Deriving the different agro meteorological indices under different growing environments for chickpea crop

Abstract

A field experiment entitled “to find out the different agro meteorological indices under different growing environments for chickpea crop” was conducted at the Research and Instructional farm of I.G.K.V., Raipur during rabi 2019-20. The treatments consisting of three Growing Environment (GEs) viz. 15th Nov., 30th Nov. and 15th Dec. and three chickpea varieties viz. Vaibhav, JG -14 and JG -16 were laid out in Factorial RBD with 3 replications. The results found that the agrometeorological indices Accumulated Growing Degree Day (GDDs) at maturity stage were highest (2086) for Vaibhav under 15th Nov. sowing maximum GDDs were observed in 15th Nov. as compared to normal sown crop 30th Nov. and late sown crop on 15th Dec. at maturity stage. The maximum HTUs of (13487) was recorded for variety JG-16 sown on 15th Nov. whereas second highest HTUs of (13189) was recorded for JG-14 in 30th Nov. growing environment and next for Vaibhav (13374) under 15th Dec. sown crop. Similar is trend for PTUs of chickpea varieties under different GEs. At maturity stage highest HUE and RUE is generally observed for normal growing environment. Vaibhav variety is found to be having highest HUE and RUE. It is followed by JG-14 and least value is being observed in JG-16 variety.
