Abstract

In order to get maximum winter and minimum rainy season crop of guava, cv. Allahabad Safeda, the trees were sprayed with aqueous solutions of urea of different concentration. The first spray was done during the last week of April/first week of May followed by second spray at an interval of 15 days. With the increase in the concentration of urea, rate of defoliation/deblossoming increased. 15 per cent urea spray was found to be optimum in regulating the guava crop with no adverse effect on the yield and quality of fruit.
