Elements of farm practice, prepared Elements of farm practice, prepared especially for teaching elementary agriculture; elementsoffarmpr01wils Year: 1915 Figure 53.—Seeds of (1) wild pea or vetch; (2) wild buckwheat; (3) Ragweed or King- head; (4) corn cockle. by buying or using seed grain that contains these weed seeds. The weeds in each year's crop may be lessened noticeably by sov/ing only grain free of weed seeds. Farmers should be able to recognize the weed seeds found in grain, so that they may not buy and use seed grain that contains seeds of dangerous weeds. Description.— Below is given a brief descrip- tion of five kinds of weed seeds most commonly found in grain: Corn cockle or blue cockle is a rough, black, somewhat triangular seed, about as large and heavy as a kernel of wheat. It is common in seed wheat, as it is hard to separate these seeds from the grain. See Figure 53. Ragweed or kinghead is a dark brown heavy seed. The seeds vary in size from slightly smaller to consider- ably larger than a kernel of wheat. They are easily recog- nized by the crown-like appearance of the tip. The seed is smaller at the base, with several ribs extending length- wise and terminating in as many points around a central point in the tip, giving it the crown-like ap- pearance mentioned. It is common in grain in the Red River Valley. See Figure 53. Wild oats may be distinguished from com- mon white oats by the following points: Wild oats are darker in color, are more slender, have a small tuft of hair at Figure r,4.—Seeds of (1) wild oat;^; (2) tame tllC baSC and liaVC a
