Water requirement of the onion crop Red Creole variety

Leon M., Zamora, E., et al. Water requirement of the onion crop Red Creole variety.

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

To calculate the project’s irrigation regime in the onion 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 onion crop of the Red Creole variety, have a national average of 4 136 m3/ha, with partial water requirement of 188 m3/ha. The average number of irrigation is 22 for a crop cycle of 5 months. The onion is grown in different agricultural regions of Cuba during the dry season, generally from November to April.
