Abstract
This study was conducted at El-Ghorieb Exp. Farm, Assiut University, Assiut,Egypt, during 2010/2011 and 2011/2012 seasons to investigate the effect ofpotassium fertilization (48 and 72 kg K2O fed.-1) and the foliar spray with threezinc chelate levels zero, 75, and 150 mg l-1 as Zn-EDTA (15% Zn) on yield andquality as well as Fe, Mn and Zn contents of sugar beet plants grown on a calcareoussandy soil.- All plant characteristics and quality traits of sugar beet i.e., top and rootfresh and dry weights, sucrose content, sugar recovery, recoverable sugar yield,as well as Fe, Mn and Zn contents were significantly increased by increasing theK level from 48 to 72 kg K2O fed.-1 in both seasons.- Increasing the potassium level caused an increase in the sucrose percentage.Moreover, a remarkable increase in the recoverable sugar percentage wasobserved as K level increased. Potassium fertilization showed a significantly increaseon sugar beet yields at 48 kg N fed.-1 level as well as 72 kg K2O fed.-1 fortop yield and recoverable sugar yield.- With regard to zinc foliar application, significant decreases on impuritiesand increases on sugar loss to molasses and sucrose percentage were observed. Italso had an insignificant effect on the recoverable sugar percentage. In mostcases, increasing Zn level up to 150 mg l-1 significantly increased the sugar beetyields fed.-1- Potassium fertilization x zinc foliar application interaction had a significanteffect on Na content in beet roots in both seasons. Moreover, significant effectswere observed only on K content in beet roots and sugar losses to molassesin the first season as well as top yield fed.-1 in the second season. It could be concludedthat application of the K fertilization at 72 kg K2O fed.-1 along with thefoliar application of zinc had a positive effect in increasing all growth traits ofsugar beet
