IMPROVING PRODUCTIVITY OF BANATY GRAPEVINES BY FOLIAR APPLICATION OF BORON, MAGNESIUM AND ZINC
This investigation was carried out during 2015 and 2016 seasons on cane trained Thompson seedless grapevines grown in a private vineyard located at El-Shuhadaa district, Menoufia Governorate. The vineyard soil texture is clay loam . The selected vines are planted at 2 × 3 meters apart. Pruning was conduced on the first week of Jan. in both seasons leaving 64 eyes per vine (4 fruiting canes × 14 eyes plus four replacement spurs × two eyes) .This study was initiated for elucidating the effect of single or combined application of boric acid, magnesium sulphate and chelated –Zn on the main shoot length , leaf area , berry setting percentage , yield and as well as physical and chemical properties of Thompson Seedless grapes. Selecting the best treatment that responsible for producing filled clusters and higher productivity quantitively and qualitatively is considered another target . Results showed that spraying boric acid at 0.05%, chelated –Zn at 0.05% and magnesium sulphate at 0.5% ascending order was very effective in enhancing the leaf area , berry setting , yield and quality of the berries . The best results were obtained with using the three nutrients together . For producing filled clusters and improving yield quantitively and qualitatively of Thompson seedless grapevines , it is necessary to spray vines with boric acid at 0.05%, chelated –Zn at 0.05% and magnesium sulphate at 0.5% four times at the growth start, first bloom , just after berry setting and at one month later .
