Economic technical parameters of the central pivot Fregat in the tobacco Virginia type.

Juan, G. R., A. R. Crespo, P. R. Santana y A. Cabrera. Economic technical parameters of the central pivot Fregat in the tobacco Virginia type.

Hydraulic Engineering Vol.19 (2): 3-6, Havana, Cuba 1998.

The economic evaluation of central pivot in tobacco enterprise Sandino, municipality Mantua, province Pinar del Rio was conduced. When were used eight irrigations and a net irrigation requirement of 1503 m3/ha, was got a yield of 1.1 t/ha with an increase of 0.4 t/ha in comparison with no irrigated tobacco. The supplementary net benefit as consequence of irrigation was 229 pesos/ha and possibility and investment recuperation time of 8.1 years. To obtain highest yields will possibility a greatest irrigation profitability and will reduce the recovery time of the investment.
