Abstract
Two field experiments were conducted during two successive seasons 2012/2013 and 2013/2014 at Nubaria area, Alexandria Governorate, in order to study the effect of foliar application of B, Fe, Zn and Mn at the concentrations of 1.0, 1.5 and 2.0 L /400 L water/fed and potassium fertilizer levels (24, 36 and 48 kg K2O/fed.) on yield and physiological characters of sugar beet plant (Beta vulgaris L.) under newly reclaimed soils.
A split plot design with four replications was used. Results revealed that foliar application of B, Fe, Zn and Mn at the concentration of 1.5 l/fed recorded highest root diameter and root fresh weight/plant, as well as, sucrose%, root and sugar yields/fed., while, foliar application of B, Fe, Zn and Mn at the concentration of at 2 l/fed gave tallest root and percentage of root impurities (a- amino-N, Na and K). Fertilization of potassium at rate of 48 kg K2O/fed gave highest values of root length, root diameter, the percentage of a-N, Na, K as well as root and sugar yields/fed in both seasons. On the contrary, a gradual reduction in sucrose% had been detected with the increase in potassium level over 36 kg K2O/fed, while application of potassium at rate of 24 kg K2O/fed recorded the lowest values in all characters in both seasons. The interaction between foliar spraying of B, Fe, Zn and Mn at the concentration of 1.5 l/fed and potassium fertilizer at rate of 48 kg K2O /fed significantly affected root and sugar yields/fed and sucrose% in both seasons.
It could be summarized that, application of potassium at rate of 48 kg K2O /fed and foliar spraying of B, Fe, Zn and Mn at the concentration of 1.5 l/fed significantly k,affected root diameter and root fresh weight, root and sugar yields/fed. as well as sucrose%
