TAILIEUCHUNG - Effect of shoot pruning on growth and yield of guava (Psidium guajava L.) cv. L-49 under foothills of Arunachal pradesh

The effects of pruning months (mid-April, mid-May and mid-June) and pruning severity (pruning of 25%, 50% and 75% of shoot length from tip) on growth and yield of guava cv. L- 49 planted at a spacing of 6 m x 6 m at Fruit Research Farm, Department of Fruit Science, College of Horticulture, Pasighat, Arunachal Pradesh during April 2017 to December 2017, with an aim to optimize the time of pruning and intensity of pruning for harvesting of winter guava crop. Among different months of shoot pruning, pruning in mid-April (M1) was found to be the best for promoting plant growth parameters like plant height, collar girth, E-W and N-S canopy spread, length of shoot, fruit set and number of fruits/plant, whereas the maximum fruit yield (kg/tree) was recorded highest in mid-May pruning. The intensity of pruning in respect of length of shoot pruning also had different responses. On the basis of overall performance the study clearly revealed that pruning of 25% of the shoot length in mid-April (P1M1) was found to be the best treatment among all plant growth parameters, whereas pruning of 50% of the shoot length in mid-May recorded best for obtaining maximum fruit yield in guava cv. L-49 for winter crop in sub-tropical climatic conditions under the foot hills of Arunachal Pradesh. | Effect of shoot pruning on growth and yield of guava (Psidium guajava L.) cv.
