Abstract:

Field experiments were conducted during the year 2013 and 2014 under ultra high density planting mango at research and development farm of Jain Irrigation Systems Limited, Udumalpet with four years of mango varieties viz., Alphonso, Himampasand, and Banganapalli trees were selected for the study. The spacing of the grafts was 3mx2m with a plot size of 4x8m2 comprising a population of 1667plant / hac. The experiment was laid out in split plot design with three mango varieties in the main plot and micronutrients in sub plot treated with seven treatments. Three treatments were treated as foliar application and three treatments were applied as soil application through drip system and remaining one treatment was treated as control. The result on the highest tree height in Banganapalli, stem girth in (V2) Himampasand and canopy spread in Banganapalli (V3). Among the treatments, soil application of 0.1% boric acid through drip significantly performed better than the other treatment in both the year of experimentation. Banganapalli (V3) recorded the highest chlorophyll content, soluble protein content and total phenol content; whereas Himampasand recorded the highest activity of nitrate reductase and IAA oxidase. Banganapalli performed better than the other varieties in respect of yield and other important yield components in both 2013 and 2014. 0.1 percent Boric Acid (M2) registered significantly higher number of panicle per tree, panicle length, fruit set (%), fruit girth, fruit length and fruit volume and also the number of fruits per tree. These yield components ultimately resulted in higher fruit yield than the other varieties and treatments. Himampasand recorded the highest TSS (OBrix), total sugars, reducing and non reducing sugars. Alphonso recorded higher ascorbic acid total carotenoid and titrable acidity content than the other varieties. Boron at 0.1% as boric acid applied through drip fertigation significantly recorded the highest TSS (OBrix), total soluble sugars, reducing and non reducing sugars, vitamin C and total carotenoid content. Banganapalli recorded the highest nitrogen phosphorus and potassium, boron, zinc and iron content as compared to the other varieties Alphonso grown field recorded highest available nitrogen, phosphorus and potassium content than the other varieties. The soil available micronutrients viz., boron, zinc and iron were found to the high in M2 M4 and M6 respectively. The highest net return and B:C ratio was registered with Banganapalli in M2.
