Evaluación del comportamiento de variables agronómicas del cultivo de cacao (Theobroma cacao L) clon CCN51 utilizando dos sistemas de riego en la Hacienda Maquencal - Municipio de La Jagua de Ibirico - Cesar.

Abstract

The purpose of this study was to evaluate the agronomic behavior of Theobroma cacao L. A free exposure crop planted in two fertigation systems (drip and micro-sprinkler) that will be evaluated in two phenological stages according to the BBCH scale (stage 1, 6), with the purpose of measuring the agronomic response in terms of the development of the leaf area for stage 1 and percentage of flowering in stage 6. This study is made up of two treatments, T1 (treatment 1 micro-sprinkler irrigation), and T2 (treatment 2 drip irrigation), which in turn each treatment is made up of 13 trees that total 26 trees, later it was chosen as a unit One tree was experimentally tested, and five floral bearings and five vegetative shoots were taken as samples from each experimental unit, which were followed up throughout the study where agronomic variables were measured, such as leaf area for the vegetative stage and the percentage of flowering for the reproductive stage. In order to contrast the agronomic yields of each treatment, in response to the drip and microsprinkler irrigation system, and thus be able to obtain the response of which irrigation is more suitable for the environmental conditions that occur in the Maquencal farm, located in the municipality of Jagua de Ibirico in the department of Cesar.
