| Abstract:
Bud loading and thinning experiments were carried out on a 6-year old ‘Hayward’ orchard. The number of buds per vine, loaded on 6- and 12-nod long canes, were 100, 150, 200, 250, 300, and 350. No differences were determined between 6- and 12-not long canes for yield and yield parameters. The mean yields of vines loaded with 100 and 150 buds were 41.0 and 54.4kg respectively, while it reached to 70 kg/vine (38 t/ha) with that of vines loaded with 200 buds. Increasing the number of buds up to 350 per vine did not significantly affect the yield. No significant differences were found between the treatments for the mean fruit weight, TSS and fruit firmness at harvest, and annual vegetative growth. The thinning experiment was based on leaving 1,2,3, or 4 fruits per shoot and control. The thinning practice did not significantly affect the mean fruit weight and flesh firmness. The less thinning practice resulted in a delay of fruit maturity. Thinning to 4 fruit/shoot did not significantly affect the yield when compared with the control, being 67.0 and 70.9 kg/vine respectively. | |
