Effect of Plant Growth Regulators and Fertigation on Growth of Pomegranate cv. Sinduri under High Density Planting System in Sub-humid Plains of South Eastern Rajasthan
Keywords:Fertigation, High Density Planting, Plant Growth, Pomegranate
AbstractAn investigation was carried out under the Department of Fruit Science, College of Horticulture and Forestry, Jhalawar. The experiment was conducted in the pomegranate orchard established under high density planting system at the Krishi Vigyan Kendra, Jhalawar in the near vicinity of the college during July 2018 to December 2018 and again during July 2019 to December 2019. The experiment was laid out in Factorial Randomized Block Design and experiment comprised of 27 treatment combinations consisting of plant growth regulators levels (NAA 0, 50 and 100 ppm and ethrel 0, 150 and 250 ppm) and fertigation levels (0, 75 and 100% recommended dose of fertilizers). Results revealed that maximum mean per cent increase in plant height (10.34), plant spread viz., East-West (7.01) and North-South (6.62), canopy volume (25.87) and leaf area (19.51 cm2) was recorded under F2 (fertigation 100% recommended dose of fertilizers). However, interaction effect of NAA, ethrel and fertigation were found to be relatively higher to their individual effect. In interaction effect maximum mean per cent increase in plant height (13.28), plant spread viz., East-West (8.03) and North-South (7.71), canopy volume (31.72) and leaf area (23.55 cm2) was recorded under N2E1F2 (100 ppm NAA + 150 ppm ethrel + 100% RDF through fertigation).
