tailieunhanh - Post-harvest soil available nutrient status and microbial load as influenced by graded levels of nitrogen and biofertilizers

A field experiment was conducted in sandy clay loam soil of . Agricultural College Farm, Tirupati with three levels of nitrogen viz., 75, 100, 125 % RDN and five biofertilizers viz., Azospirillum, phosphorus solubilizing bacteria (PSB), potassium solubilizing bacteria (KSB), zinc solubilizing bacteria (ZnS) and combined application of Azospirillum + PSB + KSB + ZnS each applied @ 5 kg ha-1 in randomized block design with factorial conceptin kharif maize. The experimental results revealed that significantly higher grain yield of maize and post-harvest nutrient status of soil as well as soil microbial load of bacteria, fungi and actinomycetes were recorded with 125 % RDN followed by 100 % RDN. |
