Show DEPTH TO CULTIVATE CORN Task Has Much to Do With Yield-Results Yield-Results of Experiments Made at North Dakota Station. The depth at which corn is cultivated culti-vated has a good deal to do with the yield. A plant sends its roots as near the surface as it can find moist soil. When the cultivation is shallow, the roots can come quite near the surface sur-face without being disturbed. When the cultivation is deep a number of the roots are cut and the plant retarded. re-tarded. At the North Dakota experiment station trials have been made in cultivating culti-vating corn shallow and deep. The yields were 5 1-10 bushels more on the shallow-cultivated. The shallow cultivation also saves work in cultivating culti-vating or makes it possible to get over more field in a day, and the weeds can be kept down as easily by the shallow cutivation as by the deep cultivation, if done at the proper time. |
