A greenhouse tomato test was performed at the Yale School
of Forestry and Environmental Studies, New Haven, CT to evaluate the effects
of ROOTS®, on the production of tomato fresh weight.
Seeds of tomato var. Burpee Big Boy from Agway Seeds, Syracuse,
NY were sown on April 10, 1990 in trays containing vermiculite. When seedlings
were germinated and reached 4—5 cm height (May 4, 1990) they were transplanted
to two—liter pots filled with a mix of Agway potting soil and vermiculite
(1:1 in volume) one plant per one. When the plants started to grow, the
stems were supported by bamboo sticks.
Sixty seedlings were taken as a control, and sixty were
treated four times (100 ml each per pot ) with a 1% solution
of
ROOTS® on May 12, May 26, June 30, and July 14, 1990.
Fertilizer was applied during the May 26, and July 14 treatments
(Miracle—Gro 15—30—15, 1 g/liter)
Tomato harvest started 8/7/90 and continued up to 9/26/90
when all fruits were harvested and then the whole plants were harvested
and weights were determined. Analysis of variance was made with Statview
II.
Significant differences (P<0.05) were observed between
the tomato production of the group treated with ROOTS® and the non-
treated control. For the ROOTS® treated plants results were 28% higher
than the control.
