The effect of silica liquid fertilizer from straw and formulation of bacillus sp for rice growth (Oryza sativa L.) and tolerance to fungi Pyricularia oryzae Cav

Abstract

Blast disease caused by Pyricularia oryzae.This disease which generally was caused by environmental conditions, plant age, and the level of plant resistance. One of effort to control it was used insecticides, where more used could adversely affect the environment due to toxic chemical residues. The purpose of this study was to determine the effect of the used of silica liquid fertilizer from straw and the formulation of Bacillus sp for the growth of rice and tolerance to diseases of blast or Pyricularia oryzae. The method was the factorial RAKL pattern with 2 treatment factors that were dosage formulation of Bacillus sp and the composition of liquid silica fertilizer with 6 repications for each treatment. Data analysis was used ANOVA with significant level of 5% and continued with the Smallest Significant Difference Test (DMRT). The results of the study showed that the added of liquid silica with a concentration of 12 ml and the formulation of Bacillus sp 6 grm / pot gave a significant effect on plant height, number of leaf tillers, and mean percentage of damage to rice.
