3507. Kapoor, P. and P.S. Ramakrishnan. 1975. Studies on crop-legume behavior in pure and mixed stands.. Agro-ecosystems, 2:61-74.
In mixtures, an increase in the density of Trigonella polycerata resulted in an increased dry weight yield of the crop and only at very high densities of Trigonella was there an adverse effect of the weed on the crop. It is suggested that stimulation of the crop is related to nitrogen enrichment of the soil due to the nodular bacteria in the root of the weed.

4713. Murray, G.A. and J.B. Swenson. 1984. Intercropping Austrian winter peas and winter cereals for seed.. ID Agr. Expt. Sta. CIS #749.
Peas seeded at 25, 50 and 75% of mixture with winter wheat or barley; both crops harvested on same day; 25% cereal, 75% pea was best mix; less lodging, less disease, 27% yield increase; cereal yields very low; apperently no N advantage to cereal from the pea; less lodging with winter wheat compared to winter barley; better maturity match with barley; LER over 130 with WW(25%) + WP(75%). T: yield, seed size.

10756. Laird, E.. 1988. Grain legume mixtures and intercropping.. Proc. Crop diversification in sustainable agriculture systems, Univ. Sask., Saskatoon, p. 20-25.
The experience of several Saskatchewan farmers with intercropping is discussed. Some examples are durum wheat and flax, spring wheat and fall rye, rye and oats, rye and flax, peas and oats, mustard and peas, clover and oats. With wheat and rye, seeded together in the spring, the wheat is harvested the first year and the rye the next year. The rye discourages broadleaf weeds.
