ABSTRACT:
The aim of
this study was to evaluate the effect of heated soil on the population of
bacteria, fungi and nematodes inhabiting the soil of tomato cultivar “Tamaris” growing in peat and coconut substrates. In
addition, these media were tested in two different containers: cylinders and
slabs. The total number of bacteria and fungi was significantly higher in the peat substrate than
in the coconut substrate. A
much higher number of beneficial bacteria producing spores were noted in the coconut soil. The total number of
bacteria and fungi was modified by the heating levels. In all the experimental
treatments, most of the identified individuals belonged to the group of
nematodes that feed on bacteria and it was the most diverse group of species. The
highest total number of nematodes was recorded for the second heating level,
with the exception of cultivation carried out in peat slabs, where the most of
nematodes were found at the control level. The highest first crop was produced
by plants growing on the peat slabs supplied with the highest soil temperature. Tomato roots of all the control treatments showed the highest root morphological parameters.
