EFFECT OF TIME AND FREQUENCY OF IRRIGATION ON THE GROWTH AND YIELD ATTRIBUTES OF CHICKPEA (Cicer arietinum L.) VARIETIES

Abstract

The present experiment was conducted in the Agricultural Botany field laboratory of Sher-e-Bangla Agricultural University, Sher-e-Bangla Nagar, Dhaka, Bangladesh during rabi season (November 2016 to March, 2017) to study the response of chickpea varieties to different levels of irrigation . In this experiment, the treatment consisted of three chickpea varieties viz. BARI Chola-5, BARI Chola-9 and BARI Chola-7 and four irrigation levels viz. No irrigation, Irrigation after 40 and 50 DAS, Irrigation after 60 and 80 DAS, Irrigation after 50, 70, and 90 DAS. The experiment was laid out in a Randomized Complete Block Design with three replications. The collected data were statistically analyzed for evaluation of the treatment effect. Results showed significant variations among the treatments in respect of majority of the observed parameters. The tallest plant height was obtained from BARI Chola 9. BARI Chola 9 produced maximum number of branch per plant, number of pod per plant, number of seeds per pod, 1000-seed. The highest yield (1.723 t/ha) was recorded in care of BARI Chola-9. The lowest yield was recorded in BARI Chola-5 (1.434 kg/h). Significant influence of different levels of irrigation ware observed on maximum parameters. The tallest plant was recorded with the Irrigation after 60 and 80 DAS. The maximum number of pod per plant (37.39), number of seed per pod (2.28), 1000-seed weight (123.00 g) were produced with the Irrigation after 60 and 80 DAS. The maximum yield of seed per hectare (2.15 t) was obtained from Irrigation after 60 and 80 DAS treatment. The interaction between variety and irrigation was found significant on the all the parameters. The highest yield of seed per hectare (2.52 tones) was obtained from BARI Chola-9 with Irrigation after 60 and 80 DAS treatment combination

The highest yield of stover per hectare 2.62 tones, biological yield per hectare 5.13 tones, harvest index 49.02 % were obtained from BARI Chola-9 with Irrigation after 60 and 80 DAS. treatment combination.
