It is one of the major components of the Brazilian diet and an important protein source. Regarding the nitrogen supply for the bean, we can mention the use of mineral fertilizers and biological fixation of N2. The fixation efficiency is variable, ranging from 2 to 100 kg N ha-1. Thus it is justified the researches that involve the use of mineral nitrogen fixation with N. The objective of this study was to evaluate doses of nitrogen in the bean cultivation in field conditions, associated with seed inoculation. The study was conducted under field conditions in two traditional bean cultivation area in Paraná northern. The experiment was consisted by plots with or without inoculation of Rhizobium tropici in the seeds and use five N rates (0, 20, 40, 60 and 80 kg ha-1) in cover. The experimental design employed was randomized blocks, being the factorially treatments disposed in five levels of nitrogen with and without inoculation. Evaluations were made about the nodulation, N content in leaves, shoot dry matter, N uptake, number of pods per plant and grain yield. The results showed that application of nitrogen coverage or use of the inoculant did not provide income gains in the bean. Nodulation was affected by the application of mineral nitrogen coverage. The performance of bean differed in the two cultivated areas, which may have been influenced by climatic conditions and management at the sites studied. / O feijão representa uma importante fonte protéica na dieta humana dos países em desenvolvimento das regiões tropicais e subtropicais. No Brasil, o feijão é um dos componentes básicos da dieta alimentar da população e importante fonte de proteína. Com relação ao fornecimento de nitrogênio (N) para o feijoeiro pode ser destacado o uso de fertilizantes minerais e a fixação biológica de N2. A eficiência da fixação biológica é muito variável, oscilando de 2 a 100 kg de N ha-1. Desta forma justificam-se trabalhos que busquem associar o uso do nitrogênio mineral com a fixação biológica de N. O objetivo deste trabalho foi o de avaliar doses de nitrogênio em cobertura no cultivo do feijão em condições de campo, associado a inoculação de sementes. O estudo foi conduzido em condições de campo em duas áreas de cultivo tradicional de feijoeiro, na região norte do Paraná. O experimento foi constituído por parcelas com ou sem inoculação de Rhizobium tropici nas sementes e utilização de cinco doses de N (0, 20, 40, 60 e 80 kg ha-1) em cobertura. O delineamento experimental empregado foi de blocos ao acaso sendo os tratamentos arranjados fatorialmente em 5 doses de nitrogênio com e sem inoculante. Foram feitas avaliações quanto a nodulação, teor de N nas folhas, matéria seca da parte aérea, N acumulado, número de vagens por planta e rendimento de grãos. Os resultados encontrados revelaram que a aplicação do nitrogênio em cobertura ou utilização do inoculante não proporcionou ganhos de rendimento no feijoeiro. A nodulação foi afetada pela aplicação de nitrogênio mineral em cobertura. O desempenho do feijoeiro diferenciou-se nas duas áreas cultivadas, o que pode ter sido influenciado pelas condições climáticas e de manejo nos locais estudados.

