Effect of CPPU, promalin and hydrogen cyanamide on flowering, yield and fruit quality of kiwifruit

A field experiment was conducted on bearing vines of kiwifruit cv. Allison to find out the effect of CPPU, promalin and hydrogen cyanamide on bud break, flowering, yield and fruit quality. The bud break and flowering was advanced by 6–7 days in vines sprayed with 4% hydrogen cyanamide. The results indicated that dipping of fruits in 10 ppm CPPU solution 14 days after full bloom gave highest fruit yield and registered 44 and 51% increase in yield over control. The highest yield of ‘A’ grade fruits was obtained with 10 ppm CPPU treatment, which also produced better size and quality fruits, and also gave maximum net return per vine as compared to other treatments.
