“…These results confirm recent reports suggesting increased early root colonization of field grown tomato following pre-inoculation contributing to plant nutrition, growth and yield (Conversa et al 2013). Although cover crops did not significantly affect root colonization, tomato crop grown after V. villosa showed higher root colonization at flowering compared to B. juncea.…”

“…Numerous studies have reported the positive effects of AMF inoculation on crop production both in pot and field experiments and especially when indigenous AMF populations are low or not sufficiently infective (Conversa et al 2013;Douds et al 2007;Wagg et al 2011). Whilst the introduced strains are generally considered 'symbiotically superior' (more infective and efficient than the native strains), some studies have reported neutral or even negative results following inoculation, which could be attributed to introduction of less competitive AMF isolates compared to native ones (Garland et al 2011;Muok et al 2009).…”

Contrasting effects of cover crops on ‘hot spot’ arbuscular mycorrhizal fungal communities in organic tomato

Arbuscular mycorrhizal fungal (AMF) communities are fundamental in organic cropping systems where they provide essential agro-ecosystem services, improving soil fertility and sustaining crop production. They are affected by agronomic practices, but still, scanty information is available about the role of specific crops, crop rotations and the use of winter cover crops on the AMF community compositions at the field sites. A field experiment was conducted to elucidate the role of diversified cover crops and AMF inoculation on AMF diversity in organic tomato. Tomato, pre-inoculated at nursery with two AMF isolates, was grown following four cover crop treatments: Indian mustard, hairy vetch, a mixture of seven species and a fallow. Tomato root colonization at flowering was more affected by AMF pre-transplant inoculation than by the cover crop treatments. An enormous species richness was found by morphological spore identification: 58 AMF species belonging to 14 genera, with 46 and 53 species retrieved at the end of cover crop cycle and at tomato harvest, respectively. At both sampling times, AMF spore abundance was highest in hairy vetch, but after tomato harvest, AMF species richness and diversity were lower in hairy vetch than in the cover crop mixture and in the mustard treatments. A higher AMF diversity was found at tomato harvest, compared with the end of the cover crop cycle, independent of the cover crop and pre-transplant AMF inoculation. Our findings suggest that seasonal and environmental factors play a major role on AMF abundance and diversity than short-term agronomic practices, including AMF inoculation. The huge AMF diversity is explained by the field history and the Mediterranean environment, where species characteristic of temperate and sub-tropical climates co-occur.

“…Tomato is particularly responsive to AMF inoculation, and previous work has shown effects on plant growth, nutrient contents or yield also in combination with NPK fertilizer or different P levels (Poulton et al, 2002;Mujica et al, 2010;Conversa et al, 2013). However, the combination of AMF with a full fertilizer program for industrial tomato production in the field has not yet been evaluated.…”

The effect of arbuscular mycorrhizal fungi (AMF) on industrial tomato (Lycopersicon esculentum Mill. cv. Isma F1) cultivated in North-Eastern Algeria was evaluated under greenhouse and field conditions in a vertisol soil intended for the cultivation of industrial tomato. In the greenhouse, a commercial AMF inoculum and native fungal isolates consisting of Funneliformis mosseae and Septoglomus constrictum, were added in sterilized or non-sterilized soil and tested for their effects on the growth of tomato. Inoculation with exotic AMF in the commercial inoculum or with native isolates had similar effects in increasing mycorrhizal root colonization rates and tomato growth. In the field, the commercial AMF inoculant was combined with three rates of chemical fertilizer used for the cultivation of industrial tomato (mono-ammonium phosphate, ammonium sulphate and NPK, applied at 0, 50 and 100% of the recommended dose). Introduced AMF significantly improved mycorrhizal root colonization levels, growth and yield as compared to the indigenous AMF alone. In addition, in the presence of the mycorrhizal inoculant, an application of 50% of recommended fertilizer dose provided the same yield as the full fertilizer dose without inoculation. Results clearly show that in this soil, plants needed both fertilization and AMF inoculation to achieve optimal growth and yield, and that the application of AMF can compensate for the reduction in chemical fertilizers, offering a more sustainable farming system that is respectful of the environment.

“…A interação da inoculação com FMA e adição de SHs apresentou um efeito sinergético no desenvolvimento desta planta. Nos estudos de Conversa et al (2013), Hart et al (2015) e Bona et al (2017), afirmaram que a aplicação de algumas espécies de FMAs como biofertilizante para o tomateiro é considerada uma prática inovadora e eco-sustentável, aumentando a rentabilidade dos produtores e reduzindo a necessidade de aplicação de fertilizantes fosfatados e aumenta a qualidade industrial e nutricional do tomate. Isso foi observado no presente estudo com o aumento da MSPA, MST, IC e PPA nas plantas inoculadas com o FMA R. clarus e ou com a adição de SHs.…”

Resumo -A utilização de fungos micorrízicos arbusculares (FMAs) pode otimizar a produção, uma vez que a simbiose entre o fungo e a planta pode promover o aumento da absorção de nutrientes. O objetivo deste estudo foi avaliar o efeito da inoculação de fungo micorrízico arbuscular e a adição de substâncias húmicas (SHs) na cultura do tomateiro. Para isso, foram avaliados: a densidade dos esporos, a colonização radicular por FMA, a produção de fitomassa, o índice de clorofila e o conteúdo de fósforo na parte aérea. O delineamento experimental foi inteiramente casualizado com quatro tratamentos e cinco repetições em vasos com 3 L de substrato (areia + vermiculita 1:1 v/v, estéril) em casa de vegetação da Universidade Paranaense -UNIPAR, Umuarama, PR. Os tratamentos foram os seguintes: 1 -sem inoculação de FMA e sem adição de SHs, 2 -com inoculação de FMA e sem adição de SHs, 3 -sem inoculação de FMA e adição de SHs, 4 -com inoculação de FMA e adição de SHs. A densidade de esporos, a colonização radicular por FMA, a massa seca da parte aérea e total e o conteúdo de fósforo das folhas foram aumentados significantemente com a inoculação de FMAs e adição de SHs. O índice de clorofila aumentou significantemente a adição de SHs. Conclui-se que com a inoculação de FMAs e adição de SHs promove o crescimento e o aumento do conteúdo de fósforo na planta de tomateiro. Palavras-chave: ácido fúlvico, ácido húmico, Rhizophagus clarus.Abstract -The utilization of arbuscular mycorrhizal fungi (AMF) can improve plant production, due the symbiosis between the fungus and plants can promote the increasing of nutrient uptake. This study aimed to evaluate the effect of AMF inoculation and the addition of humic substances (HSs) in tomato cultivation. For this, it has been analyzed the density of spores and the root colonization by the AMF, phytomass' production, the chlorophyll index and the content of phosphorus of aerial part. The experiment has been fully made with four treatments and five repetitions in three-litter-pot of substrate (sand + vermiculite 1:1 v/v, sterile) in the greenhouse at Universidade Paranaense -UNIPAR in Umuarama, Paraná State. The treatments have been the following: 1 -with no inoculation of AMF and with no addiction of HSs, 2 -with inoculation of AMF and with no addiction of HSs, 3 -with no inoculation of AMF and addiction of HSs, 4 -with inoculation of AMF and addiction of HSs. The density of spores and the radicular colonization by AMF, the dry mass of aerial part and total, the content of phosphorus in aerial part, have increased significantly with the inoculation of AMF and addiction of HSs. The chlorophyll index has increased significantly the addiction of SHs. Concluded that the inoculation of AMF and addiction of HSs it promotes the growth and the increase of phosphorus content in the tomato plant.
