A long term experiment was conducted to Effect of pruning with paclobutrazol application for Growth, Yield and Quality of Mango (Mangifera indica L.) C.V. Amrapali was conducted during 2007-08 to 2014-15at Fruit Research Station Kuthulia farm, College of Agriculture, Rewa Under All India Coordinated Research Project on subtropical fruits. The experiment was laid out in Randomized Block Design (RBD) comprising 10 treatments, which were replicated thrice. The treatments were comprised of 3 pruning methods namely M0: No pruning, M1: 10cm heading back to terminal shoots, M2: 10cm heading back to terminal shoots, and 2 levels Paclobutrazol treatments i.e. P0: without paclobutrazol and P1: standard dose of paclobutrazol. The results indicate that various pruning of high density planting level and use of paclobutrazol exhibited significant effect on canopy, yield and quality of the fruits. The maximum tree height (7.10 m, ) were observed in treatment M2F2 T2 “20 cm heading back to terminal shoots during rest period before the emergence of new growth biannual time” tree spread from E-W and N-S (6.20m and 6.17m), were observed with the treatments M0F0 T0 control without paclobutrazole application (Table 1a), The higher fruit weight and pulp percentage (347.50 g and 72.30), were observed with the treatment M2F2T1: “20 cm heading back to terminal shoots during rest period before the emergence of new growth Annual time” The maximum Pulp percentage was recorded (71.85%) in M2F1T220 cm heading back to terminal shoots Immediately after fruit harvest (June-July) Biannual time. The Maximum Total Soluble Solid (TSS) and acidity percentage (21.87oB and 0.30) were observed with the treatment M0F0T0 control with paclobutrazol application. The pooled mean of 8 years data clearly indicated that fruit yield tree-1 and yield ha-1 (53.27 and 213.08 qt.) have been registered with the treatment of M0F0T0:Control with paclobutrazol application. The benefit cost ratio was also found higher with this treatment 2.6 (hectare basis) has been observed with the treatment of No Pruning with Paclobutrazol application.