A produção de biocombustíveis a partir das microalgas vem se tornando promissora por ser uma fonte renovável, não poluente e por não competir com áreas de cultivo de alimentos. Devido à exaustão das fontes fósseis e à alta demanda por combustível de origem renovável e não poluente, as microalgas vêm despertando interesse nos cenários energético e ambiental. Por outro lado, existe um elevado custo no cultivo das mesmas, fazendo-se necessário estudos para desenvolvimento de novos reatores, meios de cultivos, técnicas de colheita, de extração de lipídios, transesterificação e também a implementação do conceito de biorrefinaria. Levando em conta o interesse crescente na utilização das microalgas como matéria prima na produção de biocombustíveis e a necessidade de estudos que torne o cultivo das microalgas em grande escala economicamente viável, esta pesquisa teve como objetivo determinar as melhores condições para o cultivo da microalga Chlorella vulgaris, buscando uma maior produtividade de biomassa e de lipídios. Os fatores avaliados foram: tempo de luminosidade, reciclo da biomassa após extração de lipídios e concentração de nutrientes (NaNO3, K2HPO4, KH2PO4 e glicerol) no meio de cultivo, em um arranjo ortogonal de Taguchi L8. De acordo com os resultados, identificou-se uma maior relevância, para a produtividade de biomassa, a utilização de glicerol e luminosidade (12 h), seguido do NaNO3 em alta concentração. A utilização de biomassa extraída mostrou-se inviável para o processo de cultivo, e a utilização de K2HPO4, KH2PO4 foram pouco influentes, porém essenciais. Paralelamente foi avaliado a viabilidade em se utilizar o efluente da Estação de Tratamento de Esgoto (ETE) da Escola de Engenharia de Lorena (EEL-USP) como meio de cultivo em um reator de PVC, construído para cultivo heterotrófico, no qual obteve-se uma alta produtividade de biomassa (0,20 g.L-1.d-1) e de lipídios (83,35 mg.L-1.d-1), se comparados a outros processos. / The production of biofuels from microalgae has become promising because it is a renewable, non-polluting source and because it does not compete with food growing areas. Due to the exhaustion of fossil fuel sources and the high demand of fuel from renewable and non-polluting origin, microalgae have been attracting interest in the energy and environmental scenarios. On the other hand, there is a high cost to cultivate microalgae, making necessary studies for the development of new reactors, culture media, harvesting techniques, lipid extraction, transesterification and also the implementation of the biorefinery concept. Taking the growing interest in the use of microalgae as a raw material in the production of biofuels and the need of studies to make large-scale microalgae cultivation economically viable, this research aimed to determination of the best conditions for the cultivation of microalga Chlorella vulgaris, seeking a higher productivity of biomass and lipids. The factors evaluated were: time of luminosity, biomass recycling after lipid extraction and nutrient concentration (NaNO3, K2HPO4, KH2PO4 and glycerol) in the culture medium using a orthogonal arrangement of Taguchi L8. According to the results, a greater relevance was identified for biomass productivity, the use of glycerol and luminosity (12 h), followed by NaNO3 in high concentration. The use of extracted biomass proved to be impractical for the process, and the use of K2HPO4, KH2PO4 was weak but essential. In parallel, the feasibility of using the effluent of the Effluent Treatment Plant (ETP) on Escola de Engenharia de Lorena (EEL-USP) as a culture medium for a PVC reactor, built for heterotrophic cultivation. It was obtained higger productivity of biomass (0.20 g.L-1.d-1) and lipids (83.35 mg.L-1.d-1) from it, if you compare to others process.

The Spanish slug, Arion vulgaris, is an invasive species in Sweden and the rest of northern Europe, dispersing rapidly and widely and it has become a significant pest for both gardening enthusiasts and commercial farmers. In this study, I examined the relationship between dispersal movements and temperature, relative humidity, illuminance, and individual body mass of the slugs. The investigation was based on data from a field experiment where PIT-tagged slugs were telemetrically tracked for 12 hours and data from the experiment were used to develop a model for how the local dispersal movement of the slugs was affected by the environmental factors. There was no correlation between slug body mass and dispersal movement. Movement decreases with increasing temperature in the range 14–19°C. Movement was similarly affected by illuminance. Relative humidity did not have a significant effect on movement. Spanish slug actively moves between adjacent gardens and within plantations, and the local dispersal has an impact on the extent of damage it causes in gardens and farms. It is therefore important to gain knowledge about what affects the local dispersal. This study contributes to that knowledge. / Mördarsnigeln, Arion vulgaris, är en invasiv art i Sverige och övriga Nordeuropa, med snabb och vid spridning och den har blivit ett betydande skadedjur för både trädgårdsentusiaster och kommersiella odlare. I den här studien undersökte jag sambandet mellan förflyttning och temperatur, relativ luftfuktighet, ljus samt sniglarnas massa. Undersökningen baserades på data från ett fältförsök där PIT-märkta sniglar spårades telemetrisk under 12 timmar och data från försöket användes för att ta fram en modell för hur sniglarnas förflyttning påverkades av miljöfaktorerna. Det fanns inte något samband mellan massan hos sniglarna och deras förflyttning. Förflyttningen minskade med ökande temperatur i intervallet 14–19°C. Förflyttningen påverkades på liknande sätt av illuminans. Relativ luftfuktighet hade inte en signifikant påverkan på förflyttning. Mellan närliggande trädgårdar och inom odlingar förflyttar sig mördarsniglar aktivt och den lokala spridningen har betydelse för hur stora skador som uppstår inom odlingar. Det är därför viktigt att få kunskap om vad som påverkar mördarsnigelns spridning, även på en mer lokal nivå, vilket den här studien bidrar till.

