| Abstract | ||
| To evaluate the effect of fertigation, an yield quality of tomato a field study was conducted in Berjesia experiment station at winter season 2006-2007 in sandy loam textured soil classified as Typic quartiz pasament . Split-Split Block of RCBD Design was used to study fruit quality response to soil moisture 0.1 and 0.2 bar (main plots). Methods of N application (fertigation, broadcasting and ½ fertigation + ½broadcasting) as sub plots and Nitrogen levels 100, 200, 300 kg N ha-¹ as sub-sub plots. Results indicated the significant effect of adding N levels using different application methods on tomato fruit quality. Fertigation significantly exceeded other methods at water content 0.1 bar. Adding N up to 300 kg Nha-¹ improved of tomato quality components. Also using fertigation increased percentage of total solids 5.45% acidity 0.55 % and vitamin C 20.30 mg100 ml of tomato juice. The level 200kg N ha-¹consedered the optimum level for tomato growing drip irrigation in desert soils to avoid loss of N fertilizers by leaching on the basis of the results obtained in this study. Applying 200 kg N ha-¹ in drip irrigation with soil moisture of 0.1 bars are recommended for tomato production in desert soil in Basrah. | ||
