What is Intercropping of Corn with Soybean, Lupin and Forages: Silage Yield and Quality about?

Intercropping of corn with legumes is an alternative to corn monocropping and has a number of advantages, for example, lower levels of inputs, lower cost of production and better silage quality than monocrop systems. An experiment was carried out at two sites in 1993 and 1994 to investigate the effects of seeding soybean or lupin alone or in combination with one of three forages (annual ryegrass, __Lolium multiflorum__ Lam.; perennial ryegrass, __Lolium perenne__ L.; red clover, __Trifolium pratense__ L.) on silage yield and quality. The intercrop plots received 90 kg ha^−1^ less nitrogen fertilizer than monocrop plots, which received 180 kg ha^−1^. Corn biomass yield had a variable response to the treatments, but showed no change at most site‐years. Soybean and lupin biomass yields were decreased by intercropping (80–98 % for soybean, and 94–100 % for lupin). However, when corn growth was limited due to poor establishment at one site in 1994, soybean was able to grow well and produce yields similar to those of monocropped soybean. The three underseeded forages did not grow well during the period examined (up to silage harvest) and had no effect on the yield of any crop. Total sila
