Response of Combined Application of Nutrient Levels with Microbial Strains on Crop Growth, Nodulation and Yield of Soybean

Abstract

The study focused to investigate the ‘Response of combined application of nutrient levels with microbial strains on crop growth, nodulation and yield 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 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 at 30 and 45 DAS compared to control. Among all the treatments, crop growth and yield (1139 kg/ha) were observed highest with 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.
