The main source of gluten is wheat, but the prolamins in rye and barley are also toxic and must be avoided.
Grain cereals (wheat, oat, rye, triticale, barley, spelt) were produced for feeding and sometimes also sold as cash crops for human consumption.
Changes in crop balance, principally the reduction of fallows and rye, and the later development of potato cultivation, explain much of this.
There were no significant interactions between soil type and rye cultivar.
Second, we conducted our experiments with three rye cultivars.
For example, i1 could be rye bread, and i2 could be bread, in the example of market basket analysis.
However, inferior cold tolerance of black oat compared to rye may limit its zone of utilization.
Of the crops tested, oat and rye grass yielded much more, on average, than the other crops.
