Stage 4: Transition to Scale

This technology has been tested in Eastern Uganda and can be applied wherever farmers are using sprinkler systems on small plots.

Traditional sprinkler sets are designed for overlapping sprinklers spread over a large area for longer periods of rime. However many farmers in Uganda have small irregular shaped plots and neighbors irrigate at different times. They also are busy with other activities and do not want to have long irrigation times.



This system applies a high rate of water over a small area. This takes advantage of the high initial infiltration rate of dry soils, and is only run for short times. Farmers are able to only apply water to their own plot and use all the water delivered by a small engine pump on their own field.

Target Beneficiaries

Smallholder farmers using small engine pumps

Mission and Vision

To help make smallholder irrigation easier and take less time

Innovation Description

This system uses a connection set that joins 4 impact sprinklers together into one stand. This increases the flow rate within the normal radius for each sprinkler. Two to three of these sets are connected to a small pump, usually which can power about 8 - 12 sprinklers. The set is then placed in the center of a farmers' plot and allowed to run from 30 - 60 minutes. Irrigation should be stopped when runoff begins leaving the plot. These sets are appropriate for small plots where normal gridded sprinklers do not apply, and where farmers do not have many hours to spend on irrigation. Because water is not able to penetrate deeply in the soil, mulching is recommended with this system.

Competitive Advantage

There is no other small radius but high flow sprinkler available on the market, yet this is a demand of farmers with small plots.
