YIELD, QUALITY AND STABILITY EVALUATION OF THE EFFECT OF BIO FERTILIZER APPLICATION ON SUGAR BEET UNDER IRRIGATION SYSTEMS IN NEWLY RECLAIMED SANDY SOILS

Abstract

Field experiment was carried out at the experimental farm of the Agricultural Research Station, National Research Centre El-Nubaria district, Egypt during the winter season of 2016/2017 to evaluate the effect of foliar application of humic acid and yeast as bio fertilizer on yield and quality of sugar beet under two method of water irrigation ( Surface and subsurface).Results showed that subsurface irrigation was more efficient than surface irrigation. The results also indicate that dual application of humic acid and yeast have promoting effect than single one and such effect was more pronounced under subsurface irrigation.
