This study aims to evaluate the effect of nitrogen-fixing microbes and phosphate solubilizing microbes on the growth and yield of soybean. Research conducted in practicum land Faculty of Agriculture, the University of Majalengka from January to May 2019. The method used in this research was a factorial randomized block design consisting of 16 treatments repeated three times. The first factor was inoculant of nitrogen-fixing microbial (n), which consists of n0 (without inoculation), n1 (5 g inoculation MPN/kg seeds), n2 (10 g inoculation MPN/kg seeds), n3 (15 g inoculation MPN/kg seeds). The second factor was phosphate solubilize microbe (b) consists of b0 (0 kg/ha of phosphate solubilizing microbes), b1 (50 kg/ha of phosphate solubilizing microbes), b2 (100 kg/ha of phosphate solubilizing microbes), and b3 (150 kg/ha of phosphate solubilizing microbes). The differences between average were tested using Duncan's multiple range test. The analysis showed that the application of both nitrogen-fixing microbial and phosphate solubilize microbes was an effect on the growth and yield of soybean plants. N-fixing microbes and phosphate solvents effect on plant height, the number of productive branches, leaf area index, except on the number of filled pods, the number of grain per plant, weight of 100 grains, the weight of grain per plant, and weight of grain/plot, most optimal dose is 150 kg/ha MPF. The most optimal dose is 5 g for MPN inoculation and 100 kg/ha for MPF on the mean of the observed variables.

Introduction: Efforts to increase the production of breakthrough cultivation innovations that can increase the productivity of wetlands/rainy seasons that are environmentally friendly, among others, through the use of biological fertilizers. The purpose of this study was to analyze the application of adaptive cultivars and optimal biofertilizers to soybean cultivation on suboptimal land. This research will be conducted in the Experimental area of Cicurug Village from February to May 2021. Methods: research uses experimental methods in the field. The environmental design used is factorial RAK (Randomized Block Design). The first factor is cultivar and the second factor is biological fertilizer, including: K1 = Grobogan, K2 = Anjasmoro and K3 = Deja 2, the second factor is Biological Fertilizer (P) which consists of 4 levels, namely: P0 = 0 g/kg, P1 = 50 g/kg, P2 = 100 g/kg and P3 = 150 g/kg. The research variables observed were the agronomic and physiological responses of plants. Results: The results showed that the application of cultivars had an effect on the growth of soybeans grown on suboptimal land. The Anjasmoro cultivar gives better yields than other cultivars. In the application of biological fertilizers, the dose weight of 150 kg/ha was able to provide the most seeds/plot compared to other doses. Conclusion: The application of biological fertilizers and cultivars can increase soybean productivity in suboptimal land.

Introduction: Lettuce ( Lactuca sativa L.) is a popular vegetable plant in Indonesia. This is because the demand for lettuce continues to increase and lettuce plants can be planted with a hydroponic system that is currently in great demand by the community, especially generation Z (Gen Z). In meeting the demand for lettuce, lettuce is planted hydroponically. Planting in a hydroponic system often does not pay attention to the intensity of light that can be received by plants due to the shade from the GreenHouse or UV plastic used, so that plants cannot grow optimally. The purpose of this study was to find the most suitable lettuce varieties planted hydroponically at various irradiation times as well as the most appropriate long light for lettuce plant growth and to analyze the relationship between characters with the yield for indirect selection. Methods: The study was conducted at the GreenHouse Arsy Hydroponic using a Completely Randomized Design (CRD) factorial pattern. 3 lettuce varieties and 4 long light treatments were the treatments in this study. The relationship between characters was analyzed using correlation analysis. Results: The results of the study showed that the Cos and Batavia varieties can generally be used for planting with a light duration of more than 12 hours compared to the Oakleaf variety. Light duration of less than 12 hours is not recommended because it will cause the plant height to be higher, especially for the Oakleaf variety. In the indirect selection process to obtain high-yielding varieties in the hydroponic system by providing light duration and varieties can be selected from the characteristics of the number of leaves, leaf width and root length which have a significant positive correlation. Conclusion: The results of the study showed that selecting the appropriate variety can increase optimal crop yields. Information on the relationship between plant characteristics is very important to increase the effectiveness of selection.
