Mghest yields of oats were obtained from the ()0-Ib. seeding made Octoljer 1, 

 lbs. October 15, 90 lbs. November 1, and IL'U lbs. per acre November 15. 

 Che seeding made November 15 showed tlie largest anunnit of winterkilling 



id the one made October 15 the least damage from tliis cause. 



The agricultural couditions and work with held crops of the liuatley 

 rRechimation Project E.\periineiit Farm in 1918, D. Hansen {U. S. Dept. 

 Agr., Dept. Circ. S6 (1920), pp. 1-Jf, 6-18, figs. 3).— The crop conditions of the 

 project are described, the acreage, yields, and farm vahiei? of crops produced 

 there, and the number of live stock are given in tables, the lines of work of 

 the experiment farm, located near Osborn, Mont., are briefly noted, and the 

 results of ticld-crop experiments in IDIS are reported in continuation of earlier 

 work (E. S. U., 39, p. 834). 



The plans of the rotation experiments in progress are outlined, and tlie 

 yields of the various crops in the dillerent rotations are tabuhited. The results 

 of these tests from 1912-1918, inclusive, are regarded as indicating that alfalfa 

 seeded in the fall in oat stubble gives better yields than when seeded the 

 following spring, and that sugar beets make the greatest yields in a rotation 

 in which one of the crops is manured or when following a cultivated crop. 

 Potatoes and oats produced best when grown in a rotation including alfalfa 

 or a manured crop. The best average yield of wheat was obtained in a two- 

 year rotation with sugar beets. For the past six years flax in rotation gave 

 more than double the yield of flax under continuous cropping. 



In a test of sunflowers for silage in 1918 the highest yield, 37.62 tons per 

 acre, was obtained from rows 20 in. apart with plants 3 in. apart in the row. 

 Of three varieties of corn Northwestern Dent gave the best yield, a total of 

 10,439 lbs. of corn and stover per acre. 



Clover-seed production was found profitable only when the first crop was 

 left for seed. Of five varieties of barley in 1918 on land broken up from the 

 native sod the year before Trebi ranked first in yield with 70.5 bu. per acre, 

 being followed by White Smyrna and Chevalier with 62 and 61. 5 bu., re- 

 spectively. 



Brief notes on winter injury of apples, plums, and cherries are also given. 



The agricultural conditions and work with field crops in 1918 of the 

 Newlands Reclamation Project Experiment Farm, F. B. Headley (U. S. Dept. 

 Agr., Dept. Circ. 80 (1920), pp. 1-5, 8-lJi, fig. 1). — In a discussion of the agri- 

 cultural conditions of Newlands (formerly the Truckee-Carson) Reclamation 

 Project the average values of farm products per acre and the acreage and 

 production of leading crops for 1912-1918, inclusive, and the acreage, yields, and 

 farm values of the 1918 crops and the number and value of the live stock in 

 1918 are tabulated. The character of the work in progress at the project ex- 

 periment farm near Fallon, Nev., is described, and the results of varietal and 

 cultural tests are reported in continuation of previous work. (E. S. R., 40, 

 i). 31. 



According to the ri'sults of varietal tests in 1918 and in preceding years, 

 Coast barley, Australian White Flint, Wimples Yellow Dent, and Minnesota 

 No. 13 corn, and Little Club wheat seemed best adapted to the conditions of 

 the project. In 1918, Blue Visitor, among eight varieties of potatoes, raidied 

 first in yield. In time of planting tests in 1918, the highest average yield was 

 secured from planting April 23 as compared with planting April 17 and 30 

 and May 7, 14, and 21. Selected seed potatoes yielded nearly 50 per cent more 

 than regular stock. Eelworm-infested seed tubers, as a whole, did not germinate 

 or yield so well as noninfested seed. Flax, buckwheat, and Sudan grass gave 

 promising yields in 1918.
