Abstract
A field experiment was conducted on bearing vines of kiwifruit cv. Abbott to find the effect of CPPU (N-(2- chloro-4-pyridyl)-N-phenylurea) and summer pruning on fruit yield, fruit size and quality. CPPU greatly stimulated fruit growth indicating that it can be a powerful tool for improving kiwifruit cropping. Application of CPPU at 10 ppm concentration was done by dipping the fruits for 10 sec in the aqueous solution of compound at petal fall and 30 days after petal fall. CPPU applied fruits increased size by 20-70 g over control. Summer pruning along with CPPU application proved to be more effective in obtaining fruits of high grades with increased fruit weight (95.37 g fruit(-1)) and high quality. Summer pruning, when done by pinching 1/5th at Petal Fall stage + CPPU dipping (10 ml(-1)) and pinching 1/5th continued till harvest, at one month interval resulted in increased fruit yield (54.80 kg vine(-1)), high TSS (17.60 Brix), high total sugar (9.85%), advanced ripening by one week and reduced flesh firmness.
