Castellanos A. E., Zamora, E., et al. Sweet potato crop water requirement.
Taken from: Juan G. R., Dehoguez G. E. and Tzenova L. The Irrigation, Page: 125-137, Havana, Cuba, 1996.
To calculate the project’s irrigation regime in the Sweet potato crop was used the year of 25% probability of total water requirement, calculated from time series of rainfall and evaporation no less than 20 years. In implementing the work, it was used basic information: precipitation and evaporation analyzed every ten days, hydro properties of soils, bioclimatic coefficient “K”, technical culture specifications and a computer program to calculate the different components of the irrigation regime. The balance of the information is made for crop life cycle.
The total water requirement of the Sweet potato crop in winter planting have a national average value of 3372 m3/ha, with partial water requirement of 281 m3/ha, the average number of irrigation is 12 for a crop cycle of 4 months. The total water requirement of the Sweet potato crop in spring planting have a national average value of 1095 m3/ha, with partial water requirement of 219 m3/ha, the average number of irrigation is 5 for a crop cycle of 4 months
