The Effects of Some Summer Pruning and Humic Substance Applications on The Nutritional Value of 'Alphonse Lavallee' Grape Cultivar

Viticulture is an important agricultural branch in Turkey. Grape is the most grown fruit species in Turkey. The study was conducted with 'Alphonse Lavallee' grape variety (Vitis vinifera L.) grown on grafted 1103 Paulsen rootstock in Turkey in 2016. In the study effects of Control (C), 1/3 Cluster Tip Reduction (1/3 CTR), Shoot Tip Reduction (STR), Humic Substance Application (HS), 1/3 CTR+ STR, 1/3 CTR+ HS, STR+ HS, 1/3 CTR+ STR+ HS applications on nutritive values were investigated. According to results; the maximum dry matter content 87.64g/100g with HS, 87.76g/100g with 1/3 CTR+ HS, 87.78 with STR+ HS and 87.67 with 1/3 CTR+ STR+ HS applications; the maximum crude protein 3.38g/100g with HS and 3.40g/100g with STR+ HS applications; the maximum crude cellulose 4.46g/100g with HS application; the maximum total sugar content 64.64g/100g with STR and 64.64g/100g with HS applications were obtained. No statistically significant difference was found in terms of crude ash content.