To produce enough food for a growing population, soil remediation is crucial unless more forests are to be cleared to make way for agriculture land. Finely ground rocks have been proposed as a soil amendment for highly weathered soils. In Chontales, Nicaragua most of the forest has been converted to cattle pasture. In fertile soils, crop agriculture is more lucrative per unit of area than cattle grazing, but the low nutrient content of Chontales soils makes it uneconomic. The purpose of the study was to examine whether incorporation of rock dust is a sustainable way to increase the fertility in Chontales and thus can be part of a strategy that encourages farmers to adopt crop agriculture as an alternative to animal husbandry. A field experiment was conducted in which basaltic rock dust and compost was applied to soil for cultivation of common beans. Three sustainability parameters were analyzed and the diffusion potential of the proposed technology was assessed. The experiment failed to confirm the positive result obtained in previous studies on yield in similar soils and no correlation between pest resistance and rock dust applications was found. The failure to produce a confident result on yield was partly due to a leaf hoppers invasion and harm caused by intruding calves into the experiment site. Rock dust was found to be typically free of toxic agents and little environmental damage is associated with the practice, provided that the source of extraction is close to the application site. The relative disadvantage in terms of social prestige and incompatibility with the current cattle oriented production system were found to be the main obstacles for diffusion of the technique in Chontales.

The introduction of trout has been implicated in the declines in native fish fauna in New Zealand and worldwide. Since the introduction of brown (Salmo trutta) and rainbow (Oncorhynchus mykiss) trout to New Zealand in 1867, their distribution has spread and they have been implicated in the fragmentation of native fish distributions, particularly native non-migratory galaxiids. However, in the Upper Waimakariri basin the co-occurrence of trout and galaxiid populations is relatively common, even in streams where trout reach sizes known to be piscivorous. To investigate mechanisms that may regulate trout and galaxiid co-occurrence, I investigated differences in antipredator behaviour and growth rate between stream types with varying levels of trout presence. Using quantitative survey data collected between 1997 and 2006, I found that trout abundance was low and varied annually in frequently disturbed sites compared their high abundance in stable streams. This finding was used to classify streams into three population types, barrier (trout absent), disturbed (trout presence intermittent) and sympatric (constant trout presence). Using this classification, I tested the effects of trout chemical cues on galaxiid activity and refuge use in artificial channels. There were no differences in activity or refuge use between trout odour and there were no effects of population type or galaxiid size during both the day and the night. Using otolith weight-fish length relationships in galaxiids collected from each population type, I found that galaxiid growth rate was higher in disturbed streams than in stable streams either with or without trout. An experiment manipulating trout size and presence, over two months in a natural stream, found galaxiids from treatments without trout grew slower than those with trout. Slow growth rates in galaxiids above trout-migration barriers and in sympatry, combined with low growth rates in treatments without trout suggest that the mechanisms that regulate galaxiid growth are more complex than previously thought.

