Abstract
Two field trials were conducted during 2012/2013 and 2013/2014 seasons at El-Manyal Village, Talkha District, Dakahlia Governorate, to study the effect of plant distribution sowing patterns and nitrogen fertilizer levels on yield and quality of sugar beet, "cv. Kawemira". The obtained results indicate that:
1- Sowing distribution patterns had significant effects on all studied characters over the two seasons, except for root diameter in the second season The studied sowing patterns(28, 24 and 20 or 35, 30 and 25 cm between hills in the two sides of terrace (mastaba) led to significant differences on the most of the studied characteristics in both seasons. Sowing beet seeds in both sides of terrace 80 cm width at 25 cm distance between hills led to significant increase in yields of roots, gross sugar and white sugar (t/fad) as well as the percentage of the extractable white sugar.
2- Increasing nitrogen fertilizer levels from 80 to 100 and 120 kg N/fad, significantly increased root fresh weight (g), root diameter, sugar loss percentage, the yields of root, gross sugar, white sugar and lost sugar/fad in both seasons besides root length (cm) in the second season. On the other side, it significantly decreased root gross sugar and extractable white sugar percentages in both seasons.
Generally, it could be concluded that sowing sugar beet seeds at 25 cm apart between hills on the two sides of terrace (mastaba) 80 cm width and adding 120 kg N/fad is recommended to maximize its productivity and quality under the environmental conditions of Dakahlia Governorate.
