The aim of this research paper is to design a drip
irrigation system for a Pineapple orchard in the Federal
University of Technology Owerri school farm. This work takes
into account the preliminary studies of the study area
(general relief, topography and soil nature), water quality
and quantity assessment (water sample collection, testing
and analysis), soil and field analysis (moisture content
test, infiltration tests and grain-size analysis) and
climatic influence on the area to make resolute conclusions
on the parameters required for the design of the drip
irrigation system. With reference to the peak consumptive
use of pineapple (1.928mm/day) and peak potential
evapotranspiration (4.794mm/day) obtained from application
of empirical formulas; the drip irrigation system designed
comprises of 48 laterals (Inside Diameter of 10mm, 1104
emitters, Discharge of 0.012L/S, and Friction Loss of
13.44m), 1 submain(Inside Diameter of 28mm, Discharge of
0.56L/S and Friction Loss of 3.65m) and 1 mainline (Inside
Diameter of 42mm, Discharge of 0.57L/S and Friction Loss of
0.02m) with an actual emission uniformity of 85%.
