Crop and varietal diversification of rainfed rice based cropping systems for higher productivity and profitability in Eastern India
Rice-rice system and rice fallows are no longer productive in Southeast Asia. Crop and varietal diversification of the rice based cropping systems may improve the productivity and profitability of the systems. Diversification is also a viable option to mitigate the risk of climate change. In Eastern India, farmers cultivate rice during rainy season (June-September) and land leftovers fallow aft...
متن کاملBreeding drought tolerant rice for shallow rainfed ecosystem of eastern India
In shallow rainfed rice agro-ecosystems, drought stress can occur at any growth stage and can cause a significant yield reduction. During recent years, some rice varieties possessing tolerance of reproductive-stage drought stress have recently been developed. Tolerance of vegetative-stage drought stress is also required to improve rice productivity in drought-prone regions. In this study, we ev...
متن کاملMethane efflux from rice-based cropping systems under humid tropical conditions of eastern India
Tropical rice paddy is considered to be one of the major anthropogenic source of atmospheric methane (CH4). In a field study spread over the dry and wet seasons of a calendar year, the CH4 emission from upland (oilseed and pulse) crops in the dry season and a succeeding lowland rice (Oryza sativa L.) crop in the wet season was compared with rice–rice rotation in both seasons under flooded condi...
متن کاملManagement of clay soils for rainfed lowland rice-based cropping systems: an overview
The problem of concern in this project is that in the dry season following a lowland rice (Oryza sativa L.) crop, yields of post-rice crops are generally low, despite adequate water commonly being available in the soil pro®le to grow a potentially high yielding dry season (DS) crop without irrigation. Maize (Zea mays L.) yields are as low as 1 Mg haÿ1 or less, soybean (Glycine max L. Merr.) and...
