Title: Effect of Nitrogen and Phosphorus Fertilization on the Performance Of Three Sugarbeet (Beta Vulgaris.L) Cultivars
Author: Marwa El-ngrashi Mustafa
Abstract: A field experiment was carried out for one season (2004 – 2005) in the Experimental Farm of the Faculty of Agriculture at Shambat to study the effect of nitrogen and phosphorus fertilizer on the growth and yield of three sugar beet (Beta vulgaris.L) cultivars under irrigation. The experiment was laid out in randomized complete block design with three replicates. Treatments were nitrogen (0-100-200 kg N /ha) designated as (N0, N1, N2), phosphorus (0-100 kg P2 O5/ha) designated as (P0, P1) and three sugar beet cultivars Tomba, Possada and Monza Designated as (CV1, CV2, CV3) respectively. The results showed that nitrogen applications tend to increase in leaf number, leaf area index shoot and root dry weigh but the effect was not significant. Phosphorus application also led to increase in growth attributes. Addition of nitrogen had positive effect on roots weigh /plot and root yield /ha .but the effect was not significant. Also phosphorus application on sugar beet cultivars had no significant effect on root weigh /plot and roots yield /ha but had negative effect on sugar content (pol%) . Nitrogen and phosphors fertilizer lead to positive effect on brix % fiber %, and purity % of juice and increase nitrogen, phosphorus, potassium and sodium content on roots. Nitrogen and phosphorus application tend to increase moisture content in root. Moreover, interactions between the treatments were not significant.
