Evaluación productiva del maíz negro (zea mays l) variedad capio en el trópico bajo de la costa norte colombiana.

Abstract

The objective of this work was to evaluate the agronomic and productive behavior of Creole black corn in the low tropics of the Colombian north coast, under a design of divided plots with a total of 10 replications. Variables were measured such as: plant height (cm), leaf length (cm), leaf width (cm) leaf area (cm), stem thickness (mm), stem-leaf ratio, leaf weight (kg), stem weight (kg), capacity (kg / fv / m2). these data were taken weekly. Descriptive statistics tests and analysis of variance were applied with a significance of 5%. Where the results were obtained. Growth during the 10 weeks was 222,46 cm, stem thickness 15,575 mm, average biomass production of 11,815 kg / fv / m2, leaf weight of 2,3781 kg, stem of 5,602 kg, ears of 3, 8335 kg, in the stem-leaf ratio an average ratio of 35,7 g was obtained based on dry matter of the leaves and a weight of 51,7g of dry matter in the stem ratio. Presenting a single stem with an average of 13,8 leaves per plant and an average leaf area of 393 cm, where no significant differences were found between the treatments. Finally, the forage production obtained by the variety of black corn in the low tropics of the municipality of María la Baja-Bolívar is shown as an alternative to consider for animal feeding in Colombia.
