Hydrosustainable study in tomato cultivation, its effect on fruit yield and quality
Main Article Content
Abstract
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.
