- Abstract
The aim of this research was to evaluate three methods to determine the water requirements of carrot (Daucus carota L.) cv. ‘Chantenay’ in Macají, Riobamba canton, Chimborazo province, Ecuador. A completely randomized block design was used and adapted to drip irrigation conditions. Three treatments and three replicates were included, according to soil moisture depletion, they were: Palabras clave: Vol. 49, No. 2, abril-junio, 120-127, 2022 Centro Agrícola Centro de Investigaciones Agropecuarias Universidad Central “Marta Abreu” de Las Villas evaporation tank 25 % (T1), FAO-56 empirical formulas 25 % (T2) and lysimeter at the time of drainage (T3). The duration of the phenological stages in the treatments was determined and the following variables were evaluated at each stage: plant height, root shoulder diameter, yield, dry matter percentage, correlation between water used and yield. Yield in the first, second and third stages and total yield were determined, in addition to the Kc adjustment in the treatments at each phenological stage. Four phenological stages were established for the crop: initial stage, development stage, intermediate stage and final stage. The results showed that the different films influenced carrot yield. In water application the best treatment was T3 with a volume of 404.76 mm, where a yield of 61.49 t ha-1 was obtained. The Kc was adjusted according to the lysimeter for each of the phenological stages: initial 0.83, development 1.06, intermediate 1.02 and the final stage 0.86, as a result of the replacement of irrigation water at the time of drainage._____________________________________________________________________
