| Study Title |
Low cost auto irrigation system for home gardens intensification to minimize the agro-climatic risk. |
| Study Region |
Matara District, Southren Province, Sri Lanka |
| Problem Statement/Central Research Question |
Risk in climate variability for home garden crop production within the area. Lack of appropriate irrigation systems affordable to farmers with in the area. |
| Relevance of the question/hypothesis |
Identify the optimum cropping calendar and planting time of vegetables for home gardens. Design and test an appropriate low cost irrigation system for home gardens using roof runoff water.
|
| How the question/hypothesis is researched |
Daily rainfall data over 45 years in different regions of the district was assessed to understand the climatic risk on crop production and the optimum cropping calendar that needs less water for irrigation. An appropriate low cost auto irrigation system was designed with clay pots and emitters to use roof runoff water for irrigation.
