EVALUATION OF PHYSIOLOGICAL EFFICIENCY AND YIELD POTENTIAL OF RAGI GENOTYPES UNDER IMPOSED MOISTURE STRESS CONDITONS

Abstract

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.
