Use of animal traction in the cultivation of tobacco (Nicotiana tabacum L.) (Original)

Abstract

The present work was developed in the Cooperativa de Créditos y Servicios (Cooperative of Credits and Services) “General Ramos", which is part of the Empresa de Acopio y Beneficio del Tabaco (Company for the Storing and Benefit of Tobacco), located in the area of Gallardo, via Santiago de Cuba, in the municipality of Bayamo, province of Granma. The aim of this work is to compare three in- between- rows cultivation works with animal traction in tobacco plantings, by means of the use of the wooden plow, the 6 in 1 chisel plow and the three work organs cultivator, all them of animal traction. As a result, T3 was the one that reached the biggest productivity per hour of clean (W_TP), operative (W₀₂) and productive (W₀₄) time, as well as time without shortcomings (Wt) and exploitation (W₀₇). The biggest work depth was achieved with T1 (14 cm), while with T3 the biggest work width was reached (90 cm) along with the exploitation of the work width (β). The highest work speed was reached with T3 (2,75 km h^-1 ) for a 90% use of work speed. The thickest shafts were reached with T3. Treatments T2 and T3 reached the lowest direct exploitation costs.
