Abstract

Guava (Psidum guajava L) is one of the most promising fruit crops of India and is considered to be one of the exquisite nutritionally valuable and remunerative crops. In recent years guava is getting popularity in the international trade due to its nutritional value and processed products. Generally guava bears two crops in a year. The fruits produced in rainy season are rather insipid and watery and do not keep well. The winter crop is the one ordinarily as is not only larger size but of much better fruit quality. Main objective of crop regulation is to force the tree for rest and produce profuse blossom and fruit during any one of 2 or 3 flushes. This aims at regulating uniform and good quality fruit and maximizing produce as well as profit. Fruits like guava, pomegranate and lemon flower 2 to 3 times in a year. A good harvest is possible only if crop is regulated to single season ie Bahar otherwise the uninterrupted continuous blossoms would produce light crops over the whole year and require a high cost for the watch and ward and marketing. The selection of Bahar at a location is mainly determined by availability of water, occurrence of diseases, pests and marketing position. Crop regulation is achieved by the various techniques like withholding irrigation, flower bud thinning, shoot pruning and application of different chemicals.
