Studies on the Plowing upon the Cultural Technics in Paddy Field : (2) The effect of simplified method of seeding and plowing upon the growth of the winter wheat or barley in paddy fields

[摘要] For the purpose of simplifying the seeding of the winter wheat or barley in paddy field, a method putting the mannures and seeds into the soil by plowing with Rotary power tiller was examined. Results obtained were as follows: 1) On the new method, as the depth of plowing became deeper, the number of plants was less numerous per unit amount of sown seeds. Compared with the plant growth by the common method, the growth by the new method was slower in early stages, but the weight of grains was heavier than that of the common method. 2) In case of properly adjusted number of spiks by the amount of sown seeds and depth of plowing, the weight of grains of the simplified method was much increased than that of the common method
