- Abstract
The aim this research was to mensure the water requirement and the crop coefficient of the industrial tomato, BRS Sena hybrid, irrigated by subsurface drip irrigation, in the Cerrado area of Goiás, Brazil. The research was conducted in two consecutive years, 2015 and 2016, in an Horticulture Experimental Area of the Federal Goiano Institute - Campus Morrinhos, Goiás, located at 885 meters of altitude, 17°49'19" south latitude and 49°12'11" west longitude. The crop evapotranspiration was mensured using five weighing mini-lysimeters, cultivated with one plant each. The crop coefficient was estimated through the ratio between the crop evapotranspiration of each hybrid development stage and the reference evapotranspiration estimated by the Penman-Monteith equation. Under cultivation conditions, the tomato required a replacement the 490 and 427 mm of the crop evapotranspiration accumulated, in the two years, respectively. The water needs of the hybrid vary depending on the year of planting and also on the basis of its vegetative and productive development. The estimated average crop coefficients from two years of research for cropping conditions in the Cerrado were 0.60-0.65 (0 - 10 days after transplanting); 0.88-1.00 (11 - 40 days after transplantation); 1.00-1.23 (41 - 70 days after transplantation); 1.07-1.27 (71 - 97 days after transplanting) and; 0.71-0.83 (98 - 125 days after transplanting).
