Álvarez V. P., G R. Juan, C. A. Díaz, A. M. García. Response of tobacco technical nursery to the drips and microjet irrigation.
Hydraulic Engineering Vol.20 (1): 46-48. Havana , Cuba 1999.
In Havana province the localized irrigation in tobacco technical nursery, in which phlegm was employ as subtract, using two treatment with microjet and two with drips, was studied. Difference highly significant in the irrigation techniques analyzed was obtained, meeting that the greater production of seedling was obtain when the water was delivered with microjet of 1 mm x 180º with a discharge of 39 L/h, and a pressure of 1.5 kPa, spacing to 1,4 m , for an average yield of 635 useful seedlings for square meter.
The smaller production of seedling belong to the drip treatment due to moisture pattern obtain in phlegm was very poor.
