Squash, cucumbers and cabbage crop water requirement.

Zamora, E., et al. Squash, cucumbers and cabbage crop water requirement.

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

The total water requirement of squash crop have a national average value of 1836 m3/ha, with partial water requirement of 306 m3/ha, the average number of irrigation is 5 for a crop cycle of 3 months. The total water requirement of cucumber crop have a national average value of 2150 m3/ha, with partial water requirement of 215 m3/ha, the average number of irrigation is 10 for a crop cycle of 3 months. The total water requirement of cabbage transplant have a national average value of 2097 m3/ha, with partial water requirement of 233 m3/ha, the average number of irrigation is 9 for a crop cycle of 4 months. The total water requirement of cabbage tillage, have a national average value of 3488 m3/ha.

For the calculation of project irrigation regime squash crop, cucumbers and cabbage transplant it 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.
