Integrated management of nitrogen and phosphorus in maize (Zea mays) and their residual effect on cowpea (Vigna unguiculata)



Integrated management of nitrogen and phosphorus in maize (Zea mays) and their residual effect on cowpea (Vigna unguiculata)



Indian Journal of Agricultural Sciences 70(2): 119-121



In field trials at Bangalore, Karnataka, India in the summer and in the rainy seasons of 1996 on sandy loam soil of pH 6.6, application of single superphosphate and rock phosphate, Azotobacter chroococcum and Aspergillus awamorii, 3 rates of farmyard manure and N fertilizers to maize to be followed by Vigna unguiculata was investigated. Single superphosphate was the preferred P source, both bioinoculants improved plant growth, and up to 25% farmyard manure did not reduce maize yields.
