Frecuencias de riego para cultivo de cacao (Teobroma sp) en fase de desarrollo para la época seca.

Abstract

The use of irrigation systems in the cultivation of cocoa is established as the basis of the new climatic dynamics. The research was carried out in a crop of (Theobroma cacao L) CCN-51 in the development stage during the dry season in the Barraganete parish, Pichincha canton, Manabí Province with the objective of evaluating three irrigation frequencies in the crop. of cocoa in the development phase during the dry season. Three treatments and a control were established: two irrigations per day, one irrigation per day, passing one irrigation day; control=without irrigation, plant height (m), stem diameter (mm) and number of suckers were evaluated. A completely randomized design was applied and analysis of variance was performed with p<0.05 and the Tukey significance test to determine differences between means. At 60 days the height of the plant does not establish significant differences between the treatments, the highest average in plant height is reported by the T1 and control treatments (1.35 and 1.37 m) respectively. In the diameter of the stem, T2 obtained the highest mean (5.18 mm) and the control treatment the lowest (4.31 mm), the use of T1 after 60 days allows the growth of suckers with an average of 3 suckers per plant. It is concluded that using two irrigations per day in the crop is a viable option to increase the number of suckers and plant height.
