Abstract

This study was carried out in the year 2003 to investigate the effects of different water regimes (40, 60, 80, 100 and 120% of water requirement) and different amounts of NITROGEN (60, 120 and 180 kg ha-1) as well as their interaction on quantity and quality of TOMATO ‘Early Urbana’. The experiment was performed in Research Farm of Faculty of Agriculture, Tehran University (a semi-arid area) on a clay loam soil, using a split plot design with three replications (irrigation treatments as the main plots and different amounts of NITROGEN as sub-plots). Results indicated that different treatments of irrigation and NITROGEN as well as their interaction have significant effects on TOMATO quantitative and qualitative characteristics including total YIELD, marketable YIELD, number of fruits per plant, average fruit weight, WATER USE EFFICIENCY (WUE), early ripening, dry matter, total soluble solids, terrible acidity, pH, vitamin C, firmness and N-NO3. The maximum marketable YIELD and WUE were obtained at 100% water requirement with 120 kg ha-1 NITROGEN (78.83 t ha-1 and 0.085 t ha-1 mm-1, respectively). In this study, third order and second order functions were obtained between applied water and marketable YIELD, and NITROGEN and marketable YIELD, respectively. Also a multiple regression was found between marketable YIELD and water and NITROGEN consumption.
