Studies on Effect of Nutrient and Irrigation Levels on Growth and Yield Parameters, and on Kapas Yield of Cotton in Southern Dry Zone of Karnataka
Journal Title: International Journal of Agricultural Science and Research (IJASR) - Year 2017, Vol 7, Issue 4
Abstract
A field experiment was conducted during kharif season of 2016 at Zonal Agricultural Research Station, V. C. Farm, Mandya. The experiment was laid out under split plot design with 3 irrigation levels (0.6, 0.8 and 1.0 IW/CPE ratios) as main plots and 3 nutrient levels (75, 100 and 125% RDF-150:75:75 kg NPK/ha) as sub plots, and these treatments were replicated thrice. Irrigation at 0.8 IW/CPE ratio and nutrient level of 100 per cent RDF have significantly recorded higher growth and yield parameters viz, plant height, monopodial and sympodial branches, leaf area, LAI, dry matter production, stick yield and lint yield along with the kapas yield (22.94 and 22.49 q ha-1, respectively) as compared to irrigation at 0.6 IW/CPE ratio and nutrient level of 75 per cent RDF, respectively. But, they were at par with irrigation at 1.0 IW/CPE ratio and nutrient level of 125 per cent RDF, respectively and found optimum in enhancing the cotton growth and kapas yield.
