 Abstract

The objectives of this study were to evaluate the influence of winter season and nitrogen fertilizer on Bt. Cotton (Bacillus thuringiensis) performance, increasing crop land, and the possibility of to growing cotton year around. The study was conducted during November, 2014 to April, 2015, at the Demo farm, University of Bahri, College of Agriculture, at Alkadaro-Sudan. It was arranged in Randomized Complete Block Design (RCBD) with four treatments and four replications. The studied plant characters included, the leaf number, plant height, leaf area, number of branches, number of flowers, and number of bolls. The results displayed that all studied parameters showed non-significant differences at (P≥0.05). Application of 100kgN/fed increased the number of leaves (261.50), number of flowers (50.80) and the number of bolls (29.50) compared to other treatments, while the 75 kg N/fed has increased the plant height (176.70) and the leaf area (LA) (218.70). However, the 50 kgN/fed has increased the number of branches (43.0). The study concluded that Bt. cotton is a successful and profitable winter crop and recommended the replication of this study in different seasons, soils and locations.
