COMPARISON OF SUBSURFACE DRIP AND FURROW IRRIGATION OF COTTON ON TWO SOIL TYPES USING DEEP EVERY – OTHER FURROW PLACEMENT OF DRIPPERLINE

W.R. DeTar and C.J Phene

OBJECTIVES: To compare subsurface drip to furrow irrigation of Acala cotton on a good soil (uniform, high silt content) and a poor soil (non-uniform, sand streaks and pockets) , by measuring growth characteristics, yields, and water use. Also to verify technical feasibility of drip irrigation and to determine problem areas.

PROCEDURES: Equipment procurement and installation began in the Fall of 1989 for a 1.2 ha field located near the southwest…
