Evaluación agronómica de 12 variedades de fréjol caupí (Vigna unguiculata L. Walp) en la Granja Limoncito, provincia Santa Elena.

Abstract

The agronomic behavior of 11 accessions of cowpea beans (Vigna unguiculata L. Walp.) was evaluated, with the aim of selecting the one that presents the best results in terms of yield and health in the area of the Julio Moreno parish, where Granja Limoncito, owned by the UCSG, is located. An analysis of the variables: plant height (cm), number of branches, days to flowering, number of pods per plant and number of grains per pod; was made with the objective of establishing agronomic characteristics of these lines against the witness - INIAP 463. With respect to health, damage by Cerotoma fascialis Erickson or ladybird, was evaluated in the form of percentages of affectation, being the result of CF9 statistically significant compared to the rest, with an average of 20.33 %. A cost analysis was made, based on the variety with the highest yield, of the 12 treatments under study, where a profit of USD 2 092.90 was determined for the semi-technological cultivation of cowpeas in CF8. The statistical analysis was elaborated with the Tukey Test at 5 %.
