was conducted for two consecutive years during 2005-07 using DCS-9 variety. Treatments consisted
of four defoliation levels (25%, 50%, 75% and 100%) at primary, secondary and tertiary spike initiation
stages on entire plant along with control, with 3 replications in RBD. With increase in percent defoliation
at any stage there was reduction in stem, leaf, capsule dry weight which resulted in significant reduction
in total dry matter. There was compensation in growth only up to 25% defoliation at any stage. Only
primary seed yield was affected with defoliation at primary spike initiation stage, but with secondary
stage defoliation, yield of all order branches was affected. Secondary, tertiary and quarternary seed yield
was affected with defoliation at tertiary stage. Yield of one order decreased with >25% defoliation at
that order and >50% defoliation at next lower or higher order spikes.Not Availabl
