“…It is well known that the unused N by plants ends up polluting the environment, and so the adjustment of chemical N fertilizer dosages or even the replacement with biofertilizers are needed goals. Either way, there is still a lack of knowledge upon the use of beneficial organisms such as Trichoderma on wheat crops and their effects on fertilization (Meena et al, 2016;Mahato et al, 2018).…”

Effect of Inorganic N Top Dressing and Trichoderma harzianum Seed-Inoculation on Crop Yield and the Shaping of Root Microbial Communities of Wheat Plants Cultivated Under High Basal N Fertilization

et al. 2020

Wheat crop production needs nitrogen (N) for ensuring yield and quality. High doses of inorganic N fertilizer are applied to soil before sowing (basal dressing), with additional doses supplied along the cultivation (top dressing). Here, a long-term wheat field trial (12 plots), including four conditions (control, N top dressing, Trichoderma harzianum T34 seed-inoculation, and top dressing plus T34) in triplicate, was performed to assess, under high basal N fertilization, the influence of these treatments on crop yield and root microbial community shaping. Crop yield was not affected by top dressing and T. harzianum T34, but top dressing significantly increased grain protein and gluten contents. Twenty-seven-week old wheat plants were collected at 12 days after top dressing application and sampled as bulk soil, rhizosphere and root endosphere compartments in order to analyze their bacterial and fungal assemblies by 16S rDNA and ITS2 high-throughput sequencing, respectively. Significant differences for bacterial and fungal richness and diversity were detected among the three compartments with a microbial decline from bulk soil to root endosphere. The most abundant wheat root phyla were Proteobacteria and Actinobacteria for bacteria, and Ascomycota and Basidiomycota for fungi. An enrichment of genera commonly associated with soils subjected to chemical N fertilization was observed: Kaistobacter, Mortierella, and Solicoccozyma in bulk soil, Olpidium in rhizosphere, and Janthinobacterium and Pedobacter in root endosphere. Taxa whose abundance significantly differed among conditions within each compartment were identified. Results show that: (i) single or strain T34-combined application of N top dressing affected to a greater extent the bulk soil bacterial levels than the use of T34 alone; (ii) when N top dressing and T34 were applied in combination, the N fertilizer played a more decisive role in the bacterial microbiome

“…A Neubauer haemocytometer was used to adjust the T. harzianum spore concentration to 2 × 10 5 spore/ml (working solution). The soil with one-month-old tomato plants was drenched with 100 ml of working solution (Mahato et al, 2018). After 24 hours, the same amount of 2 × 10 5 spore/ml pathogen suspension was added to the soil per pot.…”

Fusarium wilt of tomato plants caused by Fusarium oxysporum Schlecht. emend. Snyder & Hansen and Fusarium solani (Mart.) Sacc. are serious problem limiting tomato production worldwide. Biological control has emerged as one of the most promising alternatives to chemical fungicides. The biological control capability of a T. harzianum isolate against F. solani and F. oxysporum has been investigated. It inhibited colony growth of two Fusarium species by more than 80 % in dual culture tests. Results of greenhouse experiments revealed that disease severity in the tomato plants co-inoculated with T. harzianum was significantly lower than plants only infected with the Fusarium pathogens. Tomato plants inoculated with the antagonistic T. harzianum isolate, showed enhanced peroxidase and polyphenol oxidase activities in greenhouse experiments and increased resistance to F. solani and F. oxysporum. The T. harzianum isolate indirectly affected the Fusarium pathogens by enhancing plant defence.

In the world, the traditional agricultural practices are getting affected by various problems such as disease, pest, drought, decreased soil fertility due to use of hazardous chemical pesticides, pollution and global warming. As a result, there is a need for some eco-friendly bio-control agents that help in resolving the previous mentioned problems. The various types of biological control agents such as bacteria and fungi are involved in bio-control activity. Among them, fungal genus Trichoderma plays a major role in controlling the plant diseases. Species of Trichoderma are diverse fungal microbial community known and explored worldwide for their versatilities as biocontrol and growth promoting agents. These fungi reproduce asexually by production of conidia and chlamydospores and in wild habitats by ascospores. Trichoderma species are efficient mycoparasites and prolific producers of secondary metabolites, some of which have clinical importance. However, the ecological or biological significance of this metabolite diversity is sorely lagging behind the chemical significance. Several Trichoderma spp. positively affect plants by stimulating plant growth, and protecting plants from fungal and bacterial pathogens. They are used in biological plant protection as bio-fungicides as well as in bioremediation. A large number of research groups are working on various aspects of Trichoderma viz., diversity, ecology and their applications. The capacity of Trichoderma fungi to produce lytic enzymes is used in animal feed, and wine making and brewery industries. Trichoderma spp. are the most successful bio-control agents as more than 60% of the registered bio-fungicides used in today’s agriculture belongs to Trichoderma -based formulation. The increase in incidence and severity of diseases and emergence of new diseases causes the significant yield losses of different crops in Nepal. But the research and studies on plant diseases are limited. Int. J. Appl. Sci. Biotechnol. Vol 7(3): 309-316
