Evaluation of technological indicators and of exploitation of the groups of machines used in two technologies for the farm of the tomato cultivation (solanum lycopersicum l) (Original)

Abstract

The investigation was developed in the Basic Unit of Cooperative Production (UBPC) "14 of June" belonging to the Agricultural Company "Paquito Rosales Benítez" of Veguitas, municipality Yara, county Granma. The objective consisted on evaluating the groups of machines used in two farm technologies (T1, T2) for the tomato cultivation (solanum lycopersicum l.) in Fluvisol, keeping in mind the behavior of the technological indexes - explotativos and economic. When comparing the obtained results they were significant differences among the two technologies (treatments), contributing the best results T2 with use of the width and speed of work of 0,94 and 0,87 respectively, skating of the propellers 11,90 %, productivity for hour of clean time 1,21 ha h^-1, smaller consumption of fuel 36,75 L ha^-1, being the most rational with a cost of 107,75 CUP ha^-1.
