| Phil N - 11/6/2012 06:28 I agree if yields are 30-40 bu/ac or less, there is no advantage to narrower rows, but what if you get above average rainfall next year. You don't want row spacing to be a limiting factor do you? I Phil N http://www.needhamag.com Point taken. However, there is the flip side of the coin in that narrower rows destroy more residue during the seeding operation, and in western Neb, KS, Tx & Okla panhandles, etc., they need every scrap of mulch cover they can get (keep). In these regions, quantity of mulch cover strongly correlates (positively) with dryland wheat yields. And, there often are multi-year effects from additional residue preservation. And, with 10" spacing or wider, it becomes possible to use RTK to stay off the previous year's stubble and plant between the rows -- the effect of keeping stubble standing has major benefits, not only in the mulch effect, but in reducing wind erosion.
