Evaluación de la aclimatación y rendimiento de 8 cultivares de brócoli (Brassica oleracea L.Var. Itálica), a campo abierto, en la comunidad La Josefina, cantón Guano, provincia de Chimborazo

Abstract

The current research aims to assess the acclimatization and 8 yield broccoli cultivars (Bassica oleracea L Var Italic) in open field in La Josefina community, Guano canton, Chimborazo province. A randomized complete block design with 8 treatments and three replicates was used. Parameters such as: height, number of leaves, days in the formation of curd and harvest, characteristics of the curd as (diameter, color and weight), yield Kg,ha and the economic analysis was performed according to the cost-benefit ratio, AVENGER and TLAHUAC cultivars shown the best results for plant height with averages of 48. IOcm and 47.37cm respectively. While SUPREMO cultivar shown the best results in number of leaves with an average of 13.20 leaves. TIAHUAC, DOMADOR, HMX4140Fl cultivars shown the lowest number of days in the formation of curd and harvest, with averages of 85.85 and 84.33 days at harvest respectively. Respect to the characteristics ofthe curd: the best diameter and greater weight of the curd was presented by TLAHUAC cultivar with 15.05 cm and an average Of 412.90 g respectively; SUPREMO cultivar presented better color of the curd. TIAHUAC cultivar shown the highest yield With an average of 22958.53 kg,'ha. And finally when the economic analysis was carried out, TLAHUAC cultivar presented the highest benefit/cost with a profit of S l. 14 for every dollar invested which is equivalent to 114%. t is recommended to cultivate TL„AHUAC cultivar in La Josefina community based on an economic and agronomic standpoint, because it presents a good physiological and morphological characteristics, as well as better yields and profitability.
