Abstract
Abstract ‘Jubilee’ sweet corn (Zea mays L.) was grown under conventional and strip tillage in 1982 and under conventional tillage, strip tillage, and no-till culture in 1983. Stand establishment was decreased by strip tillage in 1982, but was lower only in the no-till treatment in 1983. Midseason plant height in strip tillage was slightly less than in conventional tillage both years, whereas the no-till plants were much shorter than in other treatments the second year. Yields of husked ears from strip tillage were 7% and 16% lower than from conventional tillage in 1982 and 1983, respectively. In 1983, yield from the no-till treatment was 31% lower than from conventional tillage. The percentage of kernel moisture always was higher from plants in strip tillage and no-till, indicating these treatments had ears that were more immature at time of harvest than in conventional tillage. Average daily soil temperatures at the 5 cm depth for the first 30 days after planting in 1983 were highest for conventional tillage, followed by strip tillage and no-till.
