Abstract
A field experiment was conducted at Pulses and Oilseeds Research Sub-Station, Beldanga,
Murshidabad, West Bengal to study the effect of nipping on growth, productivity and economics
of summer sesame. Among the four plant density levels, 3.3 lakhs plant ha-1 (30 x10 cm) was
superior to other three levels in respect of plant height and number of seeds per capsules
resulting in higher seed yield of sesame. Nipping of terminal bud at 25 DAS significantly
increased the branches, number of capsules, seed yield (13 and 10%), net return and benefit
cost ratio of sesame over no nipping in both the years of study. The increase in yield by
nipping at 25 DAS was more at lower plant density level than that with higher one over no
nipping
Key words : Sesame, nipping, plant geometry, growth, yield, economics
