Resumen:
This work aims to develop the study of the hydraulic behavior of a
unconventional dripper working with small loads below 10 meters
water small farmer use
irrigation, providing a new alternative to drip systems.
Three types of drippers were used, one unconventional type, glass, and
two other types already marketed. These drippers were subjected to a
between 0.50 m and 6.0 m, the load ratio being determined for the three types
hydraulic - flow and pressure losses in the lateral line. The unconventional dripper
presented flow rates of 3.2 l / h at 0.50 m hydraulic load, up to 23.0 l / h at 6.0 m load,
these flows being compatible with those normally used in conventional dripping.
A project developed for I ha using the unconventional dripper in the culture of the
maize presented an initial cost within the reach of the small producer.
Commercial drippers did not perform well when working under
Cipla dripper presented highly variable flow rates
that the dripper Dangotas presented very small flow rates.
