| You are asking a good question :)
The no-till beans were planted earlier (5/23 vs 6/3) which may give them a little more yield potential but the tillage beans are actually a little taller now.
Most of the no-till beans are an older variety (BR 34A7) that is very tall and leafy and has performed well for us in no-till plots for more than a decade but may have less yield potential than the 360GH planted in the adjacent tillage bean study. We included 36 rows of 360GH in the no-till study so we will be able to compare no-till vs. tillage with the same genetics.
The no-till beans were planted at a higher population (195k) than the tillage beans which are a population study comparing 175k vs. 145k.
The no-till beans will likely have no other costs until harvest whereas the current plan is to cultivate the tillage beans 1 more time.
Ultimately weather in August may impact yield more than anything you can see right now but I think there is good potential for both the no-till and tillage bean plot yields to average over 70 bu/a.

Beautiful day for cultivating :)
