Soybean varieties are different in tolerance to lime-induced chlorosis. Field trials were conducted to evaluate variety performance on soils where chlorosis in soybeans was a known problem. Thirty-six varieties out of 177 were identified as tolerant to soil conditions that cause chlorosis. Eleven varieties of these 36 were found to have the most consistent yield performance on high pH soils. Tolerant varieties must be planted at adequate densities for best performance. A seeding rate of 13.5 seeds per foot of row, the highest seeding rate employed, did not appear to maximize yield on soils where chlorosis was severe. On some …
Yields In Different Cropping Systems And Fertilizer Tests Under Stubble Mulching And Plowing In Eastern Nebraska, F. L. Duley
Yields In Different Cropping Systems And Fertilizer Tests Under Stubble Mulching And Plowing In Eastern Nebraska, F. L. Duley
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
The material in this report will be confined chiefly to studies on crop production with stubble-mulching compared with plowing. Major cash crops have been studied in different rotations including legumes and non-legume crops. In all tests, plowing has been compared with subsurface tillage. Different types of equipment have been devised and tested for the various operations during the course of these studies.

Fusarium Blight Of The Soy Bean And The Relation Of Various Factors To Infection, Richard O. Cromwell
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
An investigation was outlined (1) to determine the parasitism of Fusarium on soy bean, (2) to establish its relationship to Fusaria of the section Elegans in so far as a comparison of the cultural characters permitted, and (3) by means of cross- inoculations and field studies to determine the relationship of this disease of soy beans to the wilt disease of cowpeas (Vigna sinensis Hassk.) caused by Fusarium tracheiphilum Smith. The results of these investigations up to the close of the summer of 1916 have been reported. The studies were continued at the North Carolina Experiment Station until the …
