Crescimento de mudas de peroba rosa em resposta à inoculação com fungos micorrízicos arbusculares Ciência Rural
Machineski,Oswaldo; Balota,Elcio Liborio; Colozzi Filho,Arnaldo; Andrade,Diva Souza; Souza,José Roberto Pinto de.
O objetivo neste trabalho foi de avaliar o efeito da inoculação de fungos micorrízicos arbusculares no crescimento de mudas de peroba rosa (Aspidosperma polyneuron). O experimento foi conduzido em delineamento experimental, inteiramente casualizado, em casa de vegetação com seis repetições. Utilizou-se mistura de solo e areia (3:1), desinfestado como substrato, com os seguintes tratamentos de inoculação: Gigaspora margarita, Glomus clarum, Scutellospora heterogama, Acaulospora scrobiculata e uma mistura de fungos micorrízicos arbusculares (FMA). Após 120 dias, observou-se que a colonização micorrízica radicular foi de 28,3% a 48,4% para a mistura de FMA e para G. margarita, respectivamente. As plantas inoculadas com G. margarita e G. clarum apresentaram...

Effect of tillage systems and permanent groundcover intercropped with orange trees on soil enzyme activities BABT
Balota,Elcio Liborio; Machineski,Oswaldo; Truber,Priscila Viviane; Auler,Pedro Antonio Martins.
The objective of this study was to evaluate the effect of different soil tillage systems and groundcover crops intercropped with orange trees on soil enzyme activities. The experiment was performed in an Ultisol soil in northwestern Paraná State. Two soil tillage systems were evaluated [conventional tillage (CT) across the entire area and strip tillage (ST) with a 2-m strip width] in combination with various groundcover vegetation management systems. Soil samples were collected after five years of experimental management at a depth of 0-15 cm under the tree canopy and in the inter-row space in the following treatments: (1) CT-Calopogonium mucunoides; (2) CT-Arachis pintoi; (3) CT-Bahiagrass; (4) CT-Brachiaria humidicola; and (5) ST-B. humidicola. The soil...

Mycorrhizal effectiveness on physic nut as influenced by phosphate fertilization levels Rev. Bras. Ciênc. Solo
Balota,Elcio Liborio; Machineski,Oswaldo; Scherer,Alexandra.
In recent years, physic nut (Jatropha curcas L.) has attracted attention because of its potential for biofuel production. Although it is adapted to low-fertility soils, physic nut requires soil acidity corrections and addition of a considerable amount of fertilizer for high productivity. The objective of this research was to evaluate the effectiveness of arbuscular mycorrhizal fungi (AMF) (control without AMF inoculation, Gigaspora margarita inoculation or Glomus clarum inoculation) on increasing growth and yield of physic nut seedlings under different rates of P fertilization (0, 25, 50, 100, 200, and 400 mg kg-1 P soil) in greenhouse. The experiment was arranged in a completely randomized, block in a factorial scheme design with four replications. The...

Mycorrhizal efficiency in acerola seedlings with different levels of phosphorus BABT
Balota,Elcio Liborio; Machineski,Oswaldo; Stenzel,Neusa Maria Colauto.
The objective of this work was to evaluate the response of acerola seedlings to arbuscular mycorrhizal fungi (AMF) with different levels of phosphorus (P) additions. The experiment was carried out in greenhouse conditions, in a randomized factorial design with four treatments of AMF (control without AMF inoculation; Gigaspora margarita; Glomus manihotis; and Glomus clarum) and four phosphorus treatments (0, 30, 90, 270 mg kg-1 soil) in four replicates. The acerola plants were harvested after 120 days of the experiment. There were significant effects of arbuscular mycorrhizal fungi inoculation on the plant growth and nutrient contents in the plant shoots, mainly under lower P soil levels. Mycorrhizal plants presented a decrease of 55% of manganese content...

Physic nut plants present high mycorrhizal dependency under conditions of low phosphate availability Braz. J. Plant Physiol.
Balota,Elcio Liborio; Machineski,Oswaldo; Viviane Truber,Priscila; Scherer,Alexandra; Souza,Fabio Suano de.
The physic nut (Jatropha curcas L.) is a perennial tree that occurs naturally in the tropical and subtropical regions of Brazil. Fruits of physic nut present an oil content of 28% on a dry weight basis. Although the plant has adapted to diverse soil conditions such as low fertility, the correction of soil acidity and the addition of fertilizer are essential for highly productive plants. Thus, the response of the physic nut to different soil phosphorus levels (P) and arbuscular mycorrhizal fungi (AMF) inoculation must be characterized. Hence, the objective of the present study was to evaluate the response of physic nut seedlings to arbuscular mycorrhizal fungi (AMF) inoculation at different levels of soil P. Experiment was carried out in a greenhouse...

Resposta da acerola à inoculação de fungos micorrízicos arbusculares em solo com diferentes níveis de fósforo Bragantia
Balota,Elcio Liborio; Machineski,Oswaldo; Stenzel,Neusa Maria Colauto.
A cultura da acerola (Malpighia emarginataD.C.) tem despertado grande interesse, devido ao seu alto teor de vitamina C, com grande potencial de expansão. A cultura possui rusticidade e boa capacidade de adaptação às diferentes condições de solo e clima, entretanto, existem poucos trabalhos sobre sua nutrição. O objetivo deste trabalho foi avaliar o efeito dos fungos micorrízicos arbusculares em mudas de acerola em diferentes doses de P no solo. Foi desenvolvido um experimento em casa de vegetação, em Londrina (PR), utilizando solo arenoso (LVd) autoclavado como substrato. Os tratamentos foram instalados em esquema fatorial em vasos com capacidade de 4 kg, com tratamentos de fungos micorrízicos (Controle, Gigaspora margarita, Glomus manihotis e Glomus...

Soil carbon and nitrogen mineralization caused by pig slurry application under different soil tillage systems PAB
Balota,Elcio Liborio; Machineski,Oswaldo; Truber,Priscila Viviane.
The objective of this work was to evaluate the change in soil C and N mineralization due to successive pig slurry application under conventional tillage (CT) and no tillage (NT) systems. The experiment was carried out in a clayey Latossolo Vermelho eutrófico (Rhodic Eutrudox) in Palotina, PR, Brazil. Increasing doses of pig slurry (0, 30, 60 and 120 m³ ha-1 per year) were applied in both tillage systems, with three replicates. Half of the pig slurry was applied before summer soil preparation, and the other half before the winter crop season. The areas were cultivated with soybean (Glycine max L.) and maize (Zea mays L.) in the summers of 1998 and 1999, respectively, and with wheat (Triticum sativum Lam.) in the winters of both years. Soil samples were...

Soil microbial biomass under different tillage and levels of applied pig slurry AGRIAMBI
Balota,Elcio L.; Machineski,Oswaldo; Matos,Maria A..
ABSTRACT The objective of this work was to evaluate the changes in microbial biomass C, N and P due to the application of pig slurry under different soil tillage systems. The experiment was established in a clayey Oxisol, Eutrophic Red Latossol in Palotina, PR. Different quantities of pig slurry (0, 30, 60 and 120 m3 ha-1 year-1) were applied to the soil prior to the summer and winter crop season under conventional tillage (CT) and no tillage (NT), in three replicates. The area was cultivated with soybean (Glycine max L.) or maize (Zea mays L.) in the summer and wheat (Triticum sativum Lam.) or oat (Avena sativa L.) in the winter. The soil samples were collected in March and October of 1998 and 1999 at depths of 0-5, 5-10 and 10-20 cm. The soil tillage and...
