The aim of this study was to investigate the effects of several bud loading levels in winter pruning and nitrogen doses on yield and physical and chemical properties of fresh vine-leaves of grape cultivar “Narince”. Vines trained with bilateral cordon system was pruned to yield 35000 to 53000 buds/ha (16 or 24 buds/vine) above second bud in 2005 to 2006 growing season. Four nitrogen doses (0, 70, 140, 210 kg N /ha) were applied, in a completely randomized block with four replications. Brined-grape leaves were collected four times during growing season. Total fresh leaf yield (g/vine; kg/ha), number of leaves in 100 g samples, leaf area for physical properties; dry matter, ash, pH and titratable acidity for chemical properties were determined. Bud loading levels and N applications had significant effect (P |
