Effect of Mineral and Bio-Fertilization on Yield, Yield Components and Quality Traits of Sugar Beet Plants

Abstract

Two field experiments were carried out at the Agricultural Research Farm of Delta Sugar Company at El-Hamol, Kafr El-Sheikh Governorate during two winter seasons of 2008/2009 and 2009/2010 to study the effect of mineral and bio-fertilization on yield and its components and quality of sugar beet plants. A split plot in stripe design with four replications was used, where nitrogen fertilizer treatments were occupied in the main plots and the bio-fertilizer (soil or spray) treatments were distributed in the sub-units (in the horizontal strips). The results could be summarized as follows: -Increasing nitrogen fertilizer significantly increased the yield and its components traits, while the quality traits were decreased. -The highest values for yield and its components traits were found either with yeast treatment or by using the mixture of macro & micro spray treatment with amino acid treatment in the first or in the second season. -The highest values of sugar beet quality traits were recorded by humic acid or by the effective microorganism treatment. -Generally, the significant highest values of yield and its components traits either by using yeast treatment or by using the mixture of macro & micro treatment with amino acid treatment together with 120 kg N/fed. While the quality traits had the highest values by using the mixture of macro & micro treatment with amino acid treatment or by using the yeast treatment under 80 kg N/fed. treatment.
