This study was conducted at growing season of 2002 ـ 2003 at two locations to study the effect potassium (0 , 36 , 72 , 108) kg.ha-1 added to the soil as potassium sulfate and three levels of boron (0 , 5 , 10) ppm sprayed to the leaves of sugar beet and their interaction on the growth ,of sugar beet (Beta vulgaris L.), using randomized complete block design (R.C.B.D) with three replicates. The quantities characteristic for the sugar beet crop, which included, weight per one plant, total yield (ton.ha-1) in roots. The results show that the use of higher levels of potash fertilizer and sprayed with boron and their interactions caused a significant effect on yield quantity by increasing the total yield, yield per one plant and weight per one root. The effect of the interaction of potassium and boron at higher concentration was more significant than each factor alone. potash fertilizer treatment at a rate of (108) kg K/ha with (10) ppm boron gave an increase in each of the characterize in two locations. Higher response to fertilizer (K and/or B) application was found in the soil of Al- Sheikh Mohamed location compared with Qaber Al-Abed location, in the root yield quantity by increasing the total yield Also the fertilizer efficiency were higher in AL-Sheikh Mohamed soil compared with soil of Qaber Al- Abed at all levels of added potassium and boron fertilizers.
