Abstract Widespread yield stagnation and productivity declines in the rice–rice cropping system have been reported many of associated issues are related to soil quality. A long‐term experimental study was initiated 1969 assess impact continuous cultivation rice as a single crop grown wet well dry seasons using varying levels chemical fertilizer manure applications on quality indicators (physical, biological), sustainable index ( SYI ) SQI ). The treatments comprised fertilizers farmyard FYM...
Soil phosphorus (P) fractionation, adsorption, and desorption isotherm, rice yield P uptake were investigated in flooded tropical (Oryza sativa L.) following 42-year fertilizer manure application. The treatments included low-input [unfertilized control without N, P, or K (C0N0)], farmyard (FYM) (C1N0), NP (C0NP), NPK (C0NPK), FYM + (C1NP), high-input treatment, (C1NPK). Grain was increased significantly by 74% over the under combined application of NPK. However, low- treatments, as well...
Rice-rice system and rice fallows are no longer productive in Southeast Asia. Crop varietal diversification of the based cropping systems may improve productivity profitability systems. Diversification is also a viable option to mitigate risk climate change. In Eastern India, farmers cultivate during rainy season (June-September) land leftovers fallow after harvest post-rainy (November-May) due lack sufficient rainfall or irrigation amenities. However, lowland areas, residual soil moistures...
Rice is a major cereal crop and staple food of eastern India, most farmers depend solely on rice for their livelihood. farming provides both tangible non-tangible benefits to ecosystems which need be maintained enhanced. These are provided through ecosystem services (ES) that include marketable non-marketable. In this study, the farms in India were valued by quantifying economic value under conventional method cultivation gap farm income per unit area assessed. A stratified random sampling...
