Effects of Legumes in Different Cropping Systems on Yield of Corn
1952
Reynolds, E. B. | Norris, M. J.
There were no significant differences in the yields of corn in 1950 at College Station where corn followed cotton which was preceded immediately by hairy vetch, Willamette vetch, Austrian Winter peas, Dixie Wonder peas, and Singletary peas plowed under for soil improvement. The application of 60 pounds of nitrogen per acre to the corn, however, produced a highly significant increase in the yield of corn. Of the four legumes and six cropping systems included in the work at Denton, only Hubam and Madrid sweetclovers produced significant increases in the yield of corn in 1950. Corn after Hubam sweetclover for green manure produced only 2 bushels per acre more than corn following Hubam sweetclover for seed. Austrian Winter peas and Dixie Wonder peas did not increase the yield of corn, probably because they made very little growth.
