| dc.description.abstract | A field experiment was conducted at Main Research Station, University of Agricultural Sciences, Dharwad on medium black soil to study the "Response of chickpea genotypes to irrigation schedules and NAA spray in Vertisols of northern Karnataka" during rabi 1999. The experiment was laidout in split plot design with three replications. There were 18 treatment combinations consisting of 3 irrigation schedules (0.4, 0.6 and 0.8 IW/CPE ratios) as main plots, and 2 genotypes {desi variety Annegeri-1 and kabuli variety ICCV-2) and 3 NAA spray treatments (no spray, 20 ppm spray and 30 ppm spray) as sub-plots. Irrigation scheduling at 0.6 IW/CPE ratio recorded significantly higher seed yield (7.9 and 17.6%) over 0.8 and 0.4 IW/CPE ratio, respectively. Among the genotypes, desi variety-Annegeri-1 outyielded kabuli variety-ICCV-2 by 27 per cent. The spray of NAA @ 20 ppm increased the seed yield of chickpea significantly over 30 ppm spray and no spray. This was the consequent effect of significantly improved growth and yield parameters. Irrigation scheduling at 0.6 IW/CPE ratio, desi variety-Annegeri-1 and 20 ppm NAA spray recorded higher water use efficiency. Irrigation scheduling at 0.6 IW/CPE ratio with 20 ppm NAA spray to desi variety recorded higher net returns and B:C ratio. Based on the results it could be concluded that scheduling of irrigation at 0.6 IW/CPE ratio to desi variety-Annegeri-1 with 20 ppm NAA spray was economically feasible for realising higher seed yield and net returns in chickpea in vertisols of Northern Karnataka. | en_US |
