“…They concluded that SRI field management creates a more congenial environment for Trichoderma to contribute to plants’ growth and development traits, to more supportive soil conditions and nutrient uptake, and ultimately to the rice plants’ productivity, whereas conventional cultivation practices were seen to have detrimental effects. Doni et al (2018) have shown further that farmers can produce and inoculate their SRI seedlings with Trichoderma on a cost-effective basis.…”

Many benefits of Trichoderma inoculation for improving crop production have been documented, including growth and yield enhancement and the alleviation of biotic and abiotic stresses. However, because rice is usually cultivated under continuous flooding that creates anaerobic soil conditions, this limits the benefits of these beneficial fungi. Cultivating rice with the methods of the System of Rice Intensification (SRI) provides rice plants with a more favorable environment for their colonization by beneficial microbes in the soil because the soil is more aerobic under SRI management and contains more organic matter. This study evaluated the effects of Trichoderma inoculation of rice plants under SRI management compared with transplanted and flooded rice plants, considering also the effects of different means of fertilization and different varieties in rice. Experiments were conducted in 2015 and 2016 under the tropical climate of Nepal’s western terai (plains) during both the rainy season (July to November) and the dry season (March to July). The results indicated significantly better performance (P = 0.01) associated with Trichoderma inoculation for both seasons and for both systems of crop management in terms of grain yield and other growth-contributing factors, compared to non-inoculated rice cropping. Relatively higher effects on grain yield were recorded also with organic compared to inorganic fertilization; for unimproved (heirloom) varieties compared with improved varieties; and from SRI vs. conventional flooded crop management. The yield increase with Trichoderma treatments across all trials was 31% higher than in untreated plots (4.9 vs 4.5 mt ha−1). With Trichoderma treatment, yields compared with non-treated plots were 24% higher with organic SRI (6.38 vs 5.13 mt ha−1) and 52% higher with non-organic SRI (6.38 vs 3.53 mt ha−1). With regard to varietal differences, under SRI management Trichoderma inoculation of the improved variety Sukhadhan-3 led to 26% higher yield (6.35 vs 5.04 mt ha−1), and with the heirloom variety Tilkidhan, yield was 41% higher (6.29 vs 4.45 mt ha−1). Economic analysis indicated that expanding the organic cultivation of local landraces under SRI management should be profitable for farmers where such rice has a good market price due to its premium quality and high demand and when SRI enhances yield. These varieties’ present low yields can be significantly increased by integrating Trichoderma bio-inoculation with SRI cultural methods. Other recent research has shown that such inoculation can be managed profitably by farmers themselves.

“…Similarly, Doni et al (2017) observed increased plant height, photosynthetic rate, chlorophyll content, stomatal conductance, and tiller and panicle numbers of rice with the application of Trichoderma enriched biofertilizer in SRI system. Moreover, Trichoderma has the potential to increase the availability of micronutrients to the plants.…”

The excessive use of chemical fertilizers and pesticides have caused several negative impacts on the environment and human health. They degrade soil fertility, build up resistance on pathogens, inhibit microbial activities and also enhance greenhouse gas emission. It is impossible and inappropriate to control plant pathogens by using chemical pesticides alone. Emphasize should be given towards organic fertilizers and pesticides to attain sustainability in agriculture. The use of Trichoderma is slowly increasing in the recent years among progressive farmers as an alternative to chemical fertilizers and pesticides. Slow rate of multiplication and colonization, susceptible to biotic and abiotic stresses, incomplete elimination of pathogens and high cost are the major problems behind its poor adoption among the farmers. To overcome these challenges different strains of Trichoderma should be identified which can multiply and colonize rapidly, least affected by environmental conditions and having wide host range on pathogens. In addition, farmers should be made aware about the importance of Trichoderma in agriculture through various extension facilities for its wide scale adoption. Trichoderma can be the viable and sustainable alternative which acts as biofertilizer, bioremediator and biocontrol agent. Nevertheless, the use of Trichoderma is limited on research activities and its application at farmers' level is not yet satisfactory. Thus, this study based on critical analysis of the research works from worldwide researchers aims to reveal the present scenario of the use of Trichoderma, its importance, modes of action, methods of application and multiplication, challenges for wide scale adoption and its appropriate solutions.

“…After inoculating with T. koningii or T. hamatum, crop productivity increase up to 300% in the field (Sanjeev et al, 2014). Recently, Doni et al (2018) reported that Trichoderma-based biofertilizer increased rice yield under system of rice intensification (SRI) conditions by 30% at very low -1 cost ha . However, the accurate reason for enhanced yields seems to be unclear yet, but in most cases, it is probably due to greater supply of nutrients by Trichoderma spp.…”

The present study aimed to investigate the biocontrol and growth enhancement potentials of Trichoderma spp., against R. solani. A total of 31 Trichoderma spp. were examined for their antagonistic potentials against R. solani in dual culture, effect of volatile and nonvolatile metabolites on the growth inhibition of test pathogen under in-vitro condition. The efficacy of Trichoderma spp. were further evaluated for controlling sheath blight and promoting rice growth under in-vivo conditions with different mode of applications. The results of in-vitro confrontation assay revealed that among the different Trichoderma spp. tested, T. harzianum (SVPRT-THLi06) and T. atroviride (SVPP-4) exhibited excellent biocontrol efficacy with 90.9% and 72.0% mycelial growth inhibition, respectively. The culture filtrate of T. harzianum (SVPRT-THLi6) at 50% was highly effective in reducing R. solani mycelial growth up to 95.9% and in case of volatile metabolites, maximum inhibition (72.5%) in mycelial growth of R. solani was recorded with T. harzianum isolate SVPP-8. A combined mode of application (soil treatment+ root dipping+ foliar spray) with T. harzianum (SVPRT-THLi06) was found most effective under greenhouse condition, which showed the least disease severity (12.4% vs control 49.6%) and disease incidence (27.1% vs control 96.4%). The present study revealed that T. harzianum (SVPRT-THLi06) has potential to control sheath blight disease as well as improve growth of rice crop. Therefore, in future it may be used as bio-based formulation for plant growth enhancement and managing sheath blight disease in rice cultivation and further may be applied in organic rice cultivation.
