Corn seeds have high nutritive values and used as food while its stover is used as fodder, feed and fuel therefore, Its demand is increasing day by day. Thus, for higher soil productivity and vigorous fertility for longer run, the importance of integrated plant nutrient management system (IPNS) has increased. Inspite of higher and sustaining crop yield, fertilizer and manure management in corn crop production is also desirable for environmental reasons. The aim of present investigation was to study the â€œInfluence of IPNS on Crop Growth Rate, N2
O contents and their intake by seed and stover in corn.â€ Results showed that the crop growth rate (CGR) of corn was more at knee high to tasseling stage, which gradually declined towards the maturity during both the years of experimentation. Significant increase in CGR was recorded in treatments receiving organic, inorganic and bio-fertilizer sources of nutrients in combination. N2
O content and their intake in
corn seed and stover obtained highest under treatment T3
(FYM + Chem.) followed by T8
(Azotobactor + Rhizobium
+ PSB + Chem.) and T7
(Azotobacter + Rhizobium
+ PSB + Chem.) which were significantly superior to other treatments during both the years of investigation. The substitution of a part of inorganic fertilizer by organic sources and bio-fertilizers is the best approach to improve soil health for sustainable crop production. By adopting integrated plant nutrient supply we can get maximum yield with higher economic returns without causing soil pollution and spoiling soil health on long term basis.
