Abstract

Two cultivars, viz, Pb: Til No, and TC 25 of sesame (Sesamum indicum L.)were used to study the effect of Plant density on yield and yield components. Five spacings i, e.. 30x0, 30x7.5, 30x15, 30x22.5, and 30x30cm. were used. Cultivars differed significantly with respect to flowering days, maturity days and capsules on main shoot whereas plant density produced highly significant effects on flowering days, maturity days, branches and yield, Linear and non-linear components were significant for all characters except plant height, pods on main shoot and yield. Linear relationship was observed for flowering days, maturity days; branches whereas linear to non-linear relationship was noticed for pods on main shoot, pods per plant and yield with increase in spacing fiom plant to alant. Highest yield was obtained, at 30x15cm, spacing. This spacing can be used with advantage for branched varieties of sesame in Punjab for maximum grain yield.
