Abstract

Among the five varieties planted after June 1, S-100 had a slight advan:tage over Ralsoy in that it matured a few days earlier and yielded a little more seed.Planted prior to June 1, Ralsoy had a slight advantage over S-100.From late planting, July 10, Dunfield matured earlier than any of the other varieties but it yielded less seed.Strain S-100 yielded the highest from plantings after June 1, and matured only twelve days later than Dunfield when planted July 10.Soybean harvest can be hastened as a means of making way for small grain on the soybean field by planting the early maturing varieties early.Both the use of an early maturing variety and early planting are essential to early maturity.While this practice may cause considerable reduction in the soybean yield and quality, it is still considered sound from the standpoint of total production by the rotation.If planting is delayed because of wet weather or until after the harvest of small grains, the use of late maturing varieties is recommended, as early varieties will give lower yield of seed without much gain in earliness of maturity.The date of planting which produced the highest seed yields also resolted in seed with the highest oil content.In general, the percentage of protein varied inversely with percentage of oil.The iodine number of the oils tended to increase with lateness of planting.
