    Determinación de los requerimientos hídricos del cultivo de brócoli (Brassica oleracea L. Var. Avenger) bajo condiciones edafoclimáticas del cantón Cevallos, Provincia de Tungurahua

    Broccoli (Brassica oleracea L.) Var. Avenger is a vegetable of great importance in Ecuador, specifically in the provinces of Cotopaxi and Tungurahua. This research had as its central axis the determination of the crop's water requirement; soil water parameters; biometric parameters of the plant and its cultivation coefficient (Kc). The research was carried out at the Querochaca Experimental Farm, Technical University of Ambato; located in the canton of Cevallos, Province of Tungurahua. An area of 389 m2 was selected which was delimited for two treatments, each treatment had 3 experimental plots of 60 m2 with 10 sample plants. The results obtained were as follows: water requirement during the entire crop was 218 mm for Treatment 1 and 252.5 mm for Treatment 2. The soil water parameters yielded a field capacity (CC) of 15.1%, permanent wilt point (PMP) of 7.28% and bulk density (DA) of 1.55 g cm-3. The biometric parameters in Treatment 1 (Penman-Monteith method) obtained an average final height of 55.96 cm, with an average of 13 leaves, a yield of 11.48 t ha-1, a root volume of 58.66 cm3; for Treatment 2 (evaporimeter tank method) the final average height of 68 cm, with an average of 15 leaves, a yield of 24.75 t ha-1 and a root volume of 82 cm3. The culture coefficient (Kc) for Treatment 1 was 0.73 in the initial stage, 1.02 in the development stage, 0.43 in the intermediate stage and 0.11 in the final stage; for Treatment 2 it was 0.58 in the initial stage, 1.06 in the development stage, 0.56 in the intermediate stage and 0.32 in the final stage.
