The present field experiment entitled “Effect of high density planting systems on growth of mango (Mangifera indica L) var. Amrapali” was carried out at the horticulture farm of Sam Higginbottom University of Agriculture Technology and Sciences, Prayagraj during the year 2023 to study the performance of different varieties for vegetative growth, reproductive growth, fruit physical parameters, yield parameters, quality of fruits and organoleptic parameters under high density planting. The experiment comprised of five treatments with six replications in randomized block design. The result revealed that, Amrapali mango plants recorded the maximum plant height (2.32 m), number of tertiary leaves per plant (24.99), spread of plant (N-S) and E-W (216.58 and 206.63 cm), Stem girth (6.86 cm), total number of panicle per plant at initial flowering (9.73), length of panicle (40.22 cm), width of panicle (28.20cm), fruit set (7.66%), fruit weight (386 g), fruit length (13.38 cm), fruit width (7.92 cm), number of fruits per plant (48.10), yield per plant (747.78 g), yield per plant (10.15 kg), and number of fruits yield per ha (16.91 t) were recorded in plants in the treatment T6. The quality parameters mango plants TSS (16.23 °B), reducing sugar (6.22), non-reducing sugar (15.92) were recorded in plants in the treatment T6. The maximum cost of cultivation (Rs.), gross return, net return and benefit cost ratio was recorded in the Treatment T6 with cost of cultivation Rs.71970, Gross return Rs. 338200 and Net Return Rs 266230 and Benefit cost ratio Rs 3.70. The application of T6 (R.D.F + F.Y.M) was found to best in terms of growth parameter, quality and found the best treatment on basis off economics of mango.
