Abstract

This study examines how the use of biofertilizer and intercropping methods impacts the growth and pod yield of different soybean cultivars. The research involved six high-quality soybean cultivars, which were treated with Fermented Liquid Organic Fertilizer (LOF) Azolla at various doses. The researchers also considered environmental factors and soil fertility conditions during the evaluation. The findings revealed that environmental factors play a crucial role in influencing the growth of soybean plants. Additionally, suboptimal soil fertility, as well as pest, disease, and weed infestations, presented challenges to soybean productivity. Through careful analysis, the researchers identified that cultivar K2 (Anjasmoro) treated with a dose of 250 ml/L LOF displayed the best performance. Notably, positive correlations were observed between plant height, number of filled pods, and seed weight per plot. The use of biofertilizer and intercropping systems demonstrated significant potential in promoting sustainable soybean productivity. Consequently, this study contributes to the development of sustainable farming practices and offers insights to enhance soybean production in an eco-friendly manner.

Abstract

This research explores the impact of intercropping corn and soybean, along with the combined effects of Azolla pinnata dose, the best soybean variety, and cytokinin concentration, on enhancing the physiology and agronomy of the plants. The study was conducted using 36 experimental units in a plot between soybean and corn. Various parameters were observed, including seed viability and vigor, soil analysis, nutrient content analysis of POC Azolla pinnata, temperature, air humidity, sunlight radiation, rainfall, pest infestation, diseases, and weeds. Additionally, plant height, leaf count, secondary branch count, total plant dry weight, leaf chlorophyll, leaf area ratio, leaf chlorophyll index, and stomatal conductance were measured. The data were analyzed using Djajasukanta and Sitompul-Guritno calculations, focusing on the average relative growth rate (RGR), average net assimilation rate (NAR), and root-shoot ratio (RSR). The results demonstrated that intercropping corn and soybean with the combination of Azolla pinnata dose, the best soybean variety, and cytokinin concentration had a positive impact on soybean production and quality. The Anjasmoro variety showed favorable outcomes in various parameters, such as plant height, leaf count, and branch count. Physiological leaf analysis revealed that the treatment combination with the Anjasmoro variety exhibited optimal photosynthetic rates and chlorophyll content, indicating higher photosynthesis efficiency. Moreover, the treatment with the Dega 1 variety displayed faster growth and efficient resource allocation, as evident from the high RSR value. The selection of the best soybean variety, Azolla pinnata dose, and cytokinin concentration can lead to sustainable improvements in soybean crop yield. These findings hold significant implications for agricultural management and enhancing food security.

Abstract

Soybean is lots of plants contain beneficial nutrition for Indonesian society. The need for soybeans continues to increase every year while national soybean production is still low. One of the efforts to increase soybean production is by intercropping with corn. Competition in obtaining growth factors, one of which is nutrients, is a major problem in intercropping, therefore it is necessary to add environmentally friendly nutrients such as Azolla pinnata. This study aims to analyze the performance of soybean cultivars planted by intercropping with corn by administering LOF Azolla pinnata. The research method used a randomized block design (RBD) which consisted of 24 treatment combinations and was repeated twice to see the effectiveness of the treatment, analyzed with response surface regression. The results of the research show Cultivars Anjasmoro, Dega 1 and Gepak Kuning show most agronomic appearance good with administration of LOF Azolla dose 400 ml.L -1. results study this show giving LOF to cultivation plant in a manner intercropping could conducted for minimize impact negative competition between plant on system intercropping. Selection could conducted with see correlation between character which have correlation most tightly with character result.

Abstract

Soybean productivity in Indonesia remains fluctuative and has not yet met national demand, partly due to limited land availability and competition with other crops. Intercropping systems combined with the application of Azolla-based liquid organic fertilizer (LOF) are considered a potential strategy to improve land use efficiency and crop yield. This study aimed to analyze the productivity and Land Equivalent Ratio (LER) of soybean–maize intercropping as affected by Azolla liquid organic fertilizer application on different soybean cultivars. The experiment was conducted in Sanca Village, Gantar District, Indramayu Regency, from July to October 2022 using a non-factorial Randomized Block Design with 30 treatment combinations consisting of six soybean cultivars (Anjasmoro, Dega 1, Deja 2, Dering 1, Gepak Kuning, and Grobogan) and five concentrations of Azolla liquid organic fertilizer (0, 100, 200, 300, and 400 mL L⁻¹), with two replications. Data were analyzed using analysis of variance followed by the Scott–Knott grouping test at the 5% significance level. The results showed that the combination of soybean cultivars and Azolla liquid organic fertilizer significantly affected soybean growth and yield, maize yield, and LER values in the intercropping system. The highest soybean productivity in intercropping was obtained from the Anjasmoro cultivar combined with 400 mL L⁻¹ of Azolla liquid organic fertilizer, while the highest LER value was recorded in the intercropping of maize with the Dering 1 cultivar. All intercropping treatments resulted in LER values greater than 1, indicating that soybean–maize intercropping was more efficient than monoculture systems. Therefore, appropriate selection of soybean cultivars combined with Azolla liquid organic fertilizer application can enhance productivity and land use efficiency in soybean–maize intercropping systems.

Abstract

Weed infestation in maize fields can reduce crop growth and yield due to competition for light, water, and nutrients. The use of herbicide mixtures is considered an effective strategy to improve weed control efficacy while minimizing the risk of weed resistance. This study aimed to evaluate the efficacy and crop safety of a herbicide mixture containing atrazine 200 g/l, topramezone 10 g/l, and nicosulfuron 15 g/l on weed control, growth, and yield of maize (Zea mays L.). The research was conducted in Majalengka Kulon Village, Majalengka Regency, West Java, using a non-factorial randomized block design with six treatments and four replications. Treatments consisted of herbicide doses of 1.50, 2.00, 2.50, and 3.00 l/ha, manual weeding, and an untreated control. Observed variables included weed composition and dry weight, phytotoxicity levels, growth parameters, and yield components of maize. The results indicated that the herbicide mixture effectively suppressed dominant weed populations without causing phytotoxic effects on maize plants. The application rate of 2.50 l/ha resulted in the most favorable balance between weed control efficacy and crop safety, suggesting its potential to optimize maize productivity.
