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 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 کاملEffect of Tillage Practices on Soil Properties and Crop Productivity in Wheat-Mungbean-Rice Cropping System under Subtropical Climatic Conditions
This study was conducted to know cropping cycles required to improve OM status in soil and to investigate the effects of medium-term tillage practices on soil properties and crop yields in Grey Terrace soil of Bangladesh under wheat-mungbean-T. aman cropping system. Four different tillage practices, namely, zero tillage (ZT), minimum tillage (MT), conventional tillage (CT), and deep tillage (DT...
متن کاملSustaining Productivity in Rainfed Agriculture System
Sustaining and enhancing agriculture productivity has been recognized as one of the key pathways of reducing and eliminating hunger, poverty and malnutrition. Agricultural sector is regarded as the key component of the economies of many developing nations, including India. Globally, agriculture accounts for a large share of GDP, it employs a significant proportion of the labour force, represent...
متن کاملEffect of crop residue and nitrogen levels in yield and yield attributing traits of rice under Rice-Wheat Cropping System
A 3- years (2015, 2016 and 2017) field study was carried out at National Wheat Research Program, Bhirahawa, Rupandehi, Nepal to evaluate the influence of crop residues and nitrogen levels on rice. The experiment was conducted in split plot design with three replications. Main plots were two crop residue levels (with crop residues of 30 cm wheat stubble and without crop residues) and sub plots c...
