Effect of different organic manure applications on grapevine nutrient values

This study was conducted to elucidate the effects of pruning residue of grapevine, farmyard manure, green manure plant (barley + vetch), straw mulch and combinations of these materials on nutrient uptake of grapevine (V vinifera L. Cilores). Leaf samples were taken during full bloom and verasion periods and analyzed for concentrations (%) of macro elements N, P, K, Ca, Mg and micro elements (ppm) Fe, Zn, Cu, Mn per leaf. Results suggested that the applications led to significant increases in uptake of both macro (N, P, K, Ca and Mg) and micro elements (Fe, Zn. Cu and Mn) by grapevine leaves. The research showed that these environment-friendly organic material applications help increasing nutrient level of grapevine.
