Effect of Tipping and Foliar Application of Proline and Botminn Plus on Yield and Quality of Grapevine (Vitis vinifera L.) cv. Khoshnaw

This study was carried out on 20 years old grapevine ( Vitis vinifera L.) cv. Khoshnaw, which was growing in Chwarta town northeastern Sulaymaniyah, Kurdistan Region/Iraq, during the growing season 2021, to investigate the effect of tipping, foliar application of proline (0, 100, and 200 mg.L -1 ),...

Description
Summary:This study was carried out on 20 years old grapevine ( Vitis vinifera L.) cv. Khoshnaw, which was growing in Chwarta town northeastern Sulaymaniyah, Kurdistan Region/Iraq, during the growing season 2021, to investigate the effect of tipping, foliar application of proline (0, 100, and 200 mg.L -1 ), botminn plus (0, 3 and 6 ml.L -1 ) and their interaction on yield and chemical characteristics of the grape. The vineyard was rain-fed cultivation and its elevation is 974 m above sea level. The results showed that tipping, foliar application of proline especially at 200 mg.L -1 , and botminn plus especially at 6 ml.L -1 gave the highest cluster weight, the number of clusters.vine -1 , total yield, TSS, total sugar, vitamin C, and Anthocyanin, While both of them did not significantly affect the percentage of phenols. The triple interaction between tipping, proline, and botminn plus significantly enhanced all detected traits since tipped vine + 200 mg.L -1 proline + 6 ml.L -1 botminn plus significantly outshine in yield and chemical characteristics of grape except total sugar and phenols compared to the untreated trees (control).
