| Zusammenfassung |
| Soil salinity is a major soil degradation threat, especially for arid coastal environments where
it hinders agricultural production and soil health. Protected horticultural crops in the
Mediterranean region, typically under deficit irrigation and intensive cultivation practices,
have to cope with increasing irrigation water and soil salinization. This study quantifies the
beneficial effects of the Trichoderma harzianum (TH) on the sustainable production of
Solanum lycopersicum (tomato), a major greenhouse crop of the RECARE project Case
Study in Greece, the semi-arid coastal Timpaki basin in south-central Crete. 20 vigorous
20-day-old Solanum lycopersicum L. cv Elpida seedlings are treated with TH fungi (T) or
without (N) and transplanted into 35 L pots under greenhouse conditions. Use of
local planting soil with initial Electrical Conductivity (ECe) 1.8 dS m−1 and local
cultivation practices aim to simulate the prevailing conditions at the Case Study. In
order to simulate seawater intrusion affected irrigation, plants are drip irrigated with
two NaCl treatments: slightly (S) saline (ECw = 1.1 dS m−1) and moderately (M)
saline water (ECw = 3.5 dS m−1), resulting to very high and excessively high ECe,
respectively. Preliminary analysis of below and aboveground biomass, soil quality, salinity,
and biodiversity indicators, suggest that TH pre-inoculation of tomato plants at
both S and M treatments improve yield, soil biodiversity and overall soil health. |
