| dc.description.abstract | In-vitro studies were conducted to isolate protease producing bacteria at the Department of Agricultural Microbiology, University of Agricultural Sciences, Dharawad during 2017-18. As many as 68 proteolytic bacterial isolates were isolated from different sources viz., soybean rhizospshere, rotten green peas and soil enriched with glyricidia and subabul using soy meal agar medium. Ten promising isolates were selected based on enzyme potency and PPB-3 was the most efficient isolate in terms of enzyme activity. Soy meal was fermented with PPB-3 under optimized conditions and found to posses higher nutritional, phytochemical and microbiological composition when compared with other treatments. Cowpea germination percentage and seedling vigour index were significantly increased due to priming of seeds with soy meal protein hydrolysate @ 10 per cent (108 and 141.86 % respectively) compared to control. Effect of spraying soy meal protein hydrolysate at different concentrations on cowpea was carried. Out of four concentrations, spraying twice @ 10 ml L-1 resulted in increased growth of plant and higher relative chlorophyll content. The treatment also significantly increased microbial population both in the rhizosphere and phyllosphere with a concomitant increase in the soil enzyme activities such as dehydrogenase, urease and phosphatase. Spraying cowpea seedling with soy meal protein hydrolysate significantly increased pod and grain yield. The highest pod yield (8.44 g plant-1) and grain yield (12.23 g plant-1) were obtained by spraying soy meal protein hydrolysate twice @ 10 ml L-1. The present investigation clearly brought out the potential of soy meal protein hydrolysate in stimulating rhizosphere and phyllosphere microbiological population and their activities in terms of soil enzymes eventually improving growth and yield of cowpea. | |
