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.

Small red lentils may provide a viable cash crop substitute for summer fallow in the 14-18 inch rainfall zone. Yields at Davenport were 1,202 lb/acre an 1988 (a drought year). Red lentils consume little water and would not interfere with subsequent winter wheat seeding. They require no nitrogen fertilizer, can be grown with conservation tillage, and reduce disease incidence in wheat.

Lentils may be adaptable to a wider range of uses in crop rotations as a result of breeding work by the USDA-ARS at Pullman, WA. Winter hardy lentils are being selected that could fit nicely into reduced tillage systems. Yield potential should be higher with a fall planting, but current winter lentil yields are similar to spring seedings. Advantages include avoidance of spring soil compaction, efficient use of moisture, and planting into standing stubble. A small red lentil is being developed for use in areas with 14-18" precipitation as a replacement for summer fallow. Planting winter wheat after lentils can reduce pythium root rot, Rhizoctonia root rot, Cephalosporium stripe, and take-all diseases.
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.
