Tested tangier flatpea, indianhead lentil, fababean, field pea, and Austrain winter pea at several locations. Data suggest that annual legume green manures contributed about 40 lb N/ac, and increased wheat yields more than the addition of 54 lb N fertilizer on wheat stubble. Moisture greatly affected yield after legumes. Choice of annual legume depends on relative seed cost. Suggest indianhead lentil as most promising species. The value of the N it fixes comes close to the seed cost. Three management systems are proposed.
7662. Wright, A.T. and E. Coxworth. 1987. Benefits from pulses in the cropping systems of northern Canada. p. 108. IN: J.F. Power (ed.). The role of legumes in conservation tillage systems..
Investigated yield and N response in barley and wheat, 1 and 2 years after pulse crops of fababean, pea, and lentil. Overall yields were higher on fababean and field pea residues than lentils. Soil tests could not attribute yield differences among crop residues to differences in soil N levels at time of seeding. Nitrogen fertilizer equivalents for barley were 105, 85, and 50 lb N/ac for fababean, peas, and lentils. Legume residues influenced barley grain quality. In the second year following pulses, the dry matter yield, grain yield, and N uptake of wheat was 15% higher than in the continuous cereal sequence. Analysis of 3 completed rotation cycles showed that cropping sequences that included pulses were considerably more productive than the continuous cereal sequence in terms of net energy production and economic gross margin to cash costs. Field peas were the most effective first-year crop in terms of net energy production.

Historically, forage legume improvement has received minimal attention relative to other major crops. This has limited the availability of well-adapted and studied cultivars for dryland environments. Adaptation of the Australian ley farming system to Montana is showing promise with annual medics. Also, cereal-pulse rotations are being successfully used in more areas. Over twenty potential fallow-replacing cover crops are being evaluated across Montana. The Indianhead lentil, developed in Saskatchewan as a cover crop, is also showing promise.
