Effetto della pacciamatura sui consumi idrici e sulla programmazione irrigua del melone (Cucumis melo L. var. Inodorus) in condizioni di pieno campo

We report the results of a lysimetric study carried out on melon in order to verify the criteria of calculation of evapotranspiration proposed in the new Irrigation and Drainage FAO paper 56. Without mulching, the new Kc proposed resulted in a reliable estimation of evapotranspiration, correcting the overestimation of 42% obtained when using the old Kc. With mulching, an underestimation of the proposed kc gave as result an underestimation of 35% of the water use and irrigation volumes.
