Successive and profitability 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 successive and profitability of pruning in canopy management and high density planting in Guava orchard under Western Uttar Pradesh condition. The experiment was carried out in the orchard established at Research Farm, Krishi Vigyan Kendra, Hastinapur, Sardar Vallabhbhai Patel, University of Agriculture & Technology, Meerut, during the year 2017-2018 were studied. Rectangular system of planting and layout is preferred as it facilitates orchard operations. Planting was done in the month of February- March and August-September. Observation revealed that the pruning and high density with plant spacing (3.0 X 3.0 M) increased the fruit 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 of P. guajava cv. Florda seedless (47.20 cm) and scion girth of P. guajava cv. Allahabad seedless (44.7 cm), 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 X3.0 M spacing in during rainy season and in 6.0 × 3.0 M spacing during winter.
