The influence of Trichoderma fungi on growth, yield and nutrient status of food crops has been widely studied.However, a lack of knowledge still exists on the effect of agricultural soils with different geological nature, landuse and management on Trichoderma-plant interaction. This study aims to evaluate the influence of three soiltypes, with different physicochemical properties and under fertilization by NPK-based nutrient solutions, on theefficacy of two T. harzianum (T22 and M10) strains on the growth, nutrient uptake and glucosinolate concentrationin Brassica rapa subsp. sylvestris cv. esculenta. Overall data showed that the biofertilization byTrichoderma strains is very effective to enhance the fertility and productivity of the nutrient-poor soils even inthe absence of fertilization by NPK-nutrient solutions, as well as to stimulate the production of glucosinolates byfoliar biomass of B. rapa, although this effect was strongly dependent on the soil type.

Abstract
The influence of Trichoderma fungi on growth, yield and nutrient status of food crops has been widely studied.However, a lack of knowledge still exists on the effect of agricultural soils with different geological nature, landuse and management on Trichoderma-plant interaction. This study aims to evaluate the influence of three soiltypes, with different physicochemical properties and under fertilization by NPK-based nutrient solutions, on theefficacy of two T. harzianum (T22 and M10) strains on the growth, nutrient uptake and glucosinolate concentrationin Brassica rapa subsp. sylvestris cv. esculenta. Overall data showed that the biofertilization byTrichoderma strains is very effective to enhance the fertility and productivity of the nutrient-poor soils even inthe absence of fertilization by NPK-nutrient solutions, as well as to stimulate the production of glucosinolates byfoliar biomass of B. rapa, although this effect was strongly dependent on the soil type.| File | Dimensione | Formato | |
