Viticulture is an important agricultural branch in Turkey. Grape is the most grown fruit species in Turkey. The study was conducted with ‘Alphonse Lavallée’ 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 87.64 g/100 g with HS, 87.76 g/100 g with 1/3 CTR + HS, 87.78 with STR + HS and 87.67 with 1/3 CTR + STR + HS applications; the maximum crude protein 3.38 g/100 g with HS and 3.40 g/100 g with STR + HS applications; the maximum crude cellulose 4.46 g/100 g with HS application; the maximum total sugar content 64.64 g/100 g with STR and 64.64 g/100 g with HS applications were obtained. No statistically significant difference was found in terms of crude ash content.
