About one week after harrowing, the plants in each area were counted again and the loss due to har- rowing was determined. On the basis of the figures obtained, the stand was 218,000 plants per acre before and 193,000 plants per acre after harrowing, a loss of 25,000 plants, or per cent. This loss alone would allow the plants greater freedom for development, and it might be expected to increase the number of culms per plant. To determine the effect of harrowing on the production of culms the total number per unit area was determined just before harvest and the average number of culms per plant calculated. The average.
