| Summary: | The intercropping of corn with legumes is an alternative cropping strategy to corn monocropping which may help reduce inputs into the production of silage for livestock feed. The reduction of inputs will decrease costs to producers and potential damage to the environment. Two experiments were carried out at each of two sites in 1993 and 1994. The first experiment investigated the effects on silage yield and weed control of seeding soybean or lupin alone or in combination with one of three forages (annual ryegrass, Lolium multiflorum Lam.; perennial ryegrass, Lolium perenne L.; and red clover, Trifolium pratense L.). The second experiment examined the effects on silage yield and weed control of seeding date (simultaneous with corn or three weeks later) and number of rows of large-seeded legumes (one or two) seeded between the corn rows. For both experiments intercropped plots received 90 kg ha$ sp{-1}$ less nitrogen fertilizer than monocropped plots (which received 180 kg ha$ sp{-1})$. (Abstract shortened by UMI.)
