A field experiment was conducted during kharif, 2015 at Agricultural Research station (Millets), ANGRAU, Tirupati. Field experiment was laid out in factorial randomized block design, replicated thrice with two ma in treatments i.e. adequately irri-gated, rainfed and ten sub treatments (genotypes). Growth and physiological traits viz. plant height, dry matter accumulation, leaf area index (LAI), harvest index and grain yield significantly reduced under rainfed conditions compared to irrigated control. Among the genotypes, the three pre release genotypes viz., BR-36, PPR-1012 and PPR-2773 were under ranifed as well as irrigated conditions recorded significantly higher physiological efficiency in terms of LAI, total plant drymatter along with higher HI and yield. It denotes their efficiency in performing under drought condition. Hima (released variety) recorded low performance and it may not fit for cultivation in rain fed areas.
