The following general information’s are required for designing a drip irrigation system:
1. Water Source:
The source of water is usually a well or a tank storing rainfall runoff.
2. Types of Crops:
Different crops required different plant spacing and irrigation requirement. The general layout of the system and especially the emitter were depending on the type of soil and type of crop.
3. Topographic Condition:
It is necessary to know the general land slope determine the size and location of mainline and sub main.
The soil infiltration rate, water holding capacity, texture and structure and bulk density must be known when selecting emitter type, determining spacing and setting up irrigation schedules.
5. Climate Records:
The climatic records will shown when and how often irrigation is needed in various season of the year.
