The present investigation was carried out at Horticulture Research Centre, Patharchatta and department of Horticulture, G.B. Pant university of Agriculture and Technology, Pantnagar during 2006-07 and 2007-08 to find out the suitable planting system of guava for Tarai conditions and the effect of shoot pruning on growth, yield and quality of guava cv. Sardar. The treatment consisted of two factors viz., two pruning level i.e. unpruned (control), one leaf pair pruning and five planting systems i.e. Square system, Hedgerow system, Double Hedgerow system, Paired system and Cluster system of planting. Thus, there were ten treatment combinations replicated thrice in Factorial Randomized Design with single tree as a treatment unit. Finding of the present investigation revealed that annual increase in tree height, tree spread, trunk diameter and tree volume decreased significantly with one leaf pair pruning, while tree spread, trunk diameter and tree volume increased with decrease in plant population per unit area. Annual increase in tree height was maximum in treatment combination unpruned and Double Hedgerow system of planting during both the years, while annual increase in tree spread, trunk diameter and tree volume were maximum in treatment combination unpruned and square system of planting. Flower bud emergence was significantly increased with one leaf pair pruning during winter season crop. Maximum number of flower bud emergence was found in treatment combination one leaf pair pruning and square system of planting. One leaf pair pruning significantly increased the winter season crop as compared to unpruned (control). Maximum number of fruits per tree and yield kg per tree was found in treatment combination unpruned and square system of planting in rainy season, while in treatment combination one leaf pair pruning and square system of planting in winter season during both the years. Yield q/ha was found maximum in treatment combination unpruned and Double Hedgerow system in rainy season, while it was maximum in one leaf pair pruning and Double Hedgerow system in winter season during both the years. One leaf pair pruning significantly improved the fruit weight, fruit size and volume, TSS, total titratable acidity, ascorbic acid content and sugars of fruit. Wider spacing gave higher fruit weight, size and TSS, ascorbic acid content and sugars of guava fruits than closer spacing. |
