The investigation was carried out in Yabú Protected Crop Houses Business Unit, in Villa Clara; Its main objective was the evaluation of the irrigation technology in cultivation houses in the production of pepper and tomato. Analyzes of water and soil quality were carried out using laboratory techniques, calculation of irrigation uniformity using pluviometric techniques, and the evaluation of two geometric designs of emitters based on the yield components in different hybrids of tomato and pepper. The quality of the water showed that it presents unfavorable values in the chemical parameters: Residual Sodium Carbonate, Percentage of Possible Sodium and pH, demonstrating that there is chemical contamination in the water by salts. The soil analysis showed that the Structure Factor and Permeability presented insufficient values; the irrigation uniformity showed that there are deficiencies in the uniform application of irrigation since more than 50% of the experiments presented unfavorable values; and that the triangle design presents greater benefits compared to the frame when we assess the performance components. The results aim to find alternatives to optimize the improvement and quality of irrigation water, soil and application of irrigation standards.
