Resumo:The determination of the correct irrigation depth for the production of tomato fruits is crucial for obtaining higher yields and higher quality fruit. The aim of this work was to evaluate the productivity and development of the hybrid fresh tomato Natália under different drip depth irrigation and two forms of manuring. The experiment was conducted in the experimental area of the Federal University of Goiás - Campus Jataí, during the months from April to September. The experimental design was randomized blocks with 4x2 factorial arrangement and four replications. Were used 4 different irrigation depth (66%, 100%, 133%, 166% of reference evapotranspiration ETo) daily of local, calculated daily by the Penman - Monteith method through the program SMAI, with data obtained from automatic weather station Jataí –GO by INMET site. The other factor studied was the manuring that was held by fertigation and conventional manuring. The fertilization was calculated according to the chemical analysis of the soil. Fertilizer application and the subdivision of the remaining fertilizer were taken in six times, with the same dosage in all treatments. Each experimental unit consisted of 3 rows with 12 plants each, being assessed only 8 plants centerline, excluding borders. The results showed that plant height and commercial productivity of irrigation depth 2 (100%) showed better performance. For the Brix value, it was found that the lower irrigation depths have favored increasing the Brix. Regarding the type of fertilizer, it was observed that fertigation requires an optimal amount of water for their efficiency. In this work the fertigation showed superior advantage than conventional manuring when combined with irrigation depth 2 (100%).
