“…Similar results were reported by Gava &Menezes (2012) andChagas Jr. et al (2014), for the treatment of seeds with Trichoderma isolates showing increased plant stand at the end of the experiment compared to the control treatment, leading to increased fruit yield of melon plant (Cucumis melo L.), and cowpea, respectively.…”

“…The central useful area related to 10 m 2 was used for the initial and final stand assessments and productivity. The effectiveness or efficiency in the use of Trichoderma to maintain the stand was calculated using the equation: E% = {1 -[Ti / Tc]} x 100, where E=% efficacy of treatment; Ti =% mean of final stand in the treatment i; Tc =% mean of final stand in the control treatment, adapted from Gava & Menezes (2012). Six plants in each plot were collected for each evaluation of biomass.…”

A B S T R A C TThe rhizosphere contains many microorganisms that can promote plant growth and protect the root system against infection by pathogens. Fungi of Trichoderma sp. are included in this group. The aim of this study was to evaluate efficiency of the inoculation of Trichoderma in agronomic performance of cowpea under field conditions, in the savanna in Gurupi, Tocantins, in harvests 2013/2014 to 2014/2015. The treatments consisted in seed treatment, with and without inoculation with Trichoderma asperellum UFT 201 with minimum concentration of viable conidia of 2x10 9 L -1 , at a dose of 20 g kg -1 of seed. Biomass evaluations were made on efficiency, initial and final stands and survival in the use of Trichoderma in the stand maintaining and productivity. The results indicated that the ability of bio-protection and plant growth promotion were of great importance for the biomass production, the stand maintaining and cowpea productivity. In both harvests, survival was superior in the plants treated with Trichoderma, 23.0 and 13.2%, respectively, and yields were 9.5% higher compared to control for the two harvests. In general, the inoculation of Trichoderma provided the best results in the biomass variables analyzed for the two crops with higher productivity.Keywords: biomass, productivity, Trichoderma, Vigna unguiculata.

O objetivo deste estudo foi avaliar a eficiência da inoculação de Trichoderma na performance agronómica de feijão-frade em condições de campo, na savana em Gurupi, Tocantins, nas campanhas de 2013/2014 a 2014/2015. Os tratamentos consistiram sementes inoculadas (ou não) com Trichoderma asperellum UFT 201 com uma concentração de conídios viáveis mínima de 2x10 9 L -1 , numa dose de 20 g kg -1 de semente. Foram efetuadas avaliações de biomassa em termos de eficiência, populações iniciais e finais e sobrevivência de Trichoderma, e na manutenção e produtividade da cultura. Os resultados indicam que a capacidade de bioproteção e promoção do crescimento vegetal foram de grande importância para a produção de biomassa, a manutenção da cultura e a produtividade de feijão-frade. E mambas as campanhas a sobrevivência foi superior nas plantas tratadas comTrichoderma, 23,0 e 13,2% respetivamente, e as produtividades foram 9,5% superiores ao controlo em ambas as campanhas. Em termos globais, a inoculação com Trichoderma providenciou os melhores resultados nas diversas variáveis ilustradoras de biomasse para as duas campanhas, conduzindo a uma maior produtividade.

The fungus Trichoderma spp. is known due to its versatility for promoting crop growth and grain yield, improving the nutrient absorption and increasing the grain yield. The objective of this work was to evaluate commercial strains of Trichoderma spp. and an organomineral fertilizer in the early growth promotion and grain yield of wheat plants. Thus, wheat seeds cv. BRS 264 were treated with 2 mL of a Trichoderma suspension (2.5 × 10 8 conidia mL -1 per 100 g seed) and submitted to growth in laboratory until 8 days after sowing (DAS). In the greenhouse experiment, the seeds were sown in an 8 L pot, which received 4.0 × 10 8 conidia of Trichoderma per pot. In both evaluations were: percentage of germination (PG), root length (RL), shoot length (SL), total length (TL), fresh root mass (FRM), fresh shoot mass (FSM), total fresh mass (TFM), dry root mass (DRM), dry shoot mass (DSM), total biomass (BIO), root mass ratio (RMR), shoot mass ratio (SMR) and aerial part/root system ratio (AP/RS). In the greenhouse experiment, paniculation and grain yield were evaluated at 110 DAS. The treatments T. harzianum ESALQ 1306 and T. asperellum URM5911 were considered satisfactory, since they provided grain yield superior to 2,000 kg ha -1 . In addition, T. harzianum ESALQ 1306 provided the best results for PG, RL, SL, TL, FRM, FSM, TFM, DRM, DSM and BIO under greenhouse conditions. The reduced biomass allocation to the root system in seedlings treated with Trichoderma ssp. occurred in the laboratory, which was confirm in greenhouse.

“…At 25 DAP was rated the initial stand and final stand at 50 DAP in ground area (6 m 2 ), which represent the five central lines (2 m 2 ) per 3 m long, 1 m distant from the border. The efficacy (E%) or control efficiency of foliar blight by treatments was calculated using the following equation: E% = {1 -[Ti / Tc]} x 100, where E% = efficiency of the treatment; Ti = % average final stand count in treatment i, Tc =% average final stand count in the control treatment (Gava & Menezes, 2012).…”

The goal of this study was to evaluate the combined inoculation of rhizobia and Trichoderma spp. in cowpea, their ability to promote growth and use as a biological control agent for foliar blight (Rhizoctonia solani). The study was conducted in a field experiment in a randomized block design with four replications. The treatments consisted of seed-applied rhizobia with and without Trichoderma spp., and to the soil at planting time and 15 days after planting (DAP). The rhizobia inoculation was performed with a mixture of strains INPA 03-11B and UFLA 03-84. For the treatments with Trichoderma spp., a commercial powder product, Trichoplus JCO was used. The application of Trichoderma spp. and rhizobia at 15 DAP, in both the seed and in the soil, showed the best results (p < 0.05). The application of Trichoderma spp. did not inhibit the nodulation process, and the best results were obtained when the fungus was inoculated with rhizobia. The inoculation treatments were positive for Trichoderma spp. The Trichoderma spp. treatments showed improvements in stand counts, survival and effectiveness against R. solani, reinforcing that the usage of Trichoderma spp. as a seed and soil treatment.
