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 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 کاملEnhancing 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 کاملEvaluation, Design and Control of Sustainable Horticultural Cropping Systems
As all other human activities, horticulture is accountable for its impact on the resources available, now and in the future, to our societies. The problem is of particular importance in production systems that are often intensive and require high amounts of inputs. To fit with the increasing number of regulations and contracts growers have to respect, tools must be created to evaluate existing ...
متن کاملinvestigation of single-user and multi-user detection methods in mc-cdma systems and comparison of their performances
در این پایان نامه به بررسی روش های آشکارسازی در سیستم های mc-cdma می پردازیم. با توجه به ماهیت آشکارسازی در این سیستم ها، تکنیک های آشکارسازی را می توان به دو دسته ی اصلی تقسیم نمود: آشکارسازی سیگنال ارسالی یک کاربر مطلوب بدون در نظر گرفتن اطلاعاتی در مورد سایر کاربران تداخل کننده که از آن ها به عنوان آشکارساز های تک کاربره یاد می شود و همچنین آشکارسازی سیگنال ارسالی همه ی کاربران فعال موجود در...
