Systems of crop regulation in guava and their assessment

Abstract

The guava (Psidium guajava L.) is a fruit that has the potential to be profitable as well as being nutrient-rich. It has two seasons of blooming. However, in terms of production and quality, both season crops differ. The basic principle of crop regulation is based on the fact that guava flowers appear on new tender, vigorous on developing vegetative growth and the plant is compelled to be dormant and after the resumption, it (tree) produces bumper flowers and results in a heavy yield of better quality. Above all, such a cropping pattern results in increased grower returns while keeping control over consistent, high-quality fruit production. On the contrary, continuous blooming would result in lower yield along with extra watch and ward and marketing costs. Henceforth various techniques are used to regulate guava crops including withholding irrigation, flower bud thinning or removal, pruning level technique. All these techniques help to lower fruit set during the rainy season along with incline production in winter season. This paper includes all previous efforts concerning regulations/recommendations to date and future perspectives.
