Response of sesame (Sesamum indicum L.) to growth regulator under dry farming condition

A field experiment was conducted during the kharif season of 2011 and 2014 to study the response of sesame (Sesamum indicum L.) to plant growth regulators. The experiment was conducted in Randomized Block Design with ten treatments and replicated thrice. Among the different treatments T5 (IAA @ 100 ppm at flowering has recorded maximum value for plan height (131.8 cm) and maximum number of capsules per plant at 70 DAS (55.5). The significantly highest 1000 seed weight (3.38 g) of sesame was recorded due to spraying of IAA @ 100 ppm at flowering + capsules formation stage(T7) followed by T5 (IAA @ 100 ppm at flowering stage. The significantly highest harvest index (25.8) was noted under T3 Gibberellic Acid (GA3 -100 ppm) at capsules formation stage. On the bases of pooled results, the significantly highest seed (947 kg ha-1 ), stalk (2810 kg ha-1 ) and biological yield (3757 kg ha-1 ) were obtained due to foliar spraying of IAA @ 100 ppm at flowering and capsule formation stage (T7) and statically at par with T5 and T6. | Response of sesame Sesamum indicum L. to growth regulator under dry farming condition
