An experiment was conducted in Romania in 2004 to investigate the effects of 2 watering methods (drip and furrow irrigations) and 2 weeding methods (2 herbicide treatments and 1, 2 and 3 weedings) on the water consumption of tomatoes. The herbicide used was Pantera [quizalofop-P] 40 EC. The water consumption increased as the number of weedings increased. The water consumption was higher in the furrow irrigation than in the dripping irrigation. The drip irrigation recorded higher yield than the furrow irrigation. Each extra weeding resulted in significant yield increase. The water capitalization coefficients (WCC) showed that those irrigated by dripping method used 55-56 l of water to produce 1 kg of fruit while those irrigated by furrow method used 88-90 l of water for the same purpose. The weeding treatments did no influence the WCC value because when the yield increased, the water consumption also increased, and the ratio between them remained constant. The drip irrigation is recommended in tomatoes to ensure high yield with relatively low water consumption. The application of 2-3 mechanical weedings is also recommended, which although lead to higher water consumption they ensure higher yields.
