Abstract:
A field experiment entitled “Identification of weather parameters affecting the yield of chickpea under different growing environments” was conducted at the Research and Instructional farm of I.G.K.V., Raipur during rabi 2019-20. The treatments consisting of three growing environments viz. 15th November, 30th November and 15th December and three varieties of chickpea viz. Vaibhav, JG-14 and JG-16 were laid out in Factorial RBD with three replications. Correlations studies between yield kg ha-1 with weather parameters were done. Significant negative correlation of Tmin (P-II) and RF (P-VI) stage for Vaibhav variety and significant positive correlation in the BSS (P-VI) was found. Significant negative correlation of Tmin in the (P-II and P-I), RF (P-VI), RH-I (P-VI), RH-II (P-IV and P-V) for JG-14 variety was found. Significant negative correlation in Tmin in the (P-II), RF (P-VI), RH-I (P-VI) and significant positive correlation for BSS in P-VI stage for JG-16 variety was found. Chickpea is sensitive to high (maximum daily temperature >35° C) as well as low (mean of maximum and minimum daily temperatures <15° C) temperature at reproductive stage. Both extreme of temperature lead to flower drop and reduced pod set. This resulted in significant reduction of seed yield due to untimely rain and lack of proper temperature as the crop started blooming.
