Much of the success in growing wheat plants depend upon preparing the kind of seed bed which will give the plant good start, seeding correctly, and cultivating the crop which need it after coming up. While in the warmer districts in this country, there is no timme to practice a correct preparation of seed bed, in order to short the time after the harvest of preceding rice crops, so that the start of tillering is evidently later than that of cooler districts. In order to determine what effects the small ridge of soil had on wheat plants, we heaped up the soil at the north side of the seeding stripe at the time of soil preparation. In the early stage of growth, the number of tillers of wheat plants in the plot mentioned above was larger than that of control one, as shown in the figure. While in the later stage of growth, the number of tillers in the former plot became less than the latter. This difference in number of tillers in adult stage, was induced by the depth of crown of seedlings under the soil surface, which has been deeper in the case of protected plants, than the control one, owing to gradual collapse of soil ridge by wind and rain.
