Déficit hídrico em diferentes estádios fisiológicos da melancieira : efeitos em seu crescimento, produção e qualidade dos frutos.

Abstract

The culture of watermelon (Citrullus lanatus (Thunb)) together with the melon is one of the cultures more responsive to technological advances, and results, for the most part, analyzed the production and fruit quality. Among the factors involved in producing this cucurbit irrigation emerging as the most important, however, it must be handled well, since there stages of culture that require greater or lesser amount of available water, to obtain a maximum yield and high quality. From this perspective, the proposed objectives are grounded in this research project, in which considers remarkable relevance studies that may generate through agricultural experimentation, field-level, technical information in order to analyze the phenological behavior of watermelon crop under different levels of water in the soil and its implication in the production, which will serve as subsidies for efficient control and management of irrigation, thus providing, satisfactory conditions for economic viability watermelon farm in the Irrigated Perimeter Jaíbaras. The experimental design is a randomized block, with seven treatments and four repetitions, totaling 28 plots on an area of 2000 m2. At the end of the study we showed that the water stress caused problems in the development of watermelon crop, reducing the rate of leaf area, photosynthesis, thus increasing the number of abortion flowers. Thus, leading to a lower yield on fruit quality.
