Abstract
Seeded and transplanted tomatoes were grown on Brookston clay soil under a number of management practices that were designed to hasten maturity of tomato fruits. The most effective management practice found to hasten maturity was the use of a raised (20-cm-high) bed prepared in the autumn previous to planting. It was also observed that seeded tomatoes required approximately 200 more heat units than transplanted tomatoes to reach the same stage of maturity. A study of various seeding methods indicated that the methods that provided a microenvironment conducive for seed-germination (as with plug-mix) resulted in improved emergence of tomato seedlings.
