Abstract

The organic nitrogen (N) nutrition of organic manuring with biofertilizers had the high‐ est rice equivalent grain yield, production efficiency, net energy return, as well as net monetary return and profitability in rice-based cropping sequence. The different ricebased cropping sequences did not differ with respect to yield and quality parameters. However, the organic N nutrition with organic manures along with biofertilizers proved significantly superior with respect to yield and quality parameters of rice, potato, and on‐ ion, respectively. The different rice-based cropping sequences differ with respect to nu‐ trient uptake, e.g., rice-maize-onion had the highest removal of major (N, P, K), secondary (S), and micronutrients (Zn, Fe, Mn, Cu) than the rest of cropping sequence, which was significantly superior to the rest of the sequences. The organic N nutrition with organic manures along with biofertilizers proved superior due to its visible favora‐ ble effect on soil health with respect to nutrient status and microbial count and this indi‐ cates the utilization of this low-cost but long-term beneficial practice under high-intensity cropping for sustainable crop production.
