Effect of pruning levels and growth regulator application on guava (Psidium guajava l.) cv. Lucknow – 49 for high yield and quality
Journal Title: Annals of Plant Sciences - Year 2019, Vol 8, Issue 3
Abstract
A field experiment to standardize the levels of pruning and growth regulator application in guava (Psidium guajava L.) cv. Lucknow-49 was undertaken at Horticultural College and Research Institute, Periyakulam during 2016-2017. The experiment consists of seven different levels of pruning and growth regulator application and the treatments were imposed on two years old trees. The results of the experiment revealed that, the treatment T5 (Light pruning + Paclobutrazol application) recorded the highest mean fruit weight, fruit length, fruit circumference, fruit pulp weight. Major objective of canopy management in guava cv. Lucknow -49 under high density planting system is to maximize the yield and maintaining the optimum canopy without overlapping. In a nutshell, taking into consideration of the performance of various pruning and chemical treatments particularly yield and yield components, the treatment T5 (Light pruning + Paclobutrazol application) in guava cv. Lucknow – 49 is best under high density planting system.
