چکیده
A long-term field experiment was conducted to study the effects of different combinations integrated nutrient management (INM) on carbon sequestration and wheat yield in a rice-wheat cropping system. The consisted 11 treatments that were replicated three times. organic manures used included farmyard manure (FYM), straw (WS), green (GM) with Sesbania aculeata . results revealed application 50% recommended dose fertilizers (RDF) along nitrogen (N) through FYM during rice cultivation, RDF led significant increase soil (SOC). Specifically, SOC content enhanced by 46.4% (18.29 Mg ha -1 ) compared wheat, resulting C rate 0.22 year These increases higher combined inorganic inputs. Additionally, substituting cultivation resulted 24.7% grain wheat. INM treatments, showed significantly ( p ≤ 0.05) agronomic efficiency (AE) (N), phosphorus (P) potassium (K), partial factor productivity (PFP) N, P K, pool index (CPI) at dose. Moreover, also exhibited lower greenhouse gas (GHG) emission intensity. Application neither chemical nor (T 1 maximum GHG intensity (328.1 kg CO 2 eq −1 yield). Based these findings, it can be concluded use increased crop while reducing emissions system eastern Indo-Gangetic Plains (EIGP) India.

Residual phosphorus and zinc influence wheat productivity under rice-wheat cropping system.
Continuous cropping of rice (Oryza sativa L.) and wheat (Triticum aestivum L.) deplete soil fertility and crop productivity. One strategy to increase crop productivity under rice-wheat system is balanced application of crop nutrients. Field experiment was conducted to assess the impact of phosphorus (0, 40, 80, 120 kg P ha(-1)) and zinc (0, 5, 10, 15 kg Zn ha(-1)) on the productivity of rice ge...

Integrated Nutrient Management for Wheat by Municipal Solid Waste Manure in Rice-Wheat and Cotton-Wheat Cropping Systems
The effects of integrated nutrient management (INM) by municipal solid waste manure (MSWM) on wheat yield were studied in rice-wheat and cotton-wheat systems. each site was used as an independent experimental unit. Two fertilizer doses (conventional and site-specific) were applied in each of three improved techniques: chemical fertilizers, and MSWM plus chemical fertilizers with and without pes...
