Response of pruning in canopy management and high density planting in guava orchard under western Uttar Pradesh condition

Abstract

The current study was conducted to examine the response of pruning in canopy management and high density planting in Guava orchard under Western Uttar Pradesh condition. Observation revealed that with the pruning and high density with plant spacing (from 3.0 × 3.0 m) increased in yield significantly, similarly, with increase in spacing wise pruning in canopy management and high density was need to increased. Plant growth in term of stock girth (47.20 cm) of P. guajava cv. Florda seedless and scion girth (44.7 cm) of P. guajava cv. Allahabad seedless, tree spread (N-S) and canopy volume increased with the plant spacing (3.0 × 3.0 m), while tree height decreased. To increase in plant spacing, number of fruits per plant, yield per plant and fruit density was higher at 3.0 × 3.0 m and least in 6.0 × 6.0 m plant spacing. Pruning in canopy management and high planting density was found to be better owing to maximum absorption of solar radiation and optimum microclimate in the orchard leading to better yield in plants, higher fruit density and yield efficiency, However yield per hectare was maximum 3.0 × 3.0 m spacing in during rainy season and in 6.0 × 3.0 m spacing during winter.
