COMBINATION OF BIOLOGICAL AND ANORGANIC FERTILIZER ON GROWTH AND PRODUCTION OF RICE (Oryza sativa)

Abstract

Rice is the major commodity most consumed by people in Indonesia. Rice production fluctuates every year, one of which is because the carrying capacity of nutrients obtained by plants is less than optimal. Nutrients can come from a combination of biological and anorganic fertilizers. This study aimed to determine the combination of biological and anorganic fertilizer application on the growth of rice. The experimental design used was a randomized block design with 4 replications. The treatments were arranged in 5 levels of fertilization, namely: without application of fertilizer (P0), 1.00 dose of NPK (P1), 1.00 dose of NPK + 1.00 dose of biological fertilizer (P2), 0.75 dose of NPK + 1.00 dose of biological fertilizer (P3) and 0.50 dose of NPK + 1.00 dose of biofertilizer (P4). The test results showed that the treatment of P3 produced taller plants, more tillers, and darker green leaves than the control treatment (P0) and was the same as treatment with P1. The treatment of P3 also resulted in a higher number of productive tillers, increased tile, and the estimated productivity of GKP (harvested dry grain) and GKG (dry milled grain) was higher than the control treatment (P0) and equal to Jurnal Bioindustri Vol. 5.
