Abstract
Present study was carried out to determine the yield and growth of sesame (sesamum indicum L.) variety S-9 under foliar nitrogen doses atdifferent application times at Sindh Agriculture University Tandojam. The experiment had been placed in a Randomized Complete Block Designwith net plot size (6m2) with three replication. The sesame variety S-9 was used and checked under various foliar nitrogen doses at differentapplication time treatments i.e. T1= N @ 00 kg ha-1 (control), T2= N @ 0.5 kg ha-1 (30 DAS), T3= N @ 0.5 kg ha-1 (45 DAS), T4= N @ 0.5 kg ha-1 (60 DAS), T5= N @ 1.0 kg ha-1 (30 DAS), T6= N @ 1.0 kg ha-1 (45 DAS), T7= N @ 1.0 kg ha-1 (60 DAS), T8= N @ 1.5 kg ha-1 (30 DAS), T9= N @ 1.5 kg ha-1 (45 DAS), T10= N @ 1.5 kg ha-1 (60 DAS). The results revealed that maximum values for sesame traits under study were i.e. Plant height (122.38 cm), Branches plant-1 (34.45), Capsules plant-1 (194.60), capsule length (2.65cm), Seeds capsules-1 (56.3), Seed wt plant-1 (76.31 g), Seed index (5.69, 1000 seed wt g), Seed yield (1233.3 kg ha-1), Harvest index (11.12%), were recorded under treatment T10= N @ 1.5 kg ha-1 (60 DAS), whereas; minimum values for various sesame traits i.e. Plant height (80.57 cm), Branches plant-1 (15.47), Capsules plant-1 (130.31), Capsules length (1.30 cm), Seeds capsules-1 (30.5), Seed wt plant-1 (50.57 g), Seed index (3.34, 1000 seed wt g), Seed yield (711.7 kg ha-1), Harvest index (6.23%), incontrol treatment where no foliar nitrogen doses was applied. It was concluded that growth and yield increased at T10= N @ 1.5 kg ha-1 (60DAS) and thus recommended for better performance and yield of sesame crop.
