Effect of plant growth regulators on yield and yield attributing characteristics of mango (Mangifera indica L) cv. Dashehari

Chandramukhi Sahu and Damendra Kumar Sahu

The present investigation entitled “Effect of plant growth regulators on yield and yield attributing characteristics of mango (Mangifera indica L.) cv. Dashehari” was carried out at the instructional Farm, Dept. of Horticulture, College of Agriculture, IGKV, Raipur (C.G) during the year 2017-18 employing Randomized Block Design with three replications. Three levels of NAA i.e., 15, 25 and 35 ppm, three levels of GA3 i.e. 15, 25 and 35 ppm and three levels of 2, 4-D i.e. 15, 25 and 35 ppm were sprayed at pea and marble stage of fruit development. All the treatments significantly influenced the number of fruits retained at pea, marble and harvesting stage of fruit growth and development as compared to the control. Foliar application of 35 ppm GA3 at pea and marble stage of fruit development increased number of fruits (880.49) as well as total yield (135.46 kg/plant). Physical characters of fruit viz., Fruit Length (11.65cm) and width of fruits (6.82cm), average fruit weight (177.84g), volume (173.63g) and pulp weight (130.41g) were also improved with the foliar application of 35 ppm GA3. While, stone weight (25.39g) and peel weight (19.02g) was reduced with the foliar application of 35 ppm NAA and 25 ppm foliar application of 2, 4-D. Among the different concentrations of plant growth regulators; the foliar application of 35 ppm NAA, 35 ppm GA3, 35 ppm 2, 4-D were found to be optimum concentration by which yield and yield attributing characteristics of fruits can be significantly influenced.
