Abstract

A field experiment was conducted during the summer season of 1997 and 1998 to study the effect of biofertilizer (phosfert, bioplin and vitormone) and growth regulator (protein hydrolysate) on growth and productivity of sesame (Sesamum indicum L.). Use of biofertilizer or growth regulator alone showed significant improvement in plant height and number of branches/plant. It tended to increase the yield components such as number of capsules/plant, number of seeds/capsule and 1000-seed weight and so also the seed yield over those obtained without having any biofertilizer or growth regulator treatment (control), but the differences were not significant. Combined use of biofertilizer and growth regulator, however, recorded further improvement in growth attributes, which in turn resulted in significant increase in the entire above yield components and ultimately the seed yield over no application. Use of biofertilizer and growth reg'ulator together brought about 32 to 34.6% yield increase over control.
