Energy balance of tillage for the cultivation of tomato (Lycopersicon esculentum Mill.) in the UEB Protected and semiprotected crops of Veguita

Abstract

The investigation was the developed in the Unit of Base “Protected Cultivations and protected” Semi belonging to the Agricultural Company “Paquito Rosales Benítez" of Veguita, municipality Yara, county Granma. The objective of work was to evaluate through the proposed methodology for Bowers (1992) the energy of direct and indirect use once the cultivation of the cultivation of tomato (Lycopersicon esculentum M.) was associated to in Fluvisol. The energy of direct use yielded value 784,9 MJ ha-1, being once the fuel followed of the related by force was associated to the bigger quantity human, which represented the 62,7 % and 30,6 % respectively of the total. You had 338,1 MJha-1 behavior as well as the energy of indirect use is, correlating the bigger percentage rotovateado's work with the 45.3 %, being the acanterado the one that minor incidence yielded with 1,7 % of total. The productive process of cultivation incurred in 634.9 CUP expense, having an effect on bigger quantity the expense by way of salary that you represented 96.1 % of the total.
