Enhancing Source-Sink Partitioning Efficiency and Productivity of Sesame

Abstract

                                A field experiment was conducted to study the effect of nipping and foliar spray of growth regulator on the growth and yield of sesame during Kharif 2016 at Regional Research Station, Vridhachalam. The experiment was laid out in randomized block design with seven treatments encompassing terminal nipping and salicylic acid spray at 30 and 45 DAS, alone and in combination which were replicated thrice. The results of the experiments revealed that the terminal nipping along with a foliar spray of 100 ppm salicylic acid at 30 DAS recorded higher leaf area index (1.54), number of branches per plant (9.7), number of capsules per plant (109.5), and higher sesame seed yield of 930 kg ha-1.

Key words : Sesame, nipping, plant growth regulator, salicylic acid.
