Abstract
A field experiment was conducted at AL Berjesia experiment station, Basarah province, south of Iraq during winter season of 2006-2007. The soil of the experiment was sandy loam and classified as typic quartiz psamment. Split- split plot arrangements in RCBD design was used. The objective of this study was to evaluate the response of tomato crop to three factors i.e soil water content under various tensions (0.1 and 0.2bar), nitrogen levels (0,100, 200 and 300 kg N ha-¹. and of N application methods (complete fertigation, 1/2 fertigation and 1/2 broadcasting and Complete broadcasting). So to recommend a new and effective method of tomatos var (Hutoof). Nitrogen application methods were significantly increased the total yield of tomato fruits. Fertigation on complete with 0.1 bar significantly increased this character compared with 0.2 bar. The highest yield of 32.78 ton ha-1 was obtained under 300 kg N ha-1 with no significant differences with 200 kg N ha-1 which gave 30.44 ton ha-1. This highest yield was attributed to the highest values of yield compenents i.e 16.69 fruits plant, 68.2g fruit weight and 5.59 cm fruit diameter. Tomato yield at 300 kg N ha-1 increased only 2.25% more than 200 kg N ha-1 and their was no significant differences in all studied yield compenents.
