The study on “Effect of mepiquat chloride and detopping on growth and production of green gram (Vigna radiata L. Wilczek) under vertisols of Punjab” was conducted during summer season of 2017 at the Agricultural Campus for research and advanced studies in Dhablan, Punjab. The field experiment comprising 8 treatments viz., control and 7 growth retardant treatments The result revealed that the grain yield obtained with application of MC @ 250 ppm at 35 and 45 DAS (10.22 q ha-1 ) was significantly higher than control (6.35 q ha-1 ). Various growth and yield attributes dry weight, number of pods plant-1 (8.12) number of branches plant-1 (9.00) were also significantly higher with MC @ 250 ppm (35 and 45 DAS) as compared to control. All treatments resulted in significant reduction in plant height as compare to control. The experimental results revealed that application of plant growth regulator (MC) is an effective management strategy to increase the yield of green gram crop in terms of yield.
