Subject(s): Online resources: In: Zagazig Journal of Agricultural Research 2005.v.32(1)Summary: Two field experiments were carried out during two winter seasons ofl997-1998 and 1998-1999 to study the effects ofMg and K as foliar and soil applications as wen as their combinations on yield, its components and quality of sugar beet under south Dakahlia soils conditions. Sugar beet yield components i.e. root length, root diameter as wen as root weight and top weight per plant were increased by Mg foliar application with the two ntes of 0.5 and 1.0 kg Mglfed., The effects were significant only on root diameter at nte of 1.0 kg Mglfed. Magnesium soil application with the two ntes of 7.5 and 15 kg MglfecL caused significant increases in the aforementioned components. Also, root and top yields (ton/fed.) of sugar beet were significantly increased by the two ntes ofMg soil application while, these yields were not affected by the two ntes of Mg foliar application. Potassium foliar application with the nte of 5 kg K20/fed. caused a significant increase in root weight/plant only. Raising rate of K foliar application to 10 kg K20/fed., root length and root diameter were significantly incrCBsed. Root yield/fed. was slightly inCrCBSed by foliar application of 10 kg K20/fed. While, top yield was significantly decreased by the two ntes ofK foliar application. Root diameter was significantly incrCBsed by soil application of 48 kg K20/fed. Root yield/fed. was slightly increased by both ntes ofK soil application (24 and 48 kg K20Ifed.). T.S.S. % in the second season, sucrose % in both seasons and combined as well as juice purity % in the combined were significantly increased by foliar application of 1.0 kg Mg / fed. but the rate of 0.5 kg Mglfed. showed no effect. Soil application of both 7.5 and 15 kg Mg Ifed. caused a significant increase in T. S. S. % in the second season. Meanwhile, soil application with 7.5 kg Mg/fed. gave significant increase in sucrose % in both growing seasons and their combined. T.S.S. % positively and significantly responsed to K foliar application up to 10 kg KzOlfed. while, juice purity % responsed up to 5 kg K2O/fed. only. The combined analysis revealed that both T.S.S.% and juice purity %were not affected by soil application ofK whereas, sucrose % was increased by adding of 24 kg K2O/fed. Sugar beet root and top yields (ton/fed.) as well as quality parameters of sugar beet were significantly influenced by the interaction between Mg and K applications.
