DEVELOPMENT OF A SUBSURFACE PERFORATED PIPE IRRIGATION SYSTEM

ABSTRACT The study focused on the design and installation of a subsurface perforated pipe irrigation system, aimed at developing a subsurface perforated pipe irrigation system. The design parameters include the irrigation field area, soil type, available water source, and crop spacing, among others. The installation process was documented through various illustrations showing the components of the system. Soil physicochemical properties were analysed, revealing that the pH levels ranged from 5.9 to 6.3, which is within the acceptable range for agriculture. Electrical conductivity was below FAO standards, indicating suitable soil conditions. However, total alkalinity exceeded recommended limits in most samples, and calcium hardness levels were low, potentially affecting soil structure. Additionally, the physicochemical properties of the irrigation water were assessed. While the water temperature and pH were within acceptable ranges, calcium concentration and total alkalinity were above recommended levels, which could lead to issues such as scaling in irrigation systems and reduced nutrient availability in the soil. Overall, the findings suggest that while the irrigation system design is effective, management practices should be implemented to address high alkalinity and calcium levels in both soil and water to ensure optimal crop growth.
