Project Information


Note to readers, attached is the complete final report for FNE94-074.

Mulching tomatoes with no trellis gave the best harvest during the month of September. Also, this system had the highest overall yield for the season.

The foliage on the tomato plants sprayed with copper were significantly better throughout and especially in mid-late September when the other two systems had begun to defoliate quite rapidly.

Through August, trellised plants produced about 38% more fruit. By the end of the season, total yield had dropped to 10% less than non-trellised plants.

Mulching plants were significantly better at first in producing more fruit. However, the percentage of gain dropped steadily from 60 to 30 to 22 to 16 to 6 to 2 percent better as the season progressed.
