Cultural manipulation for the yield and quality enhancement of Pant Prabhat guava

Abstract

An experiment was conducted on seven year old guava cv. Pant Prabhat with four different canopy heights and three different planting densities, along with their interactions to study their impact on yield and quality for winter season crop. Canopy height with 1.25 m was incomparable over other treatments with respect to fruit yield, fruit weight and chemical qualities viz. TSS, total sugars, pectin and sugar: acid ratio. Unpruned (control) trees reported earliest flower bud initiation. Among planting densities, 3333 plants ha-1 was recorded as best in terms of fruit set, fruit yield, fruit weight and quality of fruits. Of different interactions studied, plants of canopy height 1.25 m with density of 3333 plants ha-1 revealed their superiority against other combinations. It is, therefore concluded that plant population of 3333 plants ha-1 with canopy height of 1.25 m is best for higher yield of quality fruits of guava cv. Pant Prabhat.
