Effect of Organic Manure, Inorganic Fertilizers and Biofertilizers on Nutrient Content of Maize (Zea mays L.) and Their Residual Effect on Succeeding Wheat (Triticum aestivum L.) Crop

Abstract

An experiment was conducted at Students’ Instructional Farm, Chandra Shekhar Azad University of Agriculture & Technology, Kanpur. The aim of the study to evaluate the different sources of nutrient on nutrient content of maize (Zea mays L.) and their residual effect on succeeding wheat (Triticum aestivum L.) crop. On the basis of results emanated from present investigation it could be concluded that application of 100%RDN+25% N-VC+S+Zn+Az.+PSB significantly recorded maximum nutrient content in maize viz. N (1.58%), P (0.46%), K (0.56%) and S (0.25%) and Zn (24.20 mg kg-1) content in grain during first year and during second year nutrient content in maize grain is N (1.61%), P (0.50%), K (0.60%) and S (0.29%) and Zn (24.26 mg kg-1)similarly maximum nutrient content in maize stover viz. N (0.71%), P (0.29%), K (1.28%) and S (0.26%) and Zn (41.50 mg kg-1) during first year and during second year nutrient content in maize stover is N (0.74%), P (0.32%), K (1.31%) and S (0.30%) and Zn (41.55 mg kg-1). Similar, trend was also repeated during both of the years for succeeding wheat crop in terms of nutrient content in grain and straw of wheat. Application of 100%RDN+25% N-VC+S+Zn+Az.+PSB significantly recorded maximum nutrient content in wheat grain viz. N (1.94%), P (0.40%), K (0.64%) , S (0.30%) and Zn (42.21 mg kg-1) during first year and during second year nutrient content in wheat grain is N (1.98%), P (0.44%), K (0.68%), S (0.34%) and Zn (42.26 mg kg-1) similarly maximum nutrient content in wheat straw viz. N (0.63%), P (0.22%), K (1.38%), S (0.29%) and Zn (14.82 mg kg-1) during first year and during second year nutrient content in wheat straw is N (0.67%), P (0.25%), K (1.42%) and S (0.33%) and Zn (14.87 mg kg-1).
