The agriculture in low rainfall areas of eastern Rajasthan, India is characterized by high risks from drought, degraded natural resources and pervasive poverty, food insecurity malnutrition. In this region, water the main limiting factor for upgrading rainfed agriculture. For such integrated watershed management recognized as a potential approach growth rehabilitation fragile lands. At Gokulpura-Goverdhanpura village Bundi an project was implemented using holistic systems approach. This...
Many environmental benefits result from watershed interventions in the semi-arid tropics. Environmental may be defined as condition and process through which ecosystems sustain fulfill human life, including provision of food other goods. The spillover effects these range an increase household welfare to ecosystem sustainability. An attempt is made this paper assess context Indian Semi-arid tropics using primary data collected two micro watersheds (Rajasamadhiyala Shekta watersheds). Results...
Long-term experiments can be used to assess management induced changes in soil properties and sustainability of the system terms productivity. Such data are scanty, especially semi-arid tropics (SAT) region. A long-term experiment established 1976 at ICRISAT India on Vertisols with two treatments; improved (IM), comprising semi-permanent broadbed furrow (BBF) landform minimum tillage cropping practices; traditional (TM) keeping land fallow during rainy season sowing flat post-rainy...
ABSTRACT Amodified Soil Conservation Service (SCS) runoff model and a soil moisture accounting procedure were used to simulate for small watersheds. The validity of the tested using hydrological data collected from Vertisol watersheds at ICRISAT Center in India. agreement between measured simulated daily, monthly, annual was good. root mean square error values annual, daily watershed 5.2, 3.1, 1.6 mm, respectively. modified quite accurately high, low as well normal rainfall years semi-arid...
Aims: As climate change related rainfall and temperature variability is being increasingly experienced in the SAT regions, we assessed mitigation adaptation potential of Conservation Agriculture (CA) by studying effects minimum tillage (MT) residue management practices on rain water use efficiency (RWUE), soil moisture, runoff, energy carbon dioxide emission two maize-legume cropping systems.Study Design: The experiment was laid out split-split plot design with four replications.
In the semi-arid tropics (SAT),33% areas are occupied by Alfisols and related soils. SAT these soils have low structural stability thereby tend to form seal crusts at surface. Due this a large proportion of rain that falls on during early part rainy season,is normally lost as runoff thus causing high soil loss well moisture stress crops. Two tillage studies were conducted first plot scale (320 m2) 1991-95 second small watershed (1.45 ha) 2007-10,at ICRISAT research station,Hyderabad,India....
