Integrated Nutrient Management Practice for Maize-Wheat Cropping System in Chhotanagpur Plateau Region

The experiment was carried out during two consecutive years of 2020-22 under the ongoing permanent manurial trial with different nutrient management practices under maize-wheat system since 1983-84 at Birsa Agricultural University, Kanke, Ranchi to study the productivity and profitability under maize-wheat cropping system. The application of 50%N through FYM along with 50% RDF through chemical fertilizer to maize fb 100% RDF through chemical fertilizer to wheat produced maximum and significantly higher grain yield (46.92 and 47.96 q/ha of maize and wheat, respectively) than other nutrient management practices and statistically at par with application of 25%N through FYM along with 75% RDF through chemical fertilizer to maize fb 75% RDF through chemical fertilizer to wheat (45.04 and 45.53 q/ha of maize and wheat, respectively). Highest net return (₹. 50583.00 in maize and ₹.79643.00 in wheat) and B:C ratio (1.32 in maize and 1.87 in wheat) was with the application of 50%N through FYM along with 50% RDF in kharif and 100% RDF in rabi which was statistically at par with the application of 25%N through FYM along with 75% RDF in kharif and 75% RDF in rabi (₹.47900.00 and ₹.75237.00) & B:C ratio (1.28 and 1.83) in maize and wheat respectively.
