The experiment studied how wheat and barley plants grow and produce grain under specific planting conditions. They found that the main stem had the most ear-bearing tillers, followed by the first, second, and third tillers. Barley leaves emerged in a pattern similar to previous theories, while wheat tillers had more leaves than expected. Nitrogen levels in leaves decreased as the plants grew, with higher-order tillers having the most nitrogen. In terms of grain weight, the main stem contributed the most to overall grain yield, followed by the first and second tillers, with the third tiller having the least impact.
