• Physiologically optimal hard red winter wheat (Triticum aestivum L.) plant spacing is achieved by equalizing between‐row and average‐within‐row seed placement distances. Commercial grain drills that are used on most farms in Oklahoma have row spacings that are too wide for physiologically efficient seeding. This study was conducted to determine if an ultranarrow row (UNR) grain drill with 3‐in. row spacing would be economical for farmers. A representative farm approach was used to estimate the economic consequences. Estimates were computed for farm sizes of 300 and 1000 acres, for both conventional and UNR production systems. The minimum yield increase required to offset the estimated increase in the cost of the UNR drill, and the maximum UNR drill price given the anticipated yield increase were computed. At the budgeted prices and input levels, the UNR drill would increase returns by $6.79/acre for the 1000‐acre farm and $6.03/acre for the 300‐acre farm. Yield increases of 1.40 and 1.08 bu/acre would be required for the UNR system to break‐even with the conventional drill system for the 300‐ and 1000‐acre farms, respectively. Given the estimated yield increase of 4 bu/acre, the 300‐acre farm could pay $28 469 for a 13‐ft UNR drill, and the 1000‐acre farm could pay $68 997 for a 26‐ft UNR drill, for the UNR system to break‐even with the conventional drill system. The UNR technology appears to be a promising economical alternative for hard red winter wheat producers in the Southern Plains.
