Abstract
▄ Dickey : Generally, no-till did well. The worst situations were in conventionally tilled fields. Of 10 side-by-side tillage system comparisons, only one site had a higher yield with conventional tillage, by two bushels on soybeans. Yields from seed corn variety trials on dryland were higher with no-till than with conventional (chisel plow) tillage. Results from farmers were mixed. Some thought no-till had higher yields while others indicated that yields from no-till were less than expected. Overall, no-till showed a slight advantage in 1988, partly because Nebraska farmers are used to working with less rainfall than producers in other states. ▄ Eckert : Most properly executed conservation tillage systems performed in 1988 as they normally would, despite the extremely dry weather. On well-drained soils, no-till produced higher yields than moldboard plowing, as is the normal case, even though early growth was much slower. On more poorly drained soils, no-till yields were comparable to conventional tillage yields if adequate residue was present, proper rotation was practiced, and the field had a history of improved drainage to promote acceptable soil structure for root development. ▄ Larson : Given the high variability in corn and soybean …
