Abstract

This study was aimed to know the yield of edamame soybean by applyingshoot pruning treatment and determining the ratio of NPK fertilization. Thisresearch was carried out in Sempolan Village, Silo Sub-district, Jember Regencyfrom October 2019 to January 2020. This research employed a factorialrandomized block design (RBD) consisting of 2 factors, 3 replications, and 9treatments. Factor W was shoot pruning which consisted of 3 time levels, namely0 DAS (control), 15 DAS, and 25 DAS. P factor was the ratio of NPK fertilizationwhich consisted of 3 levels, namely 250 kg / ha, 500 kg / ha, and 750 kg / ha witha combination of W1P1, W1P2, W1P3, W2P1, W2P2, W2P3, W3P1, W3P2, andW3P3 treatments. Data were analyzed by using ANOVA variance and furthertested by using DMRT test at the 5% level. The research results indicated that thetreatment of shoot pruning had a very significant effect on the plant heightparameter and the number of branches. The treatment of NPK fertilization did nothave a significant effect on all parameters. The interaction of shoot pruning andNPK fertilization also did not have a significant effect on all parameters.
