Effect of sowing windows on yield, economics and growing degree days on varieties of green gram (Vigna radiata L.)

Abstract

Green gram (Vigna radiata L.) is a short day plant and generally requires fairly hot conditions for its optimum growth and yield. Crop growth and development are closely related with energy requirement parameter such as growing degree days (GDD) which ultimately affect yield and economics. Therefore, experiment was conducted on effect of sowing windows on yield, economics and growing degree days on varieties of green gram (Vigna radiata L.) during kharif-2023 at Agronomy farm, College of Agriculture, Nagpur. The experiment was laid out in split plot design with three sowing windows i.e. 26th MW, 27th MW and 28th MW as main plot treatments and three varieties i.e. PKV Green Gold, PKV Moong-8802 and Kopergaon as sub-plot treatments and replicated thrice with spacing of 30 cm x 10 cm. Other operations were carried out as per recommendations. Results revealed that, 26th MW produces significantly highest grain and straw yield, gross monetary returns, net monetary returns, B:C ratio and accumulated higher GDD as compared to 27th and 28th MW. In case of varieties PKV Green Gold produces highest grain and straw yield, gross monetary returns, net monetary returns, B:C ratio and accumulated higher GDD as compared to PKV Moong-8802 and Kopergaon.
