Urban Farm DB summary

This intervention study assessed subsurface clay pot irrigation versus traditional hand-watering basins in 12 primary school vegetable gardens in Tanzania's Dodoma Region. Clay pot irrigation significantly increased mean water use efficiency by 65% and marketable amaranth yield by 42%. Tomato yield showed a positive but non-significant trend, and qualitative feedback indicated reduced labor burden for students.
