Phil, would you ever recommend 10" spacing over the 7.5" on an 1895? I have the openers available to add to my 1895 to convert from 10 to 7.5 and have been curious about this.
In my personal opinion the spacing doesn't matter as much as some people will make you think. I think it comes down to moisture and weed control but not so much yield. There was a test plot I was reading a summary on where 15" wheat out yielded it's narrower peers and obviously that's not gonna happen every time but I think it proves that it's not worth bending over backwards to get yourself narrower rows
I had a test plot with 7.5 and 10" spacing. This was a yield of just under 100 bu/ac. The 10" made a few bushels more probably because it had less disease pressure.
There are numerous replicated wheat row spacing studies conducted across the US. Almost all of them show a significant yield increase as the row spacing is decreased. In fact 5” rows have shown to yield significantly more than 7.5” rows, and 7.5” rows yield more than 10” rows. One of the most comprehensive data sets was summarized by Dr Randy Wiesz at NCSU. It summarized 35 different replicated university row spacing studies into one graph, and it shows the narrower the rows the higher the wheat yields.
