A field experiment was carried out during 2009-11 on a sandy loam soil of IARI, New Delhi on wheat with four levels of irrigation (rainfed, irrigations to replenish 30, 60 and 100% moisture deficit from field capacity) as main plot factors and four levels of nitrogen (0, 30, 60 and 120 kg N/ha) as subplot factors in a split plot design. The soil moisture storage in the profile showed inverse re...

IWRM should include the integration of management instruments towards intersectoral efficient water allocation. A platform linking economywide and network-based models, available from a Spatial Decision Support System (SDSS), was used to analyze allocation decisions in 4-interlinked basins Northeastern Brazil during period scarcity. The SDSS can integrate issues considering hydrologic socioecon...

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...

Environmental and economic problems in water bodies can result from the lack of understanding of these processes. For example, sediment moving through a watershed transports nutrients and pollutants that can damage aquatic habitat and reduce soil productivity in agricultural areas. In addition, sediment movement and deposition in streams can increase the cost to maintain navigation and interfer...

Of the several mechanisms that can bring about efficient resource use, the most widelyapplicable one is intercropping systems that can make better use of resources. The aim of thisstudy was to evaluate resource capture and resource use efficiency in transgenic cotton-peanutintercropping system and in their respective sole crops with using 25-50% substitution ofrecommended dose of nitrogen (RDN)...

The Riacho Fundo qualitative model, a product of the Brazilian case study run by the Univeristy of Brasilia in Naturnet project, was evaluated by stakeholders. The Riacho Fundo basin is located near Brasilia, the new capital, and changes in land use are held responsible for major changes in the area, including deforestation, erosion, loss of biodiversity and water resources, and decrease in eco...

The Green Revolution in Haryana has achieved much progress in agricultural productivity but at the cost of land and water degradation. Intensive agriculture during the Green Revolution period has brought continuous environmental degradation, particularly of soil, vegetation and water resources due to the use of high doses of fertilisers and pesticides. The adaptation of various modern agricultu...

Available fresh water resources are subjected to an ever-increasing pressure due to extensive agricultural water demand for irrigated lands. A long-term perspective in shortage of fresh water resources, especially in arid and semi-arid area, highlights an urgent solution for innovative irrigation strategy and agricultural water management. This paper is a review on the wide applications of the ...
