4536. Moodie, C.D. and S.C. Vandecaveye. 1944. Yield and nitrogen content of chickpeas, Cicer arietinum, as affected by seed inoculation.. Soil Sci. Soc. Am. Proc., 8:229-233.
A study of 2 yrs duration was made of the effect of inoculation upon the growth and nitrogen content of chickpeas. It was shown that chickpeas are readily inoculated, nodulate very proficiently by a suitable species of Rhizobium, and do not belong in the R. leguminosarium cross inoculation group. Chickpeas appeared to be more efficient in fixing atmospheric nitrogen than are field peas, and since they are grown as an intertilled crop some of the aspects of summer-fallowing are retained. The data obtained under the conditions of the experiments indicate that in so far as soil nitrogen economy is concerned the inclusion of chickpeas in the agricultural practice in the semi-arid area in eastern Washington where the annual rainfall is 18 inches or more offers considerable promise as an improvement on summer-fallow when grown in rotation with wheat. T: Yields and nitrogen content of chickpeas in 1941. Height, yield and nitrogen content of chickpeas in sand culture. Grain yields and nitrogen content of green and mature tissues of chickpeas in 1942.

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.
