ABSTRACT

The experiment was conducted to study the interaction effect of pruning and organic manure on rainy and winter season crop of guava. The experiment was laid out using two factor interactions consisting of unpruned and one leaf pair pruning with 0, 5, 10, 15 kg organic manure and recommended dose of NPK (N 75g, P 65g, K 50g)/tree/year combination. Selected trees were uniformly pruned (retaining one-leaf-pair at the base of the current season’s growth) during the first week of May, 2008. The results showed significant variation in annual increase in spread, annual increase in trunk girth, number of new shoots emerged per branch, number of flower buds emerged per branch, number of fruit set per branch, number of fruit retention per branch, per cent fruit retention, per cent flower/fruit drop, number of fruits per tree and yield among the different treatments. Total yield per tree was recorded maximum with unpruned plants with 15 kg organic manure/tree/year.
