Two field experiments were conducted at Sakha Agricultural Research Station, Kafr-EL-Sheikh Governorate during the two successive seasons 2002 - 2003 and 2003 - 2004 to investigate the effect of soil K-fertilizer at 100 and 50 O/O of the recommended rate (24 kg K20/fed), foliar application with growth regulators (IAA and/or Kinetin) at levels of and 10'~ Molar and their combination on some physio-chemical properties and yields of sugar beet plants. The results indicate the following: 1- Decreasing K-rate from 24 to 12 kg K20/fed led to obvious reduction in root diameter and length, fresh and dry weights of root and top, leaf area and yields of roots, tops and sugar. Decreasing the K-rate also decreased the chemical properties namely: individual sugars, invertase activity and mineral elementals composition. Meantime, root impurities (K and aamino N) and some technological parameters, i.e. sugar lost in molasses (SLM), extractable sugar (Ex s) and alkalinity coefficient (AC) showed the same trend. On the contrary, decreasing the Krate only increased juice purity and Na O/O in the juice...
