The effectiveness of beyonic startmix organic biological fertilizer on growth and yield of Inpari rice 30

Abstract

Increasing agricultural production, especially rice, uses a lot of chemical fertilizers, which can have a negative effect on the environment. The solution sought to overcome the impact of using chemical fertilizers is using biological organic fertilizer (POH) beyonic startmix, which contains microorganisms that provide plant nutrients, produce growth hormones, and protect plants from pests and diseases. The study aimed to determine the effect of startmix beyonic organic fertilizer on the growth and yield of inpari 30 rice. The study was carried out in the Motekar farmer group’s paddy fields in Jabong Village, Pagaden District, Subang Regency. The study lasted four months, starting from January to April 2018. The study used a field experiment method using a Randomized Block Design (RBD) pattern, which consisted of 2 treatments, namely with fertilization and without fertilization with startmix beyonic biological organic fertilizer, each carried out on three plots with five replicates. Parameters observed included plant height, number of tillers, number of panicles, number of grains per panicle, the weight of 1000 dry grain seeds, and grain yield. The results showed that applying POH significantly affected the number of tillers, panicles, and paddy yields. The yield of dry milled grain with POH was, on average, 7.463 tons/ha, 16.91% higher than without POH fertilization at 6.201 tons/ha on average.
