second cut, each seedbed was again sprayed with 4 mL/
36 cm2 of their own solutions, i.e., water, standard fertilizer
solution and the experimental solution. After the
third and fourth cut, no additional solutions (fertilizer
and experimental) were incorporated in order to check
the possible residual effect of the extract (experimental
solution). After the first, second and third cut each seedbed
was again sprayed with 0.5 mL/cm2 of water.
