چکیده
Introduction Interest in organic production methods for vegetables continues to increase. Production practices for organic field production of vegetables have a long history, but practices to grow organic vegetable transplants in a spring greenhouse are poorly known. Organic fertilizers and composts are available but the efficacy and rates for use have not been evaluated. Experiments in the summer of 2003 were completed to learn more about the use of two organic fertilizers (fish emulsion 5-1-1 and Omega 6-6-6) and three composts (derived from horse manure, cow manure and worm castings) for the production of vegetable transplants.
