Water requirements of bean crop in the conditions of Cuba.

Giralt E., Zamora, E., et al. Water requirements of bean crop in the conditions of Cuba.

Taken from Juan G. R., Dehoquez G. E. and Tzenova. L. “Irrigation.” Page.125-137, Havana, Cuba, 1996.

To calculate the project’s irrigation regime of bean crop was used the year of 25% probability of the total water requirements, calculated from decennial historical rainfall and evaporation not less than 20 years. In carrying out the work using information on precipitation and evaporation, hydro physical properties of soils, bioclimatic coefficient “K”, technical specifications of cultivation and a computer program to calculate the various elements of the irrigation regime.

The balance of the information held for the life cycle of the crop.The total water requirements for the cultivation of long-cycle beans have a national average of 3553 m3/ha. The average number of irrigation is 14 for a life cycle of the plant 120 days with a partial net water requirements average of 254 m3/ha.