The purpose of this report was to investigate bamboo (Bambusa vulgaris) and to gain a wider knowledge about bamboo as a construction material. A growing problem all over the world is global warming caused by carbon dioxide emissions. Bamboo is a giant grass and can absorb more carbon dioxide in comparison to same-sized trees. The majority of bamboo species growing in Ghana is Bambusa vulgaris. The results are based on six qualitative semi-structured interviews conducted in Ghana and five supplementary interviews by e-mail conversations. The investigation was carried out in Greater Accra region, Ashanti region, and Western region in Ghana. The results of this survey showed that Bambusa vulgaris has the best properties for construction at four years of age and needs treatment to last longer than two years. The interviews also revealed that there is currently no example of a built corrugated bamboo roof in the country, instead traditional bamboo roofs are common in the rural areas. Natural material needs to increase in the urban areas for environmental purposes because cement and metal are standard material in the Greater Accra region. Therefore, roofing with bamboo can be a good idea. If bamboo becomes the main building material, it is possible that bamboo plantation will expand in Ghana and that contributing to overall reduced the CO2 emissions. The conclusion is to build with four year old bamboos and use bamboo instead of wood or traditional bamboo roofs as alternatives to corrugated bamboo roofing sheets in the country.

A integração de métodos como a diversificação de culturas e a utilização da biotecnologia que aumentem a produtividade de grãos do arroz e feijão pode contribuir ambientalmente e economicamente na adoção de sistemas de produção agrícolas mais sustentáveis. Assim, o objetivo do trabalho foi avaliar o efeito de diferentes culturas antecessoras (milho e/ou Urochloa ruziziensis) e inoculação de Azospirillum brasilense sobre o desenvolvimento e a produtividade do arroz de terras altas e do feijão cultivado em sucessão, além da inoculação de Rhizobium tropici na cultura do feijão de inverno. O estudo foi realizado no município de Selvíria-MS, em um LATOSSOLO VERMELHO Distrófico em área de plantio direto há mais de 10 anos. O delineamento experimental utilizado foi o de blocos casualisados, disposto em esquema de faixas, com quatro repetições. Os tratamentos foram constituídos pelo arranjo de oito combinações de milho e Urochloa ruziziensis e ausência ou presença de inoculação com Azospirillum brasilense. Durante a condução do experimento foram realizadas as seguintes avaliações: características agronômicas, componentes de produção e produtividade das culturas do arroz e feijão. O cultivo antecessor de Urochloa ruziziensis propiciou plantas mais altas e com maior teor de nitrogênio e plantas de feijão com maior número de vagens. As diferentes culturas antecessoras utilizadas não influenciaram na produtividade de grãos do arroz de terras altas e do feijão de inverno. A inoculação de sementes de arroz com Azospirillum brasilense promoveu incremento de 19% na produtividade de grãos de arroz de terras altas e, consequentemente, seu efeito resultou em incremento de aproximadamente 25% na produtividade do feijoeiro de inverno inoculado com Rhizobium tropici. / Among the grains of importance in the world scenario, rice and common bean should be highlighted as part of the basic diet of Brazilians. The integration of methods such as crop diversification and the use of biotechnology that increase grain yield of rice and common bean can contribute environmentally and economically to the adoption of more sustainable agricultural production systems. The objective of this work was to evaluate the effect of different predecessor crops (corn e/ou Urochloa ruziziensis) and inoculation of Azospirillum brasilense on the development and productivity of upland rice and common bean grown in succession, as well as the inoculation of Rhizobium tropici on winter common bean crop. The study was carried out in Selvíria-MS country, in a Red Latosol Distrofic in no-tillage area for more than 10 years. The experimental design was randomized blocks, arranged in strips scheme, with four replications. The treatments were constituted by the arrangement of eight combinations of the corn and Urochloa ruziziensis and absence or presence of inoculation with Azospirillum brasilense. During the conduction of the experiment the following evaluations were carried out: agronomic characteristics, production components and yield of rice and bean crops. The predecessor crop of Urochloa ruziziensis provided higher plants with higher nitrogen content and bean plants with higher number of pods. The different predecessor crops used did not influence grain yield of upland rice and winter common bean. The inoculation of rice seeds with Azospirillum brasilense promoted a 19% increase in the productivity of upland rice grains and, consequently, its effect resulted in an increase of approximately 25% in the yield of winter common bean inoculated with Rhizobium tropici.
