Abstract:

An experiment was conducted at BCKV, Gayeshpur Farm, West Bengal to study the effect of different pruning intensities on tree vigour flowering and fruiting in guava. 7 year old guava trees were headed back at 1m, 2m and 3m height from the ground level in the month of April and May with no heading back (control) in 2012 (T1- 1m heading back in April, T2- 2m heading back in April, T3- 3m heading back in April, T4- 1m heading back in May, T5- 2m heading back in May, T6- 3m heading back in May, T7- control). Sub-treatment was given to the headed back trees (S1- No pruning (Control), S2: Pinching of 3 month shoot, S3: 50% pruning of 3 month shoot, S4: 50% pruning of 4 month shoot, S5: One leaf pair pruning of 3 month shoot). It was observed that 2m heading back in April followed by 50% pruning of 3 month shoot (T2S3) proved to be beneficial for increasing number of flowers per shoot (62.39), obtaining higher fruit set (83.33%) and higher number of fruits per shoot (54.14) ultimately increasing the yield per shoot (4.98 kg/shoot).
