RESPONSE OF CHICKPEA (Cicer arietinum L.) TO INTEGRATED NITROGEN AND IRRIGATION MANAGEMENT

Abstract

An experiment was conducted at Shcr-c-Bangla Agricultural University farm. Dhaka to study the response of chickpea (Cicer arietinurn 14 cv. BARI chhola-5 to integrated nitrogen and irrigation management during the period from November 2006 to March 2007. 'l'hc trial comprised often treatments as T1 = no fenilizr and no irrigation (control), 12 = 20 kg N hi' as basal without irrigation. 13 = 20 kg N ha' as basal with one irrigation at flower initiation stage. T4 = 30 kg N hi' as basal without irrigation , T5 = 30 kg N hi' as basal with one irrigation at flower initiation stage. T (, = 40 kg N hi' as basal without irrigation, T 7 = 40 kg N hi' as basal with one irrigation at flower initiation stage, T = 10 kg N hi' as basal and 10 kg N hi' as split with one irrigation at flower initiation stage, 1 9 = 15 kg N hi' as basal and 15 kg N ha1 as split with one irrigation at flower initiation stage and ho = 20 kg N ha 1 as basal and 20 kg N ha 1 as split with one irrigation at flower initiation stage. N fertilization with irrigation management generally increased yield and yield components on chickpea. An application of 20 kg N ha 4 as basal and 20 kg N hi' as split application with one irrigation at flower initiation stage (55 DAS) of chickpea tended to produce better performance and gave higher yield. Plants grown without nitrogen fertilizer and irrigation (control) gave the lowest yield.
