2702. Homan, H., L.E. O'Keefe, and R.L. Stoltz. 1984. Aphids on peas and lentils and their control.. ID Agr. Expt. Sta. CIS #748.
Describes life history of pea aphid and cowpea aphid; natural enemies; virus diseases they spread; early planting an advantage; check threshold levels; insecticide controls listed.

4321. McDole, R.E., J.P. Jones, and R.W. Harder. 1978. North Idaho fertilizer guide - Peas and Lentils.. ID Agr. Expt. Sta. CIS #448.
Describes crop needs for P,K,S and micronutients; Starter fertilizer not recommended.

4612. Muehlbauer, F.J.. 1990 Jan.. Pulse crops for drier areas.. presentation at Dryland Extension Agent Training, WSU, Pullman, WA.
For the 14-16" rainfall zone, two pulse crops may be suitable as fallow replacements - the small red lentil and the desi chickpea. The desi chickpea has no insect pest at this time, and does not require seed treatment. It is primarily sold to the export market.

Describes production practices from seedbed preparation to harvest. T: varieties, fertilizer, weed control, insects, disease

5474. Pumphrey, F.V., T.R. Toll and B.L. Klepper. 1985. Edible legume seed yield and water use.. OR Agr. Expt. Sta. Special Report 738, p.44-49.
General growth characteristics, seed yields, and water use of four edible legumes grown at the Pendleton Station are reported. Brewer and Chilean 78 lentils are not as adapted to this climate as are Latah peas. Chickpeas produced yields, seed size, and seed color which would warrant further testing of this species. Production of Diana fababean was not encouraging because of its growth habit and productivity. T: Flowering, maturity and seed yield of legumes, Pendleton, OR. Average weekly water use for Latah peas, Brewer lentil, chickpea, and Diana fababean, Pendleton, OR.

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.

7786. Engel, R., L.E. Welty, R. Lockerman, J. Bergman, G. Kushnak, L. Prestbye, and J. Sims. 1987. Annual legumes and cereal grain rotations in Montana.. Montana AgResearch 4(3):1-4.
Montana researchers examined the performance of several grain legumes (dry pea, chickpea, lentil) and their effect on a subsequent barley crop. Dry pea production was the highest. A subsequent barley crop rsponded to added N fertilizer at three out of six sites. Barley yields following legumes were generally equal to or greater than yields following fallow. The annual legumes contributed to soil N and reduced the fertilizer N needed to reach maximum yield by 40-55 lb N/ac when compared to recrop barley. This translated into savings of $10-14/ac for fertilizer N.

This proceedings covers a wide range of topics relating to food legumes: international programs, genetic resources, cropping systems, management and tillage, harvest and storage, processing and utilization, economics, biotic limitations, IPM, nitrogen fixation, physiology, breeding and biotechnology, and regional reports.

8907. Bremer, E., R.J. Rennie, and D.A. Rennie. 1988. Dinitrogen fixation of lentil, field pea and fababean under dryland conditions.. Can. J. Soil Sci. 68:553-562.
N15 was used to study the N-fixation of several grain legumes in Saskatchewan, with all major soil zones represented. Indigenous rhizobia were incapable of supporting adequate levels of N2 fixation at most sites. Inoculation increased total dry matter, total N, and N2 fixation of all legume cultivars tested. Annual rates of N2 fixation were as high as 75, 105, and 160 kg N/ha for lentil, pea, and fababean, respectively on gray and gray-black soils in one year, but declined by an average of 5.3, 7.6, and 10.5 kg N/ha, repsectively, for every cm reduction in moisture use. Fababean fixed the most N under wetter conditions, while pea and lentil fixed the most under drought stress conditions. The amount of N fixed was not significantly correlated with soil nitrate levels in either year, perhaps due to the overriding effects of moisture. Estimates of the % plant N derived from atmospheric fixation ranged from 30-80%, with fababean generally the highest. The % from atmosphere was negatively correlated to soil nitrate for pea and lentil.
