- Abstract
The objective of this work was to determine the double coefficient of maize corn crop for the municipality of Tangará da Serra - MT, using weighing lysimeters. The experiment was conducted in State University of Mato Grosso - UNEMAT's campus, and the soil was classified as dystroferric Red Latosol, with very clayey texture. Sowing was carried out on May 2, 2015, in the six weighing lysimeters, previously calibrated with determination coefficients above 0.99. For the border, a no-till seeding with row spacing of 0.45 m was used. Harvest was performed manually on 08/16/2015. Irrigations were performed according to the potential evapotranspiration calculated daily by the lysimeters and irrigated when necessary by a sprinkler system composed of 6 sprinklers, with distribution uniformity coefficient of 86%. During the development of the culture, mass variation of microlysimeters was measured daily by weighing, determining the evaporation of water in the soil in all phases of the culture. During the culture cycle the average temperature was 24.5 ° C and the total water supply was 571.4 mm. The average Kcb values obtained in the initial phase, full development and maturation phases were 0.7, 1.10 and 0.3 respectively.
