Since some of you guys are new, I just want to point out that you don't compare the cost of seed by weight. If you find two different crops that otherwise achieve your objectives and it comes down to cost, you need to compare the cost on a per acre basis. There are several things to take into account. One is seeding rate. Not that buckwheat and winter rye fill the same niche, but I'll use them as an example since folks mentioned them. The seed rate for buckwheat is 40-55 lbs/ac. The seeding rate for Winter Rye is roughly 60-120 lbs/ac. So, if you only look at seed cost, you can pay about twice as much for Buckwheat as Winter Rye for the same cost per acre. Around here Winter Rye is $18-$23 depending on whether you get VNS or a named variety.
Next, consider total cost. Lime, fertilizer, maintenance, fuel, Herbicide, etc. In these areas, these two crops are not much different but with other crop choices it can be significant. Something like alfalfa is sensitive to pH and fertility where buckwheat and WR are not, so lime and fertilizer costs can make a difference on the per acre cost. If one compares Buckwheat to many other warm season annuals (sunflowers, soybeans, ...), there can be a significant difference in herbicide costs. Buckwheat is so fast to germinate, if planted in a clean field, it will outcompete most weeds with no herbicide. Many of the alternatives are much slower to germinate and grow. In my area, for example, between the browse pressure caused by high attraction on soybeans or sunflowers and the weed competition, many fewer plants make it to full establishment. There are also termination costs with some crops. For example, in my area, PTT must be terminated in the spring before it bolts. Gly won't do it, so you either have other herbicide costs (or in my case) you have the fuel and time cost of mechanically terminating them with a till. With only a small no-till drill that does not handle trash well, I also need to bushhog corn stalks (corn gone by then) at the end of the season so they have contact with the soil and time to decompose before the spring plant.
This is just a set of examples, but the key point is that you need to look deeper when comparing cost.
Thanks,
Jack
