Abstract

The objective of this work was to evaluate the effect of PW on productivity and water relation on watermelon culture (Citrullus lanatus). The experiment was carried out in the experimental field of UFAL, Campus Arapiraca - UFAL. The missiles were completed in a randomized design, consisting of drippers with two flows (1.39 L h-1 and 1.92 L h-1), being twice and twice, totaling four treatments (PW - 13, 14, 25, 19 and 22 %), with six replicates. Tensiometers were read out to monitor soil water potential and the infrared thermometer to monitor the temperature on the sheet. Also, phytotechnical indexes were evaluated (Tukey's test, 5%). Based on the analysis of the results, a statistical comparison was not observed for the verified attributes, which were: fresh mass, soluble solids content, fruit diameter and length. As the temperature curves for both treatments are similar for all treatments. T1 absorbed more water in depth. It concludes that PW values ​​below the recommended do not affect crop productivity and that the percentage of water is influenced as depths of water absorption by the crop.
