Abstract

The present study was conducted on clay soil at Sakha Agricultural Research Station, AgriculturalResearchCenter during 2003/2004 and 2004/2005 seasons. The aim of this investigation was to find out the optimum plant population density and the suitable time of sowing for sugar beet. A spilt-plot experimental design was used with in three replication. The main results could be summarized as follows : The results indicated that early sowing in October 10 produced the highest significant root yield, top yield, sugar yield/fad, root size, sucrose content and total soluble solids as compared with late sowing in November 25, in both seasons. Although, the yields of roots and sugar per faddan were not affected when plant population ranged from 26250 to 52500 plants per faddan, however, it decreased significantly when the plant population was recorded to 26250 and 29400 plants per faddan over the two seasons. Increasing hills spacing from 16, 20, 24, 28 to 32 cm significantly increased root diameter TSS% and significantly decreased top yield per fad. and purity percentage in both seasons. The combined results clearly showed that sowing at 16 or 20 cm hills pacing recorded highest root and sugar yield per fad.
