2014 Project update: Drip irrigation technologies in Central America and Cambodia

Description

This poster provides updates for the project called "Empowering women vegetable growers with drip irrigation," led by Manuel Reyes of North Carolina A&T State University.

The project hypothesis: "Conservation agriculture and drip irrigation will decrease labor, increase yield and income, and improve soil health." The project site: five women farmers in Siem Reap with area of 100 m2 divided into 4 plots.

The poster shares images of conventional watering, drip irrigation, tilled agriculture, and conservation agriculture.

The project used four treatments (Randomized Complete Block Design with five replications):

  • T – Tilled
  • TD – Tilled with drip irrigation
  • CA - Conservation agriculture
  • CAD- Conservation agriculture with drip irrigation

Project results:

  • Yield - lowest TD and highest CA, not significant at 5%
  • Net income – highest CA, depreciated cost of tank and drip with drip life shorter in tilled systems
  • Labor – least labor in CAD with drip as key; in CA, labor is saved by not tilling but labor is added by addition of mulch and cover crop

Impact: Reduced labor and income of $350 in 100 m2, per capita income is $944

This poster was part of the Horticulture Innovation Lab 2014 Annual Meeting, which took place March 17-21, 2014 in Hotel Real Intercontinental, Tegucigalpa, Honduras. The poster is supplemented by an additional handout that reviews the project introduction, methods, results, discussion, summary and conclusion.
