EFFECT OF BIO FERTILIZER, ORGANIC MANURE SOURCES AND APPLICATION METHOD ON GROWTH, LEAF MINERAL CONTENT, YIELD AND FRUIT QUALITY OF FLAMESEEDLEES GRAPES

Abstract

This investigation was conducted for two successive seasons (2016- 2017) in a private vineyard located at El-Sadat, Menoufia governorate; on Flame seedless grapevines to study the effect of organic fertilizers, application method and bio fertilizers for Flame seedless grapevines by using different sources of organic fertilizers. The chosen vines were seven years old, grown in a sandy loam soil, spaced at 2 X 3 meters apart, irrigated by the drip system, and spur-pruned and trellised by Y Shape system. Organic fertilizers (compost, city west compost and chicken manure) were applied either in the form of individual by (trench or superficial) application method. Bio fertilizers (Nitrobien and Rhizobacterien) were applied either in the form of individual as a twelve treatments. This study indicated that application of poultry manure with trench application + Rhizobacterien was the best management system for achieving the best vegetative growth parameters, leaf mineral content and ensuring the best yield with fruit quality at tributes of Flame Seedless grapevines.
