RESPONSE OF FLAME SEEDLESS GRAPEVINES TO FOLIAR APPLICATION OF NANO FERTILIZERS

Abstract

This study was conducted through 2015 and 2016 seasons on Flame Seedless grapevines grown in a private vineyard located at El- Tawfekya village – Samalout district, Minia Governorate to investigate the effects of Six Nano fertilizers (Amino-minerals; Orgland Active- Fe, Boron-10, Amino-Zn and Super –Fe each at 0.1 to 0.2 %) on vegetative growth, vine yield, berry coloration and fruit quality. Treated vines with 0.1 or 0.2% concentration of nano- fertilizers were very effective in enhancing growth aspects, vine nutritional status and berry setting, yield, colouration and quality compared to the control treatment. The promotion was related to the application of Amino minerals, Orgland, active –Fe, Boron-10, Amino –Zn, and Super –Fe, in descending order. Conclusively, treating flame seedless grapevines three times with amino minerals nano fertilizer at 0.1% is the best treatment yield, improved berries colouration and gave high fruit quality.
