RODRIGUEZ-CABELLO, Jesús; PEREZ-GONZALEZ, Aymara; ORTEGA-GARCIA, Loreilys  e  ARTEAGA-BARRUETA, Mayra. Hydrosustainable study in tomato cultivation, its effect on fruit yield and quality. cultrop [online]. 2020, vol.41, n.2, e06.  Epub 19-Mar-2020. ISSN 0258-5936.

Tomato is the most consumed vegetable in the world. In Cuba, most sowings are concentrated in the months of lower rainfall, so the application of high volumes of water for irrigation is needed. The evolution of Cuban agriculture and the effects of climate change, makes it necessary to study the water needs of crops in each environment, and a new focus on their determination. The objective of this study is to evaluate different irrigation variants in tomato cultivation and its effect on fruit yield and quality. The research was carried out in organoponic, using eight treatments that ranged between 100 and 10 % of the volume of water applied daily. Descriptors related to the components of plant growth, yield and fruit quality were evaluated. The response of the plants was characterized by the induced effect due to the different levels of irrigation. In the first 40 days after planting, no differences were observed between treatments. The water needs of the plants became evident from flowering. In the treatments of greater water stress, the organoleptic quality of the fruit was superior. The results indicate the possibility of reducing the water supply to the tomato crop to 10 % until pre-flowering and 60 % in the following phases, to obtain quality fruits, without affecting the components of plant growth and yield.
