Abstract:
The experiment was conducted in <em>kharif</em> 2016 on hybrid maize comprising five treatments with and without incorporation of crop residues along with chemical fertilizers, viz. NPK (250:120:120 kg/ha), N<sub>0</sub>PK (0:120:120 kg/ha), NP<sub>0</sub>K (250:0:120 kg/ha), NPK<sub>0</sub> (250:120:0 kg/ha) and SSNM (200 kg N: 90 kg P<sub>2</sub>O<sub>5</sub>: 100 kg K<sub>2</sub>O /ha) to study the effect of crop residue incorporation in hybrid maize on nutrient status. Results showed among the different treatments ample dose of fertilizers application gave highest yield 87.69 and 83.63 q/ha in with and without crop residues incorporated plots. Minimum yield obtained in the N omitted plots (16.98 and 16.00 q/ha with and without incorporation of crop residues). The highest available nitrogen, phosphorus, potassium and sulphur status was found 224.40, 117.81, 236.36 and 117.69 kg/ha and the lowest 219.81, 110.34, 208.73 and 112.70 kg/ha when crop residue was incorporated and without incorporation of crop residue respectively. The significantly (P&lt;0.05) higher levels of available phosphorus of residue treated plots was found due to phosphorus - released from the decomposition of crop residues.Maximum nutrient uptake (N – 278.74 &amp; 265.89, P – 45.77 &amp; 43.69, K – 112.8 &amp; 109.15 kg/ha) was obtained when ample dose of nutrients were applied and minimum (N – 48.34 &amp; 45.39, P – 7.29 &amp; 6.82, K – 27.35 &amp; 26.07 kg/ha) uptake was observed in the treatments where N was omitted. Whenever uptake was compared with incorporation of crop residues and without incorporation of crop residues, total uptake of nutrients were more in crop residues incorporated plots than without incorporation of crop residues. Total nutrients uptake (N, P, K) of all treatments were higher with incorporation of crop residue. However maximum response of crop residue (N 10.52%, P 11.25% &amp; K 8.37%) were found in the K omitted plots
