PACHECO SEGUI, Juan y PEREZ CORRA, Andrés. Evaluation of the irrigation management in potato in the Enterprise of Tilling Several "Valle del Yabu", Santa Clara, Cuba. Rev Cie Téc Agr [online]. 2010, vol.19, n.3, pp.47-52. ISSN 2071-0054.
The objective of this paper was the evaluation of the irrigation technology and the irrigation regime applied to the crop of potato in the field 14 of agricultural cooperative #2 belonging to the enterprise "Valle del Yabu" during the period 2008-2009. The irrigation technology was an electric central pivot model Western, which worked with good uniformity. The applied water depths were in general very small and with very short irrigation intervals those regime caused an excess of turns of the central pivot in the field, with problems of blockages and wash of chemical products. The soil moisture was measured by means of soil samples, tensiometers were also installed. The depth of 273 mm of water applied in the whole cycle was enough for the crop, but deficiently distributed. Starting from the water balance, the irrigation depths were recommended by phenological phases and also the irrigation intervals. The yield of tubers was of 30.37 t/ha with favorable economic indicators for the UBPC #2.
