Crop yield and estimated financial return from subsurface drip irrigation for corn, cotton, and peanut over the life of the system

Abstract

Irrigation has the potential to increase crop yield and financial return on coarse-textured, coastal plain soils in the mid-Atlantic region of the United States. Although the majority of irrigation is delivered through overhead sprinkler irrigation, subsurface drip irrigation (SDI) has been shown to be a reasonable alternative to sprinkler irrigation because of its efficiency on small, irregularly shaped fields (Bosch et al., 1992(Bosch et al., 1998O'Brien et al., 1998). Increased yield and/or water use efficiency are often cited as benefits of SDI over overhead sprinkler irrigation (

Influence of planting pattern on corn response to sub‐surface drip irrigation

“…Unlike our results, Jordan et al. (2022) did not observe a difference in financial returns over the 5 years when comparing dryland and SSDI at corn prices similar to those used in the current study.…”

“…In that study, corn yield increased from 85 bu acre -1 under dryland production to 136 bu acre -1 under SSDI over the 5 years (Jordan et al, 2022). Unlike our results, Jordan et al (2022) did not observe a difference in financial returns over the 5 years when comparing dryland and SSDI at corn prices similar to those used in the current study.…”

“…(2022) reported a yield increase in 4 of 5 years when SSDI was used compared with dryland production from 2001 to 2013 at the same location with a similar SSDI system. In that study, corn yield increased from 85 bu acre –1 under dryland production to 136 bu acre –1 under SSDI over the 5 years (Jordan et al., 2022). Unlike our results, Jordan et al.…”

“…Financial return for the SSDI was $25 acre -1 ($4 bu -1 ), $128 acre -1 ($6 bu -1 ), and $210 acre -1 ($8 bu -1 ) greater than financial returns for dryland production (Table 4). Jordan et al (2022) reported a yield increase in 4 of 5 years when SSDI was used compared with dryland production from 2001 to 2013 at the same location with a similar SSDI system. In that study, corn yield increased from 85 bu acre -1 under dryland production to 136 bu acre -1 under SSDI over the 5 years (Jordan et al, 2022).…”
