Abstract

Introduction: Soybean is one of the main sources of vegetable protein. Seventy percent of the soybean needs in Indonesia is still imported, due to the low crop productivity and the declining area of soybean planting. Sonic bloom technology is an alternative to increase soybean productivity. This study aims to determine the pattern of the relationship between foliar fertilization intervals in the use of sonic bloom technology with soybean varieties. Method: The research used a factorial experiment using a randomized block design (RBD). The first factor is the interval of using sonic bloom, I5: 5-day interval, I10: 10-day interval, and I15: once every 15 days. The second factor was soybean varieties, VA: Anjasmoro, VD: Dega-1, and VM: Mallika (black soybean). The data obtained were analyzed for Analysis of Variance with the Fα = 0.05 test followed by the 5% Honest Significant Difference (HSD) test and correlation regression analysis.The results showed that different soybean varieties have different responses to plant length, number of leaves and leaf area at different intervals of sonic bloom exposure. Result: Soybean plants with thicker hairs (trichomes) such as the Dega-1 variety require the use of sonic bloom technology with shorter intervals compared to varieties with sparse hairs such as Anjasmoro and Mallika black soybeans. Conclusion: The use of sonic bloom technology was able to increase the productivity of soybean varieties Anjasmoro, Mallika and Dega-1 each by 68.3%; 48.3% and 10.5%.

Abstract

This study provides an innovation in making compost from rice straw (low quality) mixed with peanut residue (high quality) to improve the quality of rice straw compost. The purpose of this research was to discover the optimum composition of a mixture of peanut residue and straw for mineralization, absorption, and Nitrogen Use Efficiency (NUE) and its effect on upland rice plants. The study was conducted in three stages. The first stage determined the quality of five compost mixtures: C1, C2, C3, C4, and C5. The second phase of testing for cumulative N minerals was performed after 1, 2, 4, and 8 weeks of incubation. The third stage examined the impact of the compost mixture on the growth and yield of upland rice in comparison with two treatments, namely the control and NPK fertilizer. The results showed a similarity in the forms of mineralization, where the cumulative N mineral increased with the addition of peanut residue to the compost mixture. The use of a mixture of peanut residue and rice straw compost increased net mineralization by 37.27% (C5) to 59.48% (C1), N uptake by 49.19% (C5) to 62.95% (C3), and NUE by 15.04% (C4) to 51.48% (C3). A strong relationship was detected between the quality of the compost and the forms of N in the soil, particularly the nitrate content, total N minerals, and N microbial biomass, with correlation coefficients of 0.92, 0.88, and 0.94, respectively. A strong to very strong relationship was detected between N form and N uptake (r = 0.84), plant height (r = 0.79), number of tillers (r = 0.78), yield of rice plants (r = 0.93 (plant total dry weight), and r = 0.76 (grain weight). The optimum N uptake, NUE, and yield of upland rice were shown by C3 treatment of 405.28 mg pot-1, 42.21%, and 6.19 tons ha-1, respectively.
