The work was conducted with the purpose of to evaluate the effect of moisture stress on physiological and yield
parameters in ten ragi genotypes viz. (GP-3, GP-23, GP-24, GP-25, GP-104, GP-111, GP-149, GP-153 and
GP-160). The experiment was conducted in factorial randomized block design with three replications. Moisture
stress was imposed from panicle initiation to grain filling stage i.e. (35-60 DAT). Moisture stress reduced the all
physiological and yield parameters. The genotype gp-153 performed better than other genotypes, it recorded
higher CGR (16.75 g m-2 day-1), higher LAI (2.15), higher LAD (33.71 cm2 g-1) and higher grain yield (2560.0 Kg
ha-1), higher straw yield (6966.67 Kg ha-1) and higher harvest index (26.80) followed by GP-111. Hence these
genotypes can perform better under moisture stress conditions and are suitable for rain fed situations.
