Function of water consume and the tobacco harvesting in Cuba.

Alvarez V. P. and G. R. Juan. Function of water consume and the tobacco harvesting in Cuba.

Hydraulic Engineering Vol. 19(2):23-25, Havana, Cuba 1998.

The relation water requirement and the harvesting in four tobacco varieties, using four level moistures in the soil: low, medium, optimal and high was studied. Equations of regression: lineal, normal exponential, modified exponential, normal potential, logarithmic, quadratic, radical and cubic was analyzed and was found that the more significant is represented for the function cubic, quadratic and radical and their the most significant belong to the cubic with a correlation coefficient for the different varieties from 0.96 to 0.84 and demonstrated that tobacco respond well to the irrigation and a bad water management by excess or deficit decrease the yields.
