Enhancing economic water productivity under on farm reservoirs in diversified rainfed cropping systems
A long term study was done to assess the impact of on farm reservoirs (OFR) on oil seedand cereal based cropping systems with vegetables (okra, tomato and carrot) in semi-aridalfisol of southern Telangana region. Two supplemental irrigation (SI) depths (30 and 50 mm)from OFR with raingun system were studied for assessing the water productivity andprofitability of the technology in these croppin...
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...
متن کاملCrop 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 کاملEconomic Evaluation of Cereal Cropping Systems under Semiarid Conditions: Minimum Input, Organic and Conventional
Cropping systems like organic farming, selling products at a higher price and promoting environmental sustainability by reducing fertilizer and pesticides, can be more profitable than conventional systems. An economic evaluation of three cropping systems in a seven year period experiment was performed, using a common rotation (fallow-barley-vetch-durum wheat) in a semi-arid rainfed field of Spa...
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...
