The work was carried out in the Valle del Yabú Agricultural Company located in the municipality of Santa Clara, Villa Clara province with the objective of determining the efficiency in the use of irrigation water, in the aforementioned company, through the calculation of the productivity of the water applied to some crops of economic importance. The productivity of the water applied by irrigation, the productivity of the total water, and the total water applied (T), in the corn, potato, dasheen, beans and sweet potato crops were calculated. In the sweet potato the productivity of water applied by irrigation, 20 kg / m3, was higher than that of the rest of the crops. In the potato the average was 7.74 kg / m3, in the bean it reached values ​​of 4.74 kg / m3, in the case of the dasheen it was 3.92 kg / m3 and the corn was 10.66 kg / m3 The results showed a low productivity and inefficiency in the use of water for potato, bean and corn crops, not the case of dasheen and sweet potato where water productivity values ​​were obtained that show an efficient use of water in these crops.

El trabajo se realizó en la Empresa Agropecuaria Valle del Yabú ubicada en el municipio de Santa Clara, provincia Villa Clara con el objetivo de determinar la eficiencia en el uso del agua de riego, en la referida empresa, a través del cálculo de la productividad del agua aplicada a algunos cultivos de importancia económica. Se calculó la productividad del agua aplicada por riego, la productividad del agua total, y el agua total aplicada (T), en los cultivos maíz, papa, malanga, frijol y boniato. En el boniato la productividad del agua aplicada por riego, 20 kg/m3, fue superior a la del resto de los cultivos. En la papa el promedio fue de 7,74 kg/m3, en el frijol alcanzó valores de 4,74 kg/m3, en el caso de la malanga fue de 3,92 kg/m3 y el maíz fue de 10,66 kg/m3. Los resultados mostraron una baja productividad e ineficiencia en el uso del agua para los cultivos de papa, frijol y maíz, no el caso de la malanga y el boniato donde se obtuvieron valores de productividad del agua que muestran un uso eficiente del agua en estos cultivos.
