Abstract

Guava is an important fruit crop grown in subtropical region of India. It belongs to family Myrtaceae. The demand for this fruit is increasing day by day due to its good nutritional value and its different processed products. It is also known as poor man’s apple. An on-farm trial was conducted in guava orchards of different farmers field in different villages of Nalanda district during 2020-2021 and 2021-2022 consecutively. The main objective of this trail is to force the tree for rest during undesirable season crop and shift that crop to desirable season with quality fruit by regulating the crop. The main theme of this is to enhance yield and quality of fruit by suppressing rainy season crop and promoting winter season crop by pruning or spray of 10 percent urea as compared to farmer’s practice. The practice of farmers is usually taking major crop in rainy season fruit with poor quality, insipid taste with poor shelf life in most part of the Bihar. For crop regulation different methods such as withholding irrigation, pruning of current season shoots in different ways, spraying of different chemicals is used according to different agro climatic regions. In our trial we have done 50 percent pruning of current season shoots in the month of April in ten trees and spray of 10 percent urea solution on ten trees at the time of blossoming at different locations. We got the best result in pruning of 50 percent current season shoot with 27.69 kg/plant yield with 11.40  Brix T.S.S during 2020-2021 and 28.06 kg/plant with 11.60 Brix T.S.S during 2021-2022.The best treatment is pruning of 50 percent current season shoots in the month of April is best for getting higher yield and getting maximum quality fruit for guava grower . Although the T.S.S. of fruits harvested in case of urea spray during winter season is at par with pruning of current season shoot.
