GARCIA-PEREIRA, Annia et al. Evaluation the Main Physical-mechanical Properties of Cassava (Manihot esculenta Crantz) for their Mechanization. Rev Cie Téc Agr [online]. 2017, vol.26, n.1, pp.4-13. ISSN 2071-0054.

The knowledge of the mechanical-physical properties in agricultural products has great importance to face mechanization and agro industrial process. The purpose of this research is addressed in determining the main physical-mechanical properties of cassava (Manihot esculenta Crantz, varieties La Reyna y Paigua Negra), for the mechanization of its cultivation. In the study are determined properties such as: the total mass of the plant (Mtp), length of maximum root (Lrm), average diameter of root (Dpr) and high-extraction strength (Re), among others. For processing and analyzing data the Plus version 5.1 STATGRAPHICS software was used, to look for significant differences by means of hypothesis testing. The results show that the sweet variety is significantly better than the bitter one in: total height of plant, number of buds, stem diameter, total weight of plant, number of root/plant, maximum length, diameter and soil resistance with values higher than 5%

Keywords : agroindustrial process; length; diameter of root; high-extraction strength of cassava.
