Field beans yield

Field beans grow well on clay soils and heavy loams, provided they are well-drained and limed (pH above 6). Winter beans are not frost hardy and so are risky to grow, north of the Midlands. In some rotations, beans replace the clover break and they are usually followed by wheat. Yields for spring and winter field beans are shown in Table 5.4. The problem with field beans is their variable yield, which is partly caused by adverse weather conditions and susceptibility to pests and diseases (winter beans get chocolate spot, spring beans are aphid prone), and partly due to the uncertain activity of the necessary insect crosspollinators.

Other crops grown for ensiling on occasions include linseed and field beans. Little information is available on the yield potential or feeding value of these crops when grown for forage.

In Indiana dill is sown, early in spring, directly in the field with a beet or bean drill, in rows about 22 inches apart. The crop is ready to harvest in 90 to 105 days. It is harvested with a grain binder, usually about the middle of July, when the earliest seed has ripened. The herb is allowed to cure in the field for a day or two and then distilled with the equipment used in distilling mint. It takes from 2-1/2 to 3 hours to exhaust the charge. The yield ranges from 1 5 to 50 pounds an acre. Al times a second crop is obtained the same year, but the yield is small and usually unprofitable. There are several varieties of dill, some of which are not suitable for the purpose because they yield less oil or oil of poor quality.
