Abstract
A field experiment is carried out during June to November, 2014 to study the impact of chemical fertilizers with biofertilizer (EM1) on the yield of rice and its components (Oryza sativa L.), cv.Yasamin. The experiment is done using Completely Randomized Block Design with three replicates. There are four treatments of mixed fertilizers, urea and biofertilizer (EM1) that is used in this study, T1 (recommended dose of chemical fertilizer for rice), T2 (biofertilizer + 1/4 recommended dose of chemical fertilizer for rice), T3 (1/2 recommended dose of chemical fertilizer for rice) and T4 (biofertilizer + whole recommended dose of chemical fertilizer for rice). Significantly, increases are observed in seeds per panicle, 150.9, number of tillers.m-2 462 and grain yield, 5.31 Mg. ha-1 in T4 treatment). Using biofertilizer (EM1) reduces spikelet sterility to 4%.
