Alternativa de biofertilizante como medio de cultivo para el crecimiento poblacional de dos microalgas marinas empleadas en la camaronicultura OceanDocs
Guerra Aznay, M.; Pérez Jar, L.; Leal Lorenzo, S.; Jaime Ceballos, B.; Jiménez Cabrera, R.; Pérez Díaz, S.; Bobadilla González, J..
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...

BIOFERTILIZATION WITH CHLOROPHYTA AND CYANOPHYTA: AN ALTERNATIVE FOR ORGANIC FOOD PRODUCTION Acta biol.Colomb.
ORTIZ-MORENO,Martha Lucía; SOLARTE-MURlLLO,Laura Vanessa; SANDOVAL-PARRA,Karen Ximena.
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...

Effect of Arbucula Myrrhizal Fungi on an Ecological Crop of Chili Peppers (Capsicum annuum L.) Chilean J. Agric. Res.
Castillo R,Claudia ; Sotomayor S,Leonardo ; Ortiz O,César; Leonelli C,Gina; Borie B,Fernando; Rubio H,Rosa.
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...

Efficiency of the On-Farm Mycorrhizal Inoculant and Phonolite Rock on Growth and Nutrition of Schinus terebinthifolius and Eucalyptus saligna Rev. Bras. Ciênc. Solo
Schoen,Chaiane; Aumond,Juarês José; Stürmer,Sidney Luiz.
ABSTRACT: The production of tree seedlings with high survival rate and growth is influenced by the substrate, which may be composed of biological and non-biological materials that help plant growth. The objective of this study was to evaluate the efficiency of a mycorrhizal inoculant on farm and the use of a potassic rock (phonolite) on growth and nutrition of Eucalyptus saligna Sm. and Schinus terebinthifolius Raddi under greenhouse conditions. Both species were assigned to three mycorrhizal treatments [no inoculated control (SP), no inoculation + pulp sludge and carbonized rice husk (LC), and mycorrhizal inoculant (IN)] and four phonolite rock treatments [no phonolite (F0) and addition of phonolite in particle sizes of 0.037 mm (F1), 0.074 mm (F2), and...

Growth promotion of Pinus radiata seedlings by soil inoculation and seed pretreatment with the biological control agent Clonostachys rosea Gayana Botánica
Moraga-Suazo,Priscila; Sanfuentes,Eugenio.
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....

Hydrogel, biocompost and its effect on photosynthetic activity and production of forage maize plants (Zea mays L.) Acta Agron. (Palmira)
Pedroza-Sandoval,Aurelio; Yáñez-Chávez,Luis Gerardo; Sánchez-Cohen,Ignacio; Samaniego-Gaxiola,José Alfredo; Trejo-Calzada,Ricardo.
Abstract The increase in the incidence and intensity of drought caused by climate change is a critical factor in agricultural production in some regions of the world. Dry lands are often severely affected by water shortages caused by low rainfall. This study evaluated the effect of compost and hydrogel used to retain soil moisture on photosynthetic activity and forage corn production. The experiment was designed as a randomized block with a split plot design; the main plots were the hydrogel application rates (0, 12.5 and 25 kg ha-1), and the subplots were the compost application rates (0 and 20 t ha-1). Photosynthetic activity increased by 20.2-28.0% when the hydrogel was applied at rates of 12.5 and 25 kg ha-1, respectively, compared with the control. As...

Influence of plant growth-promoting rhizobacteria (PGPR) on blackberry (Rubus glaucus Benth. cv. thornless) growth under semi-cover and field conditions Acta Agron. (Palmira)
Robledo-Buriticá,Jacobo; Aristizábal-Loaiza,Juan Carlos; Ceballos-Aguirre,Nelson; Cabra-Cendales,Teresa.
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...

Influência da biofertilização do solo com leguminosas no rendimento do arroz. Infoteca-e
MOURA, G. de M.; FREITAS, T. S. de.
Biofertilização do solo com leguminosas, até bem pouco denominada de adubação verde, possivelmente seja uma técnica tão antiga quanto à própria agricultura. Consiste na incorporação de massa vegetal oriunda de leguminosas, cultivadas no mesmo local ou fora dele, com a finalidade de restaurar o nível de fertilidade do solo. O emprego de leguminosas como biofertilizante oferece, entre outras vantagens, melhoria das propriedades físicas e químicas do solo, incorporação de matéria orgânica que resulta em humus e mineralização do nitrogênio e outros elementos com o consequente aumento do rendimento das culturas. O emprego desta prática contribuirá decisivamente para a melhoria da produtividade da cultura do arroz no Acre. Com o objetivo de se avaliar o efeito...

Mineral and organomineral fertirrigation in relation to quality of greenhouse cultivated melon Scientia Agricola
Fernandes,André Luís Teixeira; Rodrigues,Guilherme Pádua; Testezlaf,Roberto.
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...
