RESPONSE OF TOMATO VARIETIES TO WATER STRESS
Background and objectives: Water scarcity is limiting for tomato (Solanum lycopersicum L) production, because they are sensitive to water stress in the different phases of development, so irrigation should be done in an optimal way; because of this, the objective was to evaluate four varieties of tomatoes in four levels of irrigation in greenhouse plants. Methods: A completely randomized experimental design with factorial arrangement was used and various agronomic variables, fruit quality and biomass were measured as response variables. Key results: Tomatoes were significantly affected (P ? 0.05) by variety (V), irrigation (R) factors and their interaction. 100% of P variety presented fruits of greater weight (122 g); while, reducing water up to 25%, weight was reduced to 84, 90, 34 and 18 g in cid, P, E and C, varieties respectively. However, in terms of yield and leaf area, 100% of the Cid variety presented the highest values, around 3.3 kg / plant and 8.6 m-2. Conclusions: Variety c was tolerant to water stress and also does not present blossom end rot (calcium deficiency) in the fruit.
