Abstract:

Field experiment were conducted in Gujarat, India, during the 1999 and 2000 summer seasons, to determine the effect of irrigation schedule, dates of sowing and genotypes on yield, water use efficiency (WUE), water expense efficiency (WEE) and water extraction pattern in cowpea. The cowpea crop sown on 2 March recorded significantly higher seed and haulm yields. Application of irrigation at an IW: CPE ratio of 1.0 recorded significantly higher seed and haulm yields. The GC 4 cultivar performed better than GC 2 and Pusa Falguni. The crop consumed maximum water and also recorded higher WUE and WEE. Application of irrigation at an IW: CPE ratio of 1.0 consumed maximum water, but recorded least WUE and WEE. The GC 4 cultivar consumed maximum water and also recorded maximum WUE and WEE. Late sowing of cowpea cultivars extracted more water from upper soil layer compared to lower soil layer. As IW: CPE ratio increased, extraction from the upper layer increased. The Pusa Falguni cultivar extracted maximum soil moisture from the upper layer.
