Effect of maleic hydrazide on inducing dormancy in green gram (Vigna radiata L.)

Abstract

The search for investigation of non conventional methods of inducing dormancy in green gram to save and retain the quality and quantity of produce against the field sprouting are of greater importance. There are some chemicals which are capable of altering seed dormancy. Foliar application of maleic hydrazide at different growth stages help in altering dormancy in seed. In present investigation, two genotypes viz., Vaibhav and Kopergaon-1 were sprayed with five concentration of Maleic Hydrazide at 1000, 2000, 3000, 4000 and 5000 ppm (along with control) at two stages of crop growth i.e. 40 and 50 DAS. The induction of dormancy was tested by germination test conducted at 5 days interval immediately after harvest. The study revealed that irrespective of varieties maleic hydrazide sprayed at 1000 ppm was most effective for induction of dormancy up to 40 days.
