Effect of high density planting systems on growth, yield and quality of mango (Mangifera indica L) cv. Amrapali after rejuvenation

Abstract

Mango trees grown under high density planting system show a gradual decline in yield after 10-11 years due to overcrowding of canopies. It results in poor utilization of available resources and ultimately low productivity and profitability. So, to maximize the yield per unit area an experiment was conducted on an old senile, rejuvenated high density orchard during the year 2011-12 under experimental area of BAU, Sabour with objective to find out the effect of high density planting systems on growth, yield and quality of mango cv. Amrapali The five different plant densities, viz. T1- square system, T2 -hedge row system, T3 -double hedgerow system, T4 -paired planting and T5 -cluster planting system were taken as treatment. Among them paired planting system performed best in respect to yield (8.21kg/tree.).Thus, rejuvenation of high density planting of Amrapali mango orchard improves the growth yield and quality of plants by modifying the canopy architecture and canopy microclimate.
