A lysimeter facility with a rain-out shelter at the ICAR-Indian Institute of Millets Research, Hyderabad to screen the genotypes and evaluate their performance under drought conditions. The lysimeter method (long PVC tubes of 2.0 m length and 25 cm diameter) enabled to closely monitor and record the plant water use patterns and biomass accumulation of the tested genotypes from the early growth stages all the way through to maturity. This detailed data collection and analysis approach provided valuable insights into the drought response mechanisms and adaptive strategies of the different genotypes under investigation.
