Studies were initiated to regulate the leaf senescence in early maturing cultivar of greengram. Co 3 during monsoon 1983. Benzyl adenine (BA) was employed to retard the leaf senescence in the cultivar. The foliar spray of benzyl adenine was given at peak flowering phase. The study has brought out that Benzyl adenine spray at peak flowering has, considerably delayed the senescence in early type which was associated with increased leaf chlorophyll content and photosynthetic rate and decreased soluble. nitrogen and reducing sugar contents. The number of pods per plant, the total dry matter production, pod yield and seed yield were increased with the level of concen-. tration in the cultivar. A marginal increase in harvest index was obtained in the culti var. In general, the benzyl adenine spray was found to retard the leaf senescence in the early maturing greengram cultivar.
