Average lint yields of eight varieties of Upland cotton ( Gossypium hirsutum L.) planted in 1963 and 1964 in solid and 2×2 skip‐row designs showed a significant yield increase in favor of skip‐row planting. Yields from skip‐row planting were 30 and 61% greater in 1963 and 1964, respectively, than yields from solid planting. Yields are reported on an allotted hectare basis. Comparison of average lint yields of all varieties planted in tests from 1959 to 1964 (no test planted in 1961) showed a significant (P=.01) over‐all increase 42% in favor of skip‐row planting. Differential varietal response to method of planting on lint yields was indicated by significant (P=.01) variety) × method interaction for four varieties studied for 5 years. A significandy (P=.01) greater percentage of total seed cotton was harvested at first picking from solid than from skip‐row planting. Bolls from the skip‐row planting were significantly (P=.01) larger than bolls from solid planting in the 1959–1964 tests. Fiber length increased significantly (P=.05) on varieties grown in the skip‐row design, but mean length, strength, and fineness were unaffected by method of planting.
