In order to evaluate the effects of zinc and phosphate fertilizers on sugar beet yield and agronomical characteristics, an experiment was carried out as factorial based on RCBD with four replications in farm of Navaze village, Arak, Iran in 2010. Experimental factors were including of two levels of zinc utilization (Based on soil test 25 kg/ha) and non zinc utilization and also four level of phosphate fertilizer based on soil test, ammonium super phosphate 125 kg/ha, 250 kg/ha, 375 kg/ha and non P application as control. The indexes assessment were including of number of green leaves, number of yellow leaves, number of dry leaves, Percent of leaf water content, leaf area index, root water content, root length, Percent of purity sugar and sugar yield. Result showed the most purity sugar was 625 g/m2 by apply of 375 kg/ha ammonium super phosphate plus zinc application.
