Not AvailableAn experiment was conducted for two years during 2005-07 using DCS-9 variety to see the effect of source manipulation on yield of different spike orders. Treatments consisted of four defoliation levels (25%, 50%, 75% and 100%) at primary, secondary and tertiary spike initiation stages along with control, with 3 replications in RBD. Primary seed yield reduced with defoliation at primary and secondary spike initiation stages. Secondary, tertiary and quarternary seed yield reduced with defoliation at secondary and tertiary spike initiation stages. Defoliation at primary, secondary and tertiary spike initiation stages resulted in 21, 33 and 26% yield reduction respectively.Not Availabl
