Organic fertilizer application to improve bacterial quality and rice production

Abstract

Organic fertilizers are very useful for increasing the nutrient content needed by plants, increasing plant productivity, stimulating the growth of plant organs and fertilizing the soil. This study aims to determine the increase in the quality of bacteria and production of rice plants (Oryza sativa). The research was carried out in paddy fields belonging to the Agriculture Service of Bone Bolango Regency, Gorontalo Province, Indonesia, from September to December 2022. The researchusing Completely Randomized Block Design with 6 treatments 3 replications. The plant used is rice Cakrabuana variety.Plant spacing using the Jajar Legowo system 4: 1 with a spacing of 15 cm x 22 cm and a row width of 40 cm Legowo.The plot size used is (10 x 5) m. The bacterial population was calculated using the SANICHECK kid bacterial test. The dose of Granul organic fertilizer that uses 10 tons and 20 tons/hectare. The research results show thatGranule organic fertilizer 20 tons/hectare can improve the quality of bacteria from 10.13 to 10.17 cfu/ml compared to other treatments. Granular organic fertilizer 20 tons/hectareand recommended NPK is the best treatment that can increase the production of harvested dry grain by 7.4 tons/hectare and dry milled grain by 4.24 tons/hectare.
