Center has successfully carried out its research activities and consequently, a considerable amount of valuable and meaningful information has been generated through interdisciplinary research. Important aspects on which research has been and being carried out, are mentioned here:
- Development of Ground Water Recharge (Aquifer Storage and Recovery, ASR) technology.
- Development of the Sliding Slab Nakka for the watercourses.
- Development of watercourse pre-cast lining materials and techniques like, lining of watercourses with RCC slabs, single piece lining in trapezoidal or rectangular design.
- Research work to develop special watercourse lining mediums like cement-sand mortar in different ratios and installation of compacted soil-cement cores to reduce seepage losses.
- Determination of appropriate slope gradients for irrigation on different soil textures without affecting water intake uniformity and reducing the cost of levelling.
- Development of Auto-start graduated siphon and a simple flume.
- Reclamation and management of saline-sodic soils using different treatments like, sub soiling to facilitate salt leaching, green manuring, chemical amendments, plantation of various tree species, amendments to saline-sodic groundwater, use of calcium containing N and P fertilizers, integrated use of green manuring and chemical fertilizers.
- Restoration of soil fertility using best fertilizer/manure and development of technology for preventing bad effects of groundwater on soil characteristics and crop yield.
- Determination of salt balance in command areas of two watercourses to trace out the amount of salts added to the root zone via canal irrigation and SCARP tube wells
- Use of recycled drain water for crop production in normal and salt-affected soils.
- Scheduling of irrigation for wheat and maize grown at different depths of groundwater table for effective use of water resources.
- Use of different irrigation methods like border, furrow-ridge, furrow-bed, etc., for getting good crop yield at maximum irrigation efficiency.
- Determination of the economic depth of irrigation water applied to rice at each irrigation.
- Determination of the effect of water stress and adequate time of transplanting in rice.
- Comparison of different sowing methods (transplanting VS direct sowing in lines or broadcast) in rice.
- Determination of the effect of irrigation interval in rice.
- Comparative studies of soil puddling and soil compaction in rice.
- Studies in wheat for determination of the effect of water stress at critical growth stages, to quantify the water requirements based on Cumulative Pan Evaporation (CPE), irrigation scheduling using different ratios of Irrigation Water (IW): CPE.
- Production economics of growing different wheat-lentil associations.
- Water productivity of wheat under different irrigation methods (rain gun, furrow-bed and drip irrigation).
- Genetic response of wheat to irrigation at different levels of crop evapotranspiration (Etc).
- Genetic response of cotton to irrigation at different levels of crop evapotranspiration (Etc).
- Use of zero tillage, its constraints, and its adoption under farmers’ conditions for rice-wheat rotation system.
- Prediction of irrigation schedules with or without rainfall for wheat, sugarcane, barseem, and tobacco crops using climatic data of the observatory of the Center.
- Screening of cotton varieties based on CPE and comparison of different irrigation methods (flat, furrow-bed and furrow-ridge) for water use efficiency.
- Determination of appropriate number of irrigations for gram,lentil and mung beans.
- Development of Four-Row Wheat Bed Planter and promotion of Raised Bed Technology for all major crops viz. cotton, maize, wheat, rice, vegetables, etc.
- Evaluation of furrow size in raised bed technology for wheat water productivity.
- Economics of vegetables production in tunnels under mulch and non-mulch condition.
- Development and testing of locally made mobile power unit for drip irrigation system.
- Development of low-cost low-energy drip irrigation system
