Two short staple variety trials were held in Graham county, one toward the west end of the valley (Eden), and one in the center of the valley (Thatcher), both with 15 varieties. Delta Pine 90 was the highest yielding variety at both locations, with yields of 1,386 pounds of lint per acre at Thatcher and 1,123 pounds at Eden. Two new varieties, Northrup King 111 and BR 110, show some promise in the area, with yields close to that of Delta Pine 90. Lint quality and grade are listed for each variety.

Eleven varieties of short staple cotton, containing four varieties of Acala 1517 (including two new releases from New Mexico State University) were grown near the town of Cochise, which is at an elevation of 4,180 feet and has an average growing season of 232 days. Northrup King's KC 380 (the same as the experimental variety 2019) was the high yielder for the second year in a row, with 954.6 pounds of lint per acre. One of the new Acala' s, 1517-77BR was second in yield, with 936.5 pounds per acre. With the current premium structure, 1517-77BR would produce about $50 more gross farm income per acre than KC 380.

The check variety, Delta Pine 90, produced more than any of the new varieties in this unreplicated strip test. However, three new varieties produced yields within 10 % of the Delta Pine 90 yields; they were BR 110, Northrup King 111 and Germains GC 365.
