| Popis: | In order to study the effects different concentration of humic acid and acetic acid foliar application on yield and leaves nutrient content of grape (Vitis vinifera), a field experimental in randomized complete block design with three replications was conducted in 2010. Foliar application treatments were T1: Control, T2: Acetic acid (1000 mg kg-1), T3: Humic acid (300 mg kg-1), T4: Acetic acid (1000 mg kg-1) + Humic acid (300 mg kg-1). Obtained results showed that: Spray treatments had significant effect on yield, cluster length and diameter and Iron, Potassium and Phosphor leaves content of grape. Maximum and minimum amount of fruits yield was obtained in T3 (Humic acid) and T1(Control) treatments respectively. Highest amount of length and diameter of grape cluster and leaves Iron content was recorded in T4 (Acetic acid) + Humic acid) but maximum of phosphor and potassium was recorded in T3 (Acetic acid) and minimum amount of all characters was recorded in T1 (Control). Key words: Humic acid, acetic acid, zinc, foliar application, grape, yield. |
