Plats A-II-1 and A-II-2 were planted on very heavy, low ground 

 which was difficult to get into perfect condition for seeding, with the 

 result that a poor stand was secured. These plats were therefore 

 plowed up in the fall of 1911. Of the grasses in the combinations, 

 Bromus inermis, orchard grass, and Italian rye-grass have made the 

 best stand, Bromus inermis doing especially well. 



DISTANCE OF PLANTING AND THINNING SUGAR BEETS. 



Special work with sugar beets has l)een carried on in cooperation 

 with the Office of Cotton and Truck Disease and Sugar-Plant Investi- 

 gations. This included tests of time of irrigation and distance of 

 planting and thinning. In the distance of planting and thinning 

 experiment a series of 45 plats was used in 1912. Fifteen plats were 

 planted in rows 18 inches apart, 15 plats in rows 20 inches apart, and 

 15 plats in rows 24 inches apart. These were thinned to 6, 9, 12, 15, 

 and 18 inches apart in the rows. All plats were run in triplicate. 

 The average yield from the entire series was 15.5 tons per acre. The 

 results obtained indicate that, regardless of the distance of thinning, 

 the 18-inch rows will give the best yields. The best combination 

 of thinning and planting was the 18-inch rows thinned to 12 inches. 

 The three plats planted in this way produced an average yield of 

 17.8 tons per acre, the highest yield obtained. There was but slight 

 variation in the sugar content of the beets grown in the different 

 plats, the average being 18.7 per cent. 



In the irrigation test w^ith beets it was impossible to follow the 

 plan as outlined, because of the unusually copious rains during the 

 season; therefore, the differences in the yields obtained in 1912 were 

 not significant.
