Effect of Arbuscular Mycorrhizal Fungi (AMF) and PGPR Application on Paddy Yield Components

Pengaruh Aplikasi Fungi Mikoriza Arbuskular (FMA) dan PGPR Terhadap Komponen Produksi Tanaman Padi

Abstract

o increase the productivity of rice plants, the use of biological fertilizers based on Fungi or beneficial bacteria is very necessary to be carried out through experiments so as to obtain maximum benefits by finding or obtaining the right dose and concentration in spurring the growth and production of rice plants Where in the future the environmental effects of the use of non-organic fertilizers must be really considered and eliminated in order to prevent more severe environmental damage, besides that the use of biological fertilizers and other organics is very urgent. For this reason, the research aims to study the effect of the application of Arbuscular Mycorrhizal Fungi (AMF) and PGPR, especially on plant Yield components. The research was designed with a 2-factor Split Plot design, pattern consisting of the main plot is PGPR application consisting of concentrations of 10, 20 and 30 ml/L plus control treatment and the subplots are AMF doses of 10, 20, and 30 grams per plant respectively. The experiment was conducted on 50 cm x 50 cm plots. The application of AMF was carried out on rice seedlings during transplanting while PGPR application began 7 days after transplanting. Observations were made on generative or production parameters including the number of panicles per plant, grain weight per plant and grain weight per plant. The results showed that the application of mycorrhiza dose as much as 30 g per plant gave the best effect on the number of production components of the number of panicles, the number of grains, the grain
contained with a better average compared to plants that were not treated with mycorrhiza (AMF), as well as the
application of PGPR as much as 30 ml / L had a real effect and gave the best results on the number of panicles,
the average grain weight, and the average grain weight contained and all better than plants that were not treated
with PGPR.
