The rainout shelter is used for screening germplasm and breeding materials for drought tolerance. It tests for drought tolerance under real soil and weather conditions, to see how roots of dry-land crops perform during arid periods within growing seasons. The shelter includes a lysimeter facility with 2,800 PVC tubes filled with soil to measure plant water use in outdoor conditions and serve as a bridge between field-based and laboratory-based research on water consumption and grain yield.
ICRISAT is an UN-affiliated crop research institute that seeks to increase the yield of food crops of small-scale farmers in dry tropical regions with improved genetics and farm techniques. Their primary research facilities are near Hyderabad, India, with satellite research facilities in various African countries. ICRISAT conducts research solely on sorghum, millet, chickpea, pigeon pea, and peanut, which are key subsistence crops for non-irrigated farmland in Africa and S. Asia, and maintains a gene bank with over 120,000 varieties.
