Problem

Many farmers use small engine pumps to irrigate vegetables by placing pipes in the plot and allowing water to flood. This results in poor uniformity, very high labor requirement, and damage to the crops.

}

Solution

This system pumps water through a buried mainline, and uses a layflat pipe to fill furrows directly within each farmer's plot, minimizing the seepage losses in canals while maintaining the benefits of furrow irrigation.

Target Beneficiaries

Smallholder farmers

Mission and Vision

To reduce labor, water loss and crop loss among farmers using small pumps in flat areas.

Innovation Description

This system pumps water through a buried mainline, and uses a layflat pipe to fill canals within the fields to be irrigated. The plots are first leveled and furrrows made perpendicular to the main pipe. Take-off points are spaced on the main canal at 60 meters, with connections for the layflat pipe. This pipe then goes to the edge of a plot, where a farmer will have set a feeder canal for their furrows. Alternatively, a farmer can fill each furrow one by one with the pipe directly. Farmers use cutback irrigation, allowing the water to reach near to the end of the furrow before closing it and adding water to the next. This improves water application efficiency. Often this is done in sets of 3-4 furrows at a time to ease labor of opening and closing furrows.
