Effectiveness of Trichoderma harzianum in soil and yield conservation of tomato crops under saline irrigation

摘要: Abstract Protected horticultural crops in the Mediterranean region are typically under deficit irrigation and intensive cultivation practices must cope with poor soil quality due to salinization. The effects of variable water use beneficial fungus Trichoderma harzianum on evolution salinization yield during a single cropping season examined at small-scale Solanum lycopersicum L. cv Elpida greenhouse experiment. experiment simulates typical coastal conditions RECARE Project Case Study Greece (Timpaki basin Crete). Local NaCl-free but highly calcareous planting as well local were used replicate prevailing Study. Tomato plants drip irrigated NaCl solutions low (L) (ECw = 1.1 dS m−1) high (H) (ECw = 3.5 dS m−1) concentration emulate “good quality” “marginal water, respectively. T. (T) was selectively applied resulting total 2 treatments colonized (LT, HT) two not (N) (LN, HN). For salinity HN HT, sodium adsorption ratio (SAR) values settled 22.2 13.4, respectively, showing that reduced effect significantly. Monitoring nutrients showed significant decrease P-Olsen non-T. versus no change treatments. Final marketable tomato for treatment compared LN by 28% 42%, having effect. Fruit characteristics overall less sensitive higher than timing harvest. We conclude that, irrigation, an early harvest termination has impact while obviating pressure resources conserving agricultural input.
