Validación de modelo alométrico para estimar la producción de biomasa en cultivares de cacao (Theobroma cacao L.) tipo nacional y de origen trinitario (CCN-51) en la zona norte de la provincia de Los Ríos.

This research was carried out in two locations (Valencia and Venetians), from August 14, 2017 to August 20, whose objective was the "Validation of allometric model to estimate the biomass production in cocoa cultivars (Theobroma cacao L.) National Type and Trinitarian origin (CCN-51) in the northern area of the province of LOS RIOS ". Factor A with two localities, (Venetians and Valencia) Factor B with two types of cacao (National and Trinitarian CCN-51) and four replicates were used for the study. The variables that we took in the investigation were: Length, diameter, surface, volume, fresh biomass. For the length variable vegetative structures, there were no significant effects on local factors and cocoa types (P> 0.05), the total length that was the product of the sum of the length reached at the trunk level, primary branches , secondary and tertiary, in localities (Valencia’s and Venetians) with a total of 495 and 461 cm tree-1, while in cocoa types did not show significant differences with a total of 506 and 450 cm tree-1 and in the variable of diameter of the vegetative structures did not show significant differences in the cantons (Valencia and Venetians) was of approximately 8.25 and 8.08 cm tree-1, while in the analysis of cacao types a total of 8.63 and 7.71 cm tree-1 was obtained. In the surface variable, there were no significant differences (P> 0.05) in localities with a total of 26.66 and 21 dm2 tree-1 and in cocoa types with a total of 27.03 and 20.63 dm2 tree-1 in the volume variable in locality did not show significant differences (P> 0.05) with a total of 13.76 and 9.21 while in cocoa types if showed significant differences (P <0.05) in a total of 14.98 and 7.99. In the variable of fresh biomass, there were no significant differences (P> 0.05) in either of the two or in localities with a total of 41.98 and 33.82 or in types of cocoa with a total of 42.8 and 33.01 while in the variable dry biomass only showed significant differences (P <0.05) in cocoa types with a total of 24.87. In the biomass supernumerary branches measured (kg MF tree-1) and estimated biomass (kg MF tree-1) were not similar since the points of (observations) are clearly distributed above the dotted line one by one. The points of (observations) are clearly distributed above the dotted line one by one.
