Taranenko E. Productivity of grapes bushes under influence of the root feeding by complex of the microelements (Ni, Cr, Mn, Ti) on the South of the Ukraine

This research is devoted to studying of action and afteraction of microelements com-plex in composition of Ni, Cr, Mn, Ti salts with concentration 0,03% under nonroot and root feeding of young and fruitful bushes which displays in increasing of the growing power of bushes and development of significant leaf surface, in improving potential fruit-fulness power, productivity and berries quality. The developed way foresees nonroot feed-ing with the microelement complex three times during vegetation: before 1-2 days before blossom with a size of a berry as a pea, in the beginning of ripenning by spraying; root feeding with the help of hydroborer in three periods: in the beginning of sap ascent, in the beginning of blossom and with the size of the berry as a pea (declaration patent: №15214, МПК А01G 17/02 (2006.01), А01С 17/00 (2006.01), №.13397, МПК (2006) А01G17/02 (2006), А01С 17/00 (2006). Microelements complex with joint using on young vineyards provides increasing of the productivity on Chardonnay kind as 21,9%, on Pinot black as 62,2%, on fruitful bushes in accordance with kinds it's about 36,8% and 30,6% comparing with control, and during a year afteraction on Chardonnay kind is 45,1% and Pinot black it's 47,4%, on fruitful ones it's 35,9% and 24,2% accordingly. The introducton of nonroot and root feeding with the microelements complex on area 77,8 h provided the income in amount of 141358,8 grn., or 1816,9 grn. per 1 h.
