816. Bezdicek, D.. no date. (Influence of residual soil N on N2 fixation; N2 fixation of chickpeas). unpublished.
High levels of residual soil N decreased N2 fixation. There was a negative correlation between the fraction of plant N derived from N2 fixation and total mineralizable N and KCl extractable N. N2 fixation was reduced by about 2.8 kg/ha for each kg/ha of available soil N. Seed yield response from inoculation ranged from 5-70% and was negatively correlated with available soil N. Residual soil moisture in July was greatestfor large seeded legumes > forage legumes > winter wheat. T: N fixation in chickpeas.

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.

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.

4647. Muehlbauer, F.J., R.W. Short, W.J. Kaiser, D.F. Bezdicek, K.J. Morrison, and D.G. Swan. 1982. Description and culture of chickpeas.. WSU Coop. Ext. Bull. EB 1112.
Describes chickpea culture in the Palouse region; best varieties were UC-5 and Mission; yields range from 2000-3000 lb/ac; inoculation with proper Rhizobium is essential; several herbicides are available; aphids are the only insect pest; several diseases pose problems; a good domestic market is available. T: varieties, yields, herbicides, WA, ID
