1918-1924, 722 acres in peas; often replace summer fallow; peas improve soil condition; yields 10-18 bu/ac and 18-23 bu/ac; variety information, date of planting, planting rate, depth of seeding; harrow after emergence; inoculation response noted; used as a nurse crop for grasses and legumes; WW yields same after peas vs. SF; noted rotation effect; pea weevil - fumigate with carbon bisulphide for seed trt.; also heat seed to 125-140 degrees F; pea aphid a problem.

6518. Smith, S.C., D.F. Bezdicek, R.F. Turco, and H.H. Cheng. 1987. Seasonal N2 fixation by cool-season pulses based on several 15N methods.. Plant Soil 97:3-13.
Used 15N to determine N2 fixation by fababean, lentil, Alaska pea, Austrian winter pea, blue lupin, and chickpea. Mean seasonal N2 fixation by fababean, lentil, and AWP was near 80 kg N/ha, pea and lupin near 60 kg N/ha, and chickpea less than 10 kg N/ha. The net effects on the soil N pool ranged from 70 kg N/ha input by lentil to a removal of 48 kg N/ha by chickpea. Pulse crops often remove more N in the seed than they fix, leaving a deficit for the next crop. T: legume DM, total plant N, seed yield, seed N; N fixation values by different methods.
