Abstract

At present due to continuous use of phosphatic and potassic fertilizers, a deposits of these nutrients have increased in the soil of studied area, and Bacillus megaterium and Bacillus mucilaginosus solubilize/mobilize P and K in the soil, thus, for increasing yield and quality of soybean, an experiment was planned with the aim to investigate the response of Bacillus megaterium and Bacillus mucilaginosus strains on yield and quality of soybean [Glycine max (L.) Merrill.] at All India Coordinated Research Project (AICRP) on Integrated Farming System Research at College of Agriculture, Indore, Madhya Pradesh, India during kharif, 2019 & 20. The research was conducted in randomized block design (RBD) with 8 treatments, viz. Control with 75% RDF (T1), Control with 100% RDF (T2), 75% RDF with Bacillus megaterium and Bacillus mucilaginosus strains as seed treatment (T3), 100% RDF with Bacillus megaterium and Bacillus mucilaginosus strains as seed treatment (T4), 75% RDF with Bacillus megaterium and Bacillus mucilaginosus strains as foliar application at 30 and 45 DAS (T5), 100% RDF with Bacillus megaterium and Bacillus mucilaginosus strains as foliar application at 30 and 45 DAS (T6), 75% RDF with Bacillus megaterium and Bacillus mucilaginosus strains as seed treatment + foliar application of Bacillus megaterium and Bacillus mucilaginosus strains at 30 and 45 DAS (T7) and 100% RDF with Bacillus megaterium and Bacillus mucilaginosus strains as seed treatment + foliar application of Bacillus megaterium and Bacillus mucilaginosus strains at 30 and 45 DAS (T8). The seed yield (1139 kg ha-1) of soybean increased to the tune of 14.26 and 19.72 per cent with application of 100% RDF with Bacillus megaterium and Bacillus mucilaginosus strains as seed treatment + foliar application of Bacillus megaterium and Bacillus mucilaginosus strains (T8) at 30 and 45 DAS compared to control (786 kg ha-1). Among all the treatments, yield attributes such as pods count plant-1 (29.66), seeds count pod-1 (3.36) and seed yield plant-1 (13.17) were observed highest with T8 at 30 and 45 DAS.
