World Bank Assisted Watershed
Development Project
Gulbarga
Yadgiri
Gadag
The project will be implemented in
7 districts, identified by the WDD
based on land and water
resources and socio-economic
conditions.
Koppal
Davanagere
The project will be covering 63
sub-watersheds, which includes
630 micro-watersheds, covering
an area of over 315,000 ha. ,
benefiting farm households of
about 200,000 in the state.

Mean Soil Chemical characteristics of Gulbarga District
•
Agro-climatic conditions
•
Both the districts fall under North-Eastern dry zone
•
Soils vary from deep (2-2.6 m) to shallow (0.6 – 1.0 m)
with small portion of lateritic soil
•
The ground elevation ranges from 330 m to 625 m
Research Priorities
•
To improve rainwater-use efficiency under rained
agriculture through integrated conservation approach
•
Deriving the options to balance and manage N,P and K
and micronutrients through site specific management.
•
Development of decision support tools for site selection
and for design of soil and water conservation measures
reinforcing with traditional and indigenous know-how
•
Decision support system to take up sustainable cropping
pattern and crop production system based on land
capability classification for each micro-watershed
•
Adoption of genomics derived drought resistant both
Khariff and rabi sorghum varieties and characterization of
specific races of sorghum, green gram, sesamame,
millets and linseed.
•
Design, development and construction of location
specific water harvesting / ground water recharging
structures considering geo-hydrological characteristics
and developing mechanism (solar energy based pump) of
reusing for protective irrigation efficiently.
•
Increasing crop productivity through crop diversification
with inclusion of high value crops
•
To establish silt monitoring station and to monitor runoff and
sediment yield at out let of each representative microwatershed for assessing its hydrologic responses and to help
transfer data from gauged to ungauged similar watersheds.
•
Assessment of Post harvest losses and Strategies for
Prevention of losses in Major agricultural and horticultural
Commodities
