| Con el propósito de evaluar el humus de lombriz roja californiana Eisenia foetida como biofertilizante para el crecimiento poblacional de dos microalgas marinas, fueron cultivadas Tetraselmis tetrathele y Chaetoceros muelleri en agua de mar enriquecida con cuatro diluciones (50; 200; 350 y 500 mL) de extracto líquido de humus. La especie T. tetrathele, cultivada en la dilución de 200 mL, no mostró diferencias con el patrón medio f/2 Guillard para los parámetros: concentración celular, velocidad de crecimiento, tiempo de duplicación y productividad. C. muelleri cultivado en el mismo biofertilizante a las diluciones antes descritas, mostró un comportamiento productivo inferior al patrón, por lo que fueron evaluadas dos nuevas diluciones (550 y 650 mL). Las... |

| A bibliographic database of scientific papers published by authors affiliated to research institutions worldwide, especially focused in Europe and in the European Atlantic Area, and containing the keywords “microalga(e)” or “phytoplankton” was built. A corpus of 79,020 publications was obtained and analyzed using the Orbit Intellixir software to characterize the research trends related to microalgae markets, markets opportunities and technologies that could have important impacts on markets evolution. Six major markets opportunities, the production of biofuels, bioplastics, biofertilizers, nutraceuticals, pharmaceuticals and cosmetics, and two fast-evolving technological domains driving markets evolution, microalgae harvesting and extraction technologies... |

| ABSTRACT Chlorophyta and Cyanophyta are photosynthetic organisms characterized by their biochemical plasticity, which has allowed them to develop in different environments and have a faster growth rate than plants. Depending on the species and environmental conditions, these organisms can produce nitrogenous enzymes, for atmospheric nitrogen fixation; phosphatases, that solubilize phosphorus; phytohormones, that promote plant growth; and hygroscopic polysaccharides, that prevent erosion and improve soil characteristics. In this sense, the aim of this review was to analyze the available information on the use of Chlorophyta and Cyanophyta as biofertilizers and their potential application in organic food production. Multiple studies and researches were found... |

| Mapuche farmers in southern Chile have been cultivating local ecotypes of chili pepper (Capsicum annuum L.), called locally Cacho de cabra for many decades. It is used to make merkén, a condiment that is consumed locally and exported. This vegetable requires a nursery stage and can obtain nutritional benefits from symbiotic associations such as mycorrhizal fungi, achieving a better adaptation to transplanting. Arbuscular mycorrhizal fungi (AMF) are obligate biotrophes appearing in abundance in agroecosystems with conservation management. The aim of this study was to compare effectiveness of two AMF, a commercial mycorrhizal inoculant (IC, Glomus intraradices) and another native (IN, Glomus claroideum) with a control without inoculation (-I) on the... |

| ABSTRACT Twenty-one Clonostachys rosea strains, previously selected by its biocontrol activity higher than 80% against Fusarium circinatum, were evaluated for its ability to promote growth of Pinus radiata seedlings on natural substrate. Stem height, root length, dry weight of stem and roots, and ectomycorrhization were measured at 102 days after seeding. The results showed significant differences between some of the tested C. rosea strains when compared to the controls, showing increases for plant height of 25%, dry stem mass of 37%, root length of 13.5%, dry root mass of 20.5% and ectomycorrhization of 55% when compared to their respective controls, demonstrating a possible dual use of these strains for both plant protection and increased biomass of P.... |

| Mycorrhizal fungus inoculum produced on-farm can be used during production of woody plant seedlings to reduce costs associated with purchase of commercial inoculant and fertilization. This study aimed to test the efficiency of a mycorrhizal inoculant produced on-farm to promote growth and nutrition of woody species in combination with different levels of phosphorus. Plants were submitted to different treatments of phosphorus (0, 40 and 80 mg P/dm3) and mycorrhizal inoculation (uninoculated, and inoculation with Rhizophagus clarus [Rc] or Claroideoglomus etunicatum [Ce]). Species included were Luehea divaricata, Centrolobium robustum, Schinus terebinthifolius, Garcinia gardneriana, Cedrella fissilis, and Lafoensia pacari. The inoculum was produced using the... |

| Abstract This study shows the effect of three plant growth-promoting rhizobacteria (PGPR) strains of the genus Bacillus on blackberry (Rubus glaucus Benth.) development under semi cover and field conditions (cropping systems). Endogenous strain Bacillus subtilis GIBI-200, B. pumilus GIBI-206, its mixture (B. subtilis GIBI-200 + B. pumilus GIBI-206), and commercial strain B. subtilis QST-713 were compared to conventional mineral fertilization (Control) in each cropping system. Field condition system presented higher values (P<0.001) than semi cover in: total number of branches (7.32), number of productive branches (7.0), flowers per raceme (26.2), and the lowest percentage of unproductive branches (6.1%). Significant differences (P<0.05) were obtained... |

| Fertirrigation of melon still presents problems in relation to the type of the fertilizer used, mainly the biofertilizers. This experiment, installed in Uberaba, MG, Brazil, in a plastic module greenhouse of 768 m², tested treatments consisting of the conventional mineral fertirrigation and the organic fertirrigation, using two frequencies: daily and weekly. The best yields were obtained with daily fertilizer application, with superiority in relation to biofertilizers, with yield of 45.5 t ha-1 of fruit. This value was higher as compared to chemical products, that lead to a yield of 42.4 t ha-1. The weekly fertigation had lower productivities, and in this case, the biofertilizers also overcame the mineral, on the average 2.0 t ha-1. The best melon soluble... |

| The objective of this study was to evaluate the mycorrhizal dependency of mangaba tree (Hancornia speciosa) plantlets, under increasing levels of phosphorus fertilization. The experimental design was completely randomized in a 4×5 factorial arrangement with three mycorrhizal fungi inocula - Gigaspora margarita, Glomus etunicatum, or a pool of native mycorrhizal fungi (Acaulospora longula, Glomus clarum, Gigaspora albida, Paraglomus sp.) -, and a nonmycorrhizal control, in combination with five levels of phosphorus applied to the substrate: 0, 25, 50, 75, and 100 mg kg-1. After 180 days of growth, plantlets with inoculation of native mycorrhizal pool produced more shoot and root dry biomass and had higher shoot phosphorus content and accumulation. The... |

| Avalia o desenvolvimento inicial de plantas de milho, sorgo e milheto em casa de vegetação, sob a adubação verde com resíduos de leguminosas nativas da Caatinga Mimosa caesalpiniaefolia Bentham (sabiá), Mimosa tenuiflora (Willd.) Poir (jurema-preta) e Poincianeira pyramidalis Tul. L. P. Queiroz (catingueira) nas formas moídas e não moídas. A aplicação de adubo verde utilizando resíduos de leguminosas da catingueira, sabiá e jurema preta, incrementou variáveis biométricas, biomassa e a eficiência nutricional de plantas de milho, sorgo e milheto. O fertilizante de leguminosa à base de catingueira pode ser empregado como alternativa para adubação verde em solos degradados. As taxas médias de recuperação aparente de nitrogênio para os adubos verdes de... |
