The Effect of Inoculation upon Yields of Soybeans on Treated and Untreated Soils1

Abstract

Abstract

This experiment was designed to evaluate the importance of inoculation of soybeans when grown on land where well-nodulated soybeans had been grown previously. The effect of soil conditions, and of time interval following previous inoculation, upon response of soybeans to inoculation was observed.

Neither soil treatment or interval of time since the host plant had been grown had any influence upon crop response to inoculation. Even on plots which had not grown soybeans since 1939, inoculation did not increase soybean yields. Although inoculated soybeans gave smaller yields than did the uninoculated in many cases, no significance was attached to this observation. Fields having a total nitrogen content of less than 3,000 pounds per acre gave a higher proportion of gains to losses than those containing more than this amount. Yields of both inoculated and uninoculated crops were greater on soils which had been treated with limestone, phosphate, and potash than on untreated check plots. It is concluded that inoculation should be practiced as an inexpensive insurance policy.
