Abstract

The vine leaf is an important dietary product for human nutrition by virtue of its high nutritious value and low calorie. This study was conducted in the Province of Konya in a vineyard belonging to a producer in the 2010 vegetation period. This study investigated the effects of repetitive applications of herbagreen (HG), humic acid (HA), combined foliar fertilizer (CFF) and HG+CFF performed in the MüÅŸküle grape variety grafted on 5 BB rootstock on fresh or pickled leaf size and leaf raw cellulose content. HA application increased leaf area and leaf water content values whereas HG+CFF application increased leaf raw cellulose values. The effects of the application on leaf weight and leaf volume were found to be insignificant. It was observed that leaf blade samples were efficient in terms of N, P, Fe, Mn and Cu content, but deficient in K, Ca, Mg and Zn content.

Key words: MüÅŸküle grape leaves, herbagreen, humic acid, combined leaf fertilizer, herbagreen + combined leaf fertilizer, yield, crude fiber content, nutrient values.
