ROWING of sugar beet seed by the overwintering method ( 2 ) 3 G has come into widespread use in the United States during the past 12 years. The development of sugar beet seed production by this method in Oregon, leading to the studies reported in this paper, has taken place in the past 5 years (IO). From results with the sugar beet seed crop in various areas it appears that soils of good tilth and more than average fertility are desirable for growing the crop. In addition to the use of manure, nitrogenous fertilizers applied as side-dressings to the growing crop are commonly used (3, 5 ) . It has been shown that the nitrogen supply available to the plant during the fruiting period governs, to a large extent, the utilization by the plant of stored carbohydrate reserves in the sugar beet root. If nitrogen becomes a limiting factor during this period, utilization of carbohydrate root reserves stops and the maturing of the seed crop may be seriously interfered with ( 5 ) . In 1914, Reimer (6), in a preliminary report, called attention to serious sulfur deficiencies in soils in southern Oregon and, in 1919, with Tarter (7) , gave a full account of the results from sulfur application. Since that date extensive work carried on by the Oregon Experiment Station has demonstrated the value of sulfur as a fertilizer on many crops in western Oregon (I, 4, 9). The preliminary studies reported in this paper deal with both nitrogen and sulfur deficiencies in relation to sugar beet seed, production, and the further relationship of sulfur deficiency to nitrogen utilization.
