INTRODUCTION
Sugar beet (Beta vulgars, L.) is the second main source of sugar after sugar cane not only in the world but also in Egypt. The present situation in Egypt is that total white sugar production was 1.65 million tons in 2007, this represents about 72% of the total consumption and the gap (28%, 644000 tons) is covered by important, about 30% (449418 tons) was produced from sugar beet and the rest, 70% (1.048327 million tons) is produced from sugar cane, in addition to 152000 tons from liquid sugar (Allam, 2005).Sugar beet is a biannual plant is very important in agricultural because of not only its ability to store sucrose to high concentration in its storage root, but also to its by products which are used for alcohol production and live stoke feeding Also sugar beet has a wide adaptability to grow in poor, saline, alkaline, new reclaimed calcareous soils. Besides, sugar beet makes the soil in good condition for the benefit of the following crops especially by enhancing the aeration of the soil.
For the fuore mentioned advantage in addition to its limited water requirements (3500 m3/fad/6 mouth) compared to sugar cane (12140 m3/fad/year) (Allam, 2005). Sugar beet has recently received wide attention from the government of Egypt that make all effects to expand sugar beet cultivation in the newly reclaimed land where some element especially P,K and micronutrients are in short supply for normal growth and high yield of root and sugar.
Nutrition is essential for plant life and yield, therefore, mineral fertilization is a common agronomic practice that leads to improve productivity. Mineral fertilization includes several elements however; phosphorus and potassium are among the macro elements that used in fertilization. Micronutrients are contained in or essential for activating some of the enzyme involved in photosynthesis and respiration systems, moreover some of them are essential for the formation of new leaves in meristems and have a vital role in sugar translocation not only from leaves to roots but also inside the root itself during sugar accumulation.
There fore, the objective of this study was to find out the effect of potassium, phosphors and micro nutrient fertilization on vegetative growth top and root yields as well as quality parameters of sugar beet plants.
