OBJECTIVES: To evaluate various subsurface dripperlines for use with cotton on a very sandy soil, by measuring uniformity of emergence, plant growth characteristics, yields, and changes in flow rates.
PROCEDURES: Table 1 shows the various combinations of tubing types, depth of placement, emitter spacing, discharge rate, and wall thickness for some of the companies that felt that their product was suitable for subsurface drip irrigation of cotton.
