Crop growth regulation and detopping in summer moong for contemporizing maturity

Abstract

A field study entitled “Crop growth regulation and detopping in summer green gram for contemporizing maturity" was conducted at GSSDGS Khalsa College, Patiala, Punjab during the summer season of 2017. The experiment was conducted in a randomized complete block design comprising of eight treatments with three replications. The treatments included MC (mepiquat chloride) @ 200 ppm (35 DAS), MC @ 200 ppm (35 and 45 DAS), MC @ 250 ppm (35 DAS), MC @ 250 ppm (35 and 45 DAS), MC @ 300 ppm (35 DAS), MC @ 350 ppm (35 and 45 DAS), detopping and control. Yield attributes such as plant height and dry weight, improved significantly with MC @ 250 ppm (35 and 45 DAS) followed by control. The highest harvest index (20.17%) was recorded in MC @ 250 ppm (35 and 45 DAS) along with the highest B: C ratio.
