Behavior of three systems of growing labor for the production of tomato (Licopersicum Esculentum Mil) (Original)

Abstract

The work was carried out in the UBPC Antonio Maceo belonging to the Company of Several Cultivations Paquito Rosebushes Benítez of the municipality of Yara, county of Granma. It was carried out with the objective of evaluating three technologies (T1, T2 and T3) for the cultivation works in the tomato production, in two campaigns (December 2012 March of the 2014), keeping in mind the productivity and the consumption of fuel. The used method was the analytic one investigative and the applied technique the fotocronometraje, based on the norm brunch XX1: 2005. The best results in the evaluated indicators corresponded to the technology of minimum laboreo T3 with multiple tier BP-206: productivity for hour of clean time (2,67 ha h^-1) and of operative time (2,20 ha h^-1) with significant differences regarding the rest of the evaluated technologies, as well as the smallest consumption of fuel (5,20 L ha^-1); he/she decreases this in a percentage of a 53 and 42 % regarding T2 and T1.
