Abstract:

An On Farm Trial (OFT) was conducted to study the effect of different plant growth regulators viz., forchlorfenuron (CPPU) and biozyme on the development of Kiwifruit cv. Hayward in the commercial orchard of Chamba District of Himachal Pradesh during the years 2013-14 and 2014-15. The experiment was conducted at place having an approximate altitude of 1200 m above mean sea level. Six treatments using PGR’s were applied as dip and foliar application at petal fall and 15 days after petal fall stage. The different treatments viz., T1: Untreated control; T2: CPPU @ 5ppm (Dip Application) at petal fall; T3: CPPU @ 5ppm (Foliar Application) at petal fall; T4: CPPU @ 5ppm (Dip Application), 15 days after petal fall; T5: CPPU @ 5ppm (Foliar Application), 15 days after petal fall and T6: Biozyme @ 2ml/litre at petal fall, were applied. The data on fruit size, fruit weight, fruit firmness and yield along with quality attributes were recorded at harvest. The application of CPPU @ 5 ppm at petal fall as dipping application obtained a significantly higher average fruit yield of 54.20 kg per vine. Similarly, maximum average fruit size (77.75 mm length and 53.74 mm diameter) and fruit weight (121.99 g) was recorded with dip application of CPPU@ 5 ppm at petal fall. However, average minimum fruit weight (47.52 g) in untreated control. The fruits treated with CPPU obtained highest TSS (17.25 oB) and lowest fruit firmness (10.06kg/cm2). The probable reason for the higher fruit weight and yield may be the exogenous application of CPPU which being synthetic cytokinin has a role in faster cell division and cell elongation. The synthetic cytokinin, CPPU (N-(2-chloro-4-pyridyl)-N-phenylurea) has been reported by various worker all over the globe to increase fruit size, fruit weight and yield significantly (Biasi et al., 1991; Lawes et al., 1992).
