Technical Abstract: Surface drip irrigation laterals were spaced next to crop rows (0.91 m) and in alternate row middles (1.83 m) to document crop yield and partial net economic returns compared with non-irrigated peanut (Arachis hypogaea), cotton (Gossypium hirsutum), and corn (Zea mays). A drip irrigation system was installed at two sites, for three years (2002 to 2004) in a randomized block design. Surface drip irrigated peanut had greater yield (4900 kg/ha), market grade (74%), and gross revenue ($2000/ha) compared with non-irrigated peanut (4066 kg/ha, 71%, and $1570/ha), respectively. Drip tubing in peanut spaced at 0.91 m is not cost effective while those spaced at 1.83 m returned an average $120/ha compared with non-irrigation. Drip tubing space at 0.91 and 1.83 m had similar corn yield (10,555 kg/ha) and was significantly greater than the non-irrigated areas (5,562 kg/ha). Drip tubing spaced at 0.9 m in corn had a net loss in revenue compared with non-irrigation. The 1.83 m spaced laterals in corn had $196/ha greater net revenue compared with non-irrigation. Cotton lint yield averaged 1194 kg/ha for 0.91 and 1.83-m lateral spacing and was almost two times greater than non-irrigated lint yield. Cotton gross revenue averaged $1200 and $600/ha for irrigated and non-irrigated treatments, respectively. Cotton net revenue was $613 and $969 for 0.91 and 1.83 m lateral spacing, respectively. The 0.91-m lateral spacing may not be cost effective for peanut, corn, or cotton. Conversely, the 1.83-m lateral spacing may be cost effective for peanut, corn, and cotton.
