Abstract:

A field experiment was conducted during kharif 2012 in Inceptisols of Northern hills zone of Chhattisgarh to estimate the nutritional requirement, efficiencies of fertilizer, soil test and organic source (FYM) to estimate the fertilizer requirement for varying yield goals of maize crop based on soil test levels using INM approach. Maize crop required 1.59 kg N, 0.32 kg P and 1.84 kg K for one quintal grain production. Fertilizer and soil test efficiencies estimated were 41.84 and 22.53 percent, respectively for N, 28.28 and 52.67 percent, respectively for P and 140.33 and 26.40 percent, respectively for K. The FYM contribution in terms of N, P and K were estimated 21.76, 4.70 and 12.81 per cent, respectively. Based on these basic parameters, fertilizer adjustment equation for N, P and K were evolved for different yield targets of maize based on soil nutrients level using FYM as organic component in INM.
