Leguminous plants are plants with high protein and nutrient content, especially the protein content. Leguminous plants can grow anywhere but these plants have not been widely utilised by farmers. Some information related to leguminous plants is expected to help farmers overcome feed in the dry season. The information was obtained by reading and analysing literature and data from various research libraries that have been published in accredited journals. Tree legumes include indigofera, lamtoro, turi, gamal, and kaliandra. Indigofera plants have a crude protein content of 29.16%, while lamtoro, turi, gamal, kaliandra and Moringa are 23.8%; 31.29%; 22.6%; 25%; and 25.77% respectively. The nutrient content is supported by high productivity, where the production of indigofera, lamtoro, turi, gamal, and kaliandra can reach 4.096 tonnesBK/ha/year; 8.1 tonnes/ha/year; 2-3 tonnes/ha/harvest; 62.76 tonnes/ha/year; and 2-3 tonnes/ha/year, respectively. Despite its potential as animal feed, the plant needs further processing to reduce the anti-nutrients contained and increase its palatability so that livestock productivity increases.

Land degradation due to intensive agricultural practices is a serious issue threatening food security and ecosystem balance. Monoculture farming systems often lead to soil fertility decline, increased erosion, and reduced soil biodiversity. As an alternative, agroforestry has been developed to enhance agricultural productivity without compromising soil health. Agroforestry integrates agricultural crops with trees or other woody plants in a mutually beneficial system. Several studies have shown that agroforestry improves soil organic matter content, retains soil moisture, and reduces erosion and nutrient loss. This study employs a literature review method to analyze the effectiveness of agroforestry in improving soil health and agricultural productivity. Agroforestry has been found to enhance agricultural productivity through crop diversification, efficient land use, and climate change mitigation. Diversification not only strengthens food security but also increases farmers’ income by minimizing crop failure risks and enhancing nutritional value. Additionally, agroforestry optimizes land use by improving yield per unit area and reducing environmental degradation through natural resource conservation. Agroforestry also plays a crucial role in mitigating climate change by increasing ecosystem resilience, sequestering carbon, and reducing extreme weather impacts. However, the adoption of agroforestry faces challenges, including a lack of farmers’ knowledge, limited policy support, and varying environmental conditions. Addressing these barriers through improved education, supportive policies, and sustainable resource management can accelerate agroforestry adoption. With broader implementation and strong policy support, agroforestry can drive agricultural sustainability and enhance community well-being.

One of the practical foods that can fulfill nutritional needs is flakes. Flakes that available on the market are generally made from wheat and corn. The nutritional value of corn flour-based flakes can be enhanced by combining them with other ingredients that have a relatively high protein content. One such food ingredient with a high protein content is mung beans. The development of flakes products using mung bean flour is expected to be one of the way to optimize the use of local legumes in Indonesia. The aim of this study is to obtain the best formulation of corn flour and mung bean flour in terms of the physicochemical and organoleptic characteristics of the flakes. This study uses a randomized block design with 4 treatment levels, which are the formulation ratios of corn flour to mung bean flour (60:40, 65:35, 70:30, 75:25), with each treatment repeated 6 times. The observation parameters include physicochemical characteristics such as protein, water and ash content, while sensory characteristics include aroma, taste, crispiness, color, and overall preference. The best treatment is determined by the de Garmo effectiveness index. The results of the study show that the 65% corn flour and 35% mung bean flour formulation is the best treatment based on the effectiveness index test with a score of 0.77, with physicochemical characteristics of 2.717% moisture content, 3.026% ash content, and 6.891% protein content, as well as sensory characteristics of color 4.2 (more liked), aroma 3.93 (liked), crispiness 4.26 (more liked), taste 4.23 (more liked), and overall preference 4.2 (more liked).

Fertilizer is an important factor in increasing the growth and yield of chili plants (Capsicum annuum L.). The selection of the right type of fertilizer greatly determines productivity and environmental sustainability in the long term. This study aims to analyze the differences between chemical fertilizers and organic fertilizers in chili plant cultivation, including plant growth, yields, and their impact on soil fertility. The method used is a literature review by examining various previous studies that discuss the effectiveness of both types of fertilizers. The results of the analysis show that chemical fertilizers provide faster growth and higher yields in the short term because their nutrients are more easily absorbed by plants. However, excessive use can cause soil degradation, decreased organic matter content, and environmental pollution. In contrast, organic fertilizers work more slowly, but are able to increase soil fertility, improve soil structure, and support the balance of agricultural ecosystems in the long term. The combination of chemical and organic fertilizers has proven to be the best strategy in increasing chili productivity while maintaining soil health. Therefore, balanced fertilization with the right dose is highly recommended to ensure optimal harvest results without damaging the environment.

This research aims to determine the effect of using biochar and guano fertilizer on the growth and resistance of pakcoy to drought stress and it is hoped that this research will add information for the development of pakcoy plant cultivation techniques that are more adaptive to dry land.

This study employs a meta-analysis or literature review method to examine previous research on the role of microorganisms in agriculture, specifically on how microorganisms play a critical role in sustainable farming. Most available studies rely on qualitative data or case studies, limiting the ability to conduct more in-depth quantitative analysis. The results indicate that waste processing into organic compost fertilizer is crucial. Applying organic farming methods improves crop quality while maintaining ecosystem balance.

The use of fertilizer in plant cultivation is basically carried out to meet the availability of nutrients for plants in order to obtain optimal results. However, excessive use of fertilizer can actually have a negative impact on the ecosystem, such as environmental pollution and decreasing soil quality. The use of biofertilizer as a substitute for biological fertilizer is an alternative that can be used to reduce dependence on chemical fertilizers. Biofertilizer is a biological fertilizer containing various live microorganisms which is used to increase plant productivity by improving the quality of soil fertility. One of the microbes that acts as a biofertilizer is the Bacillus sp. The purpose of this article is to find out how Bacillus sp. functions as a biological fertilizer that can increase soil fertility and increase crop productivity. Bacillus is a genus of bacteria that can be used as a biofertilizer because of its more varied antagonistic mechanisms and ability to produce endospores. The method used in this article is a meta-analysis or literature review method in several journals published online which are integrated with Google Scholar.

Organic farming has increasingly become a preferred choice in sustainable agricultural systems due to its significant benefits for environmental balance and quality. One of the key elements in organic farming is soil microorganisms, which play a crucial role in enhancing soil fertility and supporting plant health. Soil microorganisms, such as nitrogen-fixing bacteria, phosphate-solubilizing microbes, mycorrhiza, and organic matter decomposers, contribute significantly to fertilization efficiency and nutrient availability, as well as improving plant resistance to pathogens. The utilization of soil microorganisms as biofertilizers can reduce dependency on chemical fertilizers, mitigate environmental pollution, and increase agricultural productivity sustainably. Furthermore, soil microorganisms can improve soil structure, extend root longevity, and stimulate plant growth. The selection of appropriate microorganisms according to soil conditions and intended use is essential to maximize their benefits. Therefore, the application of soil fertility-promoting microorganisms as part of sustainable agricultural technology holds great potential to enhance environmentally friendly and efficient agricultural outcomes.
