LOF quality standards and the optimum dosage of the combination for chili cultivation.

Soybean yields in Rokan Hulu continue to increase along with the increasing population and the increasing diversity of basic soybean growth, the increasing demand for soybeans is not accompanied by growth by Rokan Hulu farmers, this is due to the decreasing area of land that can be planted with soybeans and low soil fertility, so efforts need to be made towards the growth and yield of soybeans, it is hoped that the use of organic mulch of alang-alang can increase soybean yields. This study was conducted to determine the effect of giving several doses of organic mulch of alang-alang on the growth and yield of soybeans. This study used a Randomized Block Design (RAK) with 5 treatments, each treatment had 4 groups of plants, where each plot consisted of 10 plants. The treatments are P0 = without organic mulch of cogongrass, P1 = organic mulch of cogongrass 5.6 kg, P2 = organic mulch of cogongrass 7.2 kg, P3 = organic mulch of cogongrass 8.8 kg, P4 = organic mulch of cogongrass 10.4 kg. The variables observed were plant height, leaf width, number of plants, flowering age, harvest age, number of filled pods, wet seed weight, dry seed weight, weight of 100 seeds. The results of this study were seen from the results of the Duncan multiple distance test (DMRT a 5%). The provision of organic mulch of cogongrass on soybean plants had a significant effect on harvest age, flowering age, number of filled pods, wet seed weight, dry seed weight, weight of 100 seeds and had no significant effect on plant height, leaf width, number of leaves. This is due to the suboptimal nutrients given to the soil. The provision of organic mulch of alang-alang grass with a dose of 8.8 kg tends to affect the growth and yield of soybean plants.

Sweet Corn (Zea mays saccaratha Sturt) is in great demand because of its nutritional and economic value. Sweet corn consumption is increasing in Indonesia, but the industry faces challenges such as pests, disease and access to fertilizer. Using sugarcane bagasse as compost can increase soil fertility and reduce waste. This research aims to determine the effect of the dose of bagasse compost on the growth and yield of sweet corn. This research used a Randomized Block Design (RAK) with 5 actions, namely P0 : without adding bagasse compost (control), P1: 20 tons/ha of bagasse compost equivalent to 1.96 kg/plot, P2 : 25 tons/ha of bagasse compost equivalent to 2.45 kg/plot, P3: 30 tons/ha of bagasse compost equivalent to 2.94 kg/plot, P4: 35 tons/ha of bagasse compost equivalent to 3.43 kg/plot Each treatment was repeated four times in groups. The variables observed were plant height, leaf length, leaf width, cobs length, cobs diameter and cobs weight. The results of data analysis are analyzed using variance analysis, if the results of variance analysis show a real difference, then proceed with a further significant difference test (DMRT 5%). The results of the research showed that the provision of bagasse compost did not have a real effect on any observed variables. The absence of real differences in all observed variables is thought to be caused by the dosage of bagasse compost not having reached the right level to support optimal growth in sweet corn plants.

This study aims to analyze the marketing channels and calculate the costs, margins, and profits of green bean robusta coffee marketing in Sumber Sari Village, Kabawetan District, Kepahiang Regency. Robusta coffee is a plantation commodity with high economic value and plays a crucial role in the local economy. This research used a descriptive quantitative method, collecting data through interviews, observation, and documentation involving 20 farmers and 5 coffee collectors. The findings revealed one main marketing channel: from farmers to local collectors and then to other village collectors. This marketing structure is simple and efficient. The average selling price at the farmer level was Rp72,000/kg, while the consumer-level price reached Rp85,000/kg. The total marketing margin was Rp13,000/kg, with a marketing cost of Rp6,000/kg and a net profit of Rp7,000/kg. The farmer’s share reached 85.71%, indicating that farmers still gain a significant portion of the profit. This system’s advantage lies in cost efficiency, as collectors directly collect the harvest from the farmers. Furthermore, farmer characteristics such as productive age, over six years of farming experience, and land ownership between 1–2 hectares contributed to marketing success. It is recommended that farmers improve product quality and strengthen institutions such as cooperatives to enhance bargaining power. With a straightforward distribution system and the active role of collectors, the green bean robusta coffee marketing in Sumber Sari Village is considered effective and profitable.

The Effect Of Coconut Drain Compost Fertilizer On The Growth And Production Of Tomato Plants (Solanum Lycopersicum L.)

2026-01-30T04:43:49+00:00

Tomatoes are a popular fruit and vegetable due to their delicious, fresh, and slightly sour taste. Besides being eaten raw, they can also be processed into various foods such as jam, sauce, and chili sauce. Demand for tomatoes continues to increase year by year. Cultivating tomatoes requires fertilizer. Farmers mostly use chemical fertilizers, potentially leading to land degradation due to excessive chemical use. Coconut pulp is a solid waste product from coconut milk and coconut oil processing. Coconut pulp is often discarded, but it can be used as compost because it contains nutrients that can help improve soil fertility. This study was conducted to determine the growth and production response of tomato plants with the application of coconut pulp compost. This study was conducted at the experimental garden of the Faculty of Agriculture, Pasir Pengaraian University, from December 2024 to March 2025. The method used was a Completely Randomized Design (CRD) with 4 treatments, each consisting of 3 replications, and each plot consisting of 6 plants, each containing 3 sample plants, resulting in a total population of 72 plants. The results showed that the addition of coconut pulp compost significantly affected all observed parameters, namely plant height, leaf number, flowering time, and fruit weight. The best dose obtained was 150 grams per polybag of coconut pulp compost in treatment (P2).

Efektivitas Limbah Lele Pada Tanaman Jagung (Zea Mays ) Elos Sebagai Pakan Ternak

2026-01-31T06:00:53+00:00

Penelitian ini dilatarbelakangi oleh upaya mencari solusi ramah lingkungan dan berkelanjutan dalam meningkatkan produksi tanaman jagung, khususnya varietas Jagung Elos yang banyak dibudidayakan di Madura. Salah satu pendekatan yang digunakan adalah memanfaatkan limbah ikan lele sebagai penyuplai unsur hara pada tanaman jagung elos . Penelitian dilakukan selama 50 hari di Desa Tobai Timur, Sampang, dengan lima variasi konsentrasi limbah lele (P1-0%, P2-25%, P3-50%, P4-75%, dan P5-100%) Dengan metode Rancangan Acak Kelompok (RAK). Hasilnya menunjukkan bahwa konsentrasi p4-75% limbah lele memberikan pengaruh paling optimal terhadap pertumbuhan tanaman baik dari segi tinggi tanaman, jumlah daun, maupun berat basah dan kering. Sebaliknya, penggunaan P5-100% limbah justru menurunkan hasil, diduga akibat kejenuhan unsur hara. Temuan ini menunjukkan bahwa limbah lele, jika digunakan dalam takaran yang tepat, dapat menjadi pupuk alternatif yang tidak hanya meningkatkan produktivitas tanaman jagung Elos, tetapi juga membantu mengurangi limbah perikanan dan mendorong pertanian yang lebih berkelanjutan.
