Abstract
Two field trials were conducted during 2009/2010 and 2010/2011 seasons in Nubaria Research Station. Alexandria Governorate. The major goal was to study the effect of nine treatments which represented the combination between three foliar spray of some micronutrients solution levels (1/4, 1/2 and 3/4 /300 L water/fed) at 45 and 75 days from sowing and three nitrogen fertilizer levels of (80, 100 and 120 Kg/fed). A split plot design with four replications was used. The main plots were assigned to foliar spray with some micronutrients solution, whereas, nitrogen fertilizer in the sub plots.
The obtained results revealed that: foliar spray of micronutrients solution level at 1/2 l/fed attained a highest values for root diameter and fresh weight/plant, as well as, sucrose%, purity%, root and sugar yields/fed. While, N, Na and K% were decreased in both seasons. Foliar spray of micronutrients solution level at 3/4 l/fed increased root length and macroelements (g/100 g DW) in both seasons.
Application of nitrogen fertilizer at 120 kg N/fed gave the highest mean values of root length, diameter, fresh weight/plant, root and sugar yields/fed. On the contrary, a gradual reduction in sucrose% and purity% had been detected with the increase in nitrogen level over 80 kg N/fed.
Interaction between foliar spray of some micronutrients solution levels 1/2 l/fed and nitrogen fertilizer at 120 kg/fed significantly affected on sucrose%, root and sugar yields/fed in both seasons.
