Nearly 50 improved varieties of barley have been distributed to farmers in the past 10 years. 4 few of them are shown above: 1. Arivat Has a stiff straw, matures early, yields 10 percent more than Vaughn in Arizona; 2. Compana—A high spring type popular in Montana, has test weight and resists loose smut, grasshoppers- 3. Rojo—Outyields other varieties in California by 12 percent, resists scald and net blotch; 4. Mars—Yields well and matures early in Minnesota, resists stem rust and stripe but not scab loose smut, or leaf rust; 5. Tregal— Outyields other kinds in North Dakota, resists loose smut; 6. Velvon 11—Adapted to Intermountain irrigated area, combines well, good for feeding and bedding; 7. Flynn 37—Resists drought, combines well, good for hay in Columbia River Basin; 8. Flynn 1—Popular on the Great Plains, outyields other kinds, resists grasshoppers and greenbugs but is subject to smut; 9. Munsing—Has high test weight and yield on Great Plains, livestock like its straw; 10. Wong—Derived from China and now adapted to Atlantic Coast States, resists mildew, outyields other common types; 11. Reno—A winter barley that withstands the cold, matures early, does well in Kansas and nearby States; 12. Wintex—Grown mostly in Texas and although subject to winterkilling and greenbugs, it outyields other kinds and is good for grazing.

By adapting grain sorghums to machines and machines to sorghums, farmers during the war years greatly increased their acreage of this crop. The crossing of one variety with another to get a desired result is a delicate process as indicated above,by C. L. Lefebvre. Above, is a head of Midland. It is an early variety for Kansas and Nebraska; its stiff, disease-resistant stalks make it good for combining. Below is a field of Martin, named after the Texas farmer who found it; since 1943 it has been the leading variety in the United States. It matures early, dries quickly and thus combines well, and can be grown from South Dakota to southern Texas.

Research on sugarcane has several. objectives: Reduced cost of production through varieties that can be harvested by machine; increased Yields from kinds that resist diseases and insects; and development of kinds that will prevent the spread of noxious weeds. An example of sugarcane that combines well is C. P. 29/320 at Bunkie, La., growing on Yahola soil. Entomologist Ralph Mathes at Houma, La., holds a tall stalk of cane, C. P. 33/409, that resists the sugarcane borer; the other stalk, variety C. P. 29/103, does not. The tall, wide-topped plantsC. P. 34/120, crowd out noxious weeds along ditch banks.

The goal of tobacco research is to develop varieties that resist diseases and are of good quality. The two groups of plants below were inoculated with blue mold; the group at left represents progress in getting resistance to black shank. The resistance comes from the wild species N. debneyi.

More than 700 million acres of western range land are producing less forage than they could; much of the topsoil on them is being lost because of inadequate plant cover. About 4 million acres have been reseeded by modern methods. The picture on this page gives an idea of what can and is being done. Heavy growth of sagebrushusually indicates a good reseeding site; heavy wheat-land plows kill the sagebrush and condition the land for reseeding. Where the soil is rocky, a heave harrow will kill brush and other noxious plants. In scene areas, where there are no rocks or heavy vegetation, disc drillsdo an efficient job without other preparation The picture bellow shows the same area as upper right. By reseeding it to crested wheat-grass, grazing capacity was increased tenfold.
