Effect of pruning intensities on growth and quality parameters of guava CV. Sardar under different planting densities

Abstract

An experiment was carried out during kharif and rabi seasons of 2014 -15 at College of Horticulture, Udyangiri, Bagalkot to study the effect of pruning intensities on growth and yield parameters of guava cv. Sardar under different planting densities. The data revealed that the maximum trunk girth (31.18cm), number of primary branches (3.68), girth of the secondary branches (27.49 mm), E-W canopy spread (2.68 m) and N-S canopy spread (2.63 m) was recorded in wider spacing M6. Similarly, TSS (10.45m oB)and vitamin C (94.68 mg/100g) but maximum acidity (0.3%) was recorded from closer spacing in M1.In pruning intensities the maximum girth of the plant (28.04 cm) and secondary branches (24.30mm) was recorded on very light pruned shoots in S3 but E-W and N-S canopy spread was maximum (2.43m and 2.64m) in unprunned shoots in S4 and in quality parameters the maximum TSS (10.27oB)and (11.24oB)was recorded in S3 during rainy and winter season respectively, similar observations was recorded in acidity also in both the season. The maximu Vit.C in peel and pulp was observed in S1 in both the season. While pruning intensities and its interaction with spacing did not vary significantly with respect to quality parametres.
