Performance of an Otto cycle engine using biogas as fuel

Due to the rising price of petroleum, researches looking for alternative fuels are intensifying more and more. Brazil has a great availability of biogas from anaerobic digestion of waste in rural areas, of urban waste in landfills and of sewage treatment systems on urban centers. In this paper, an Otto cycle engine was evaluated on a dynamometer, fed with biogas, generating the characteristic curves of the engine for...

Analysis of frictional properties of cereal seeds

The thickness, width, length and weight of cereal seeds (wheat, rye, barley, oats and triticale) and their external friction angles on three types of surfaces – steel, methyl polyacrylate and rubber – were determined. The experiment was performed with the use of a new device that measures the angle of external friction and the time taken by seeds to travel a given distance, which supports the determination...

In vitro interaction between fungicides and beneficial plant growth promoting Rhizobacteria

Laboratory experiments were conducted to study the effects of five fungicides on the growth of Bradirhizobium japonicum and Phosphate solublizing bacteria (PSB) at different concentrations that is, (0, 0.1, 0.2, 0.3, 0.4 and 0.5%). Fungicide effects on bacteria were determined on the basis of their growth in respective medium. The population of B. japonicum declined significantly while PSB population showed...

Effect of cultural techniques: Rotation and fallow on the distribution of Oedaleus senegalensis (Krauss, 1877) (Orthoptera: Acrididae) in Senegal

The Senegalese grasshopper, Oedaleus senegalensis Krauss is a major pest in Sahel of West Africa. The present work reports the insect distribution and cultural techniques influence within two Senegalese localities. Methodology used is based on sampling and density estimates for a comprehensive study of Senegalese grasshopper in natural environment. Adult density was evaluated by visual counting on 100 m paths and larva...

Stability of soybean yield and quality components

Varieties of testing are very important so we could evaluate which varieties are the best solution for the specific growing region. The aim of this research was to determine stability and correlations between yield, protein content and oil content in soybean cultivars. The research was carried out on ten NS soybean cultivars in 2009 and 2010. All of the analysed traits significantly varied depending on cultivar and...

Metroglyph analysis of maize (Zea mays L.) inbreds for preliminary classification and group constellation

When a large number of accessions are available it is often useful to represent them on two dimensional graph and form preliminary groups which are subsequently subjected to more detailed stratification for specific breeding purposes. In the present investigation inbreds were grouped in to clusters using metroglyph analysis. Index scores were assigned to each glyph to arrive at conclusions about the agronomic potential...

Effects of vinasse irrigation on effluent ionic concentration in Brazilian Oxisols

The irrigation with vinasse can improve soil fertility. However, this use should take into account the characteristics of each soil because the vinasse has unbalanced amounts of mineral and organic elements which might lead to leach the ions, especially nitrate and potassium.  The purpose of this study was to evaluate the impacts of vinasse irrigation on effluent ionic concentrations in Brazilian Ferralsols from...

Assessment of causes that contribute to the occurrence of plantations forests fires in Niassa Province, North of Mozambique

Although, Niassa province has natural potential for exotic plantations introduction, forest fires have proved to be a very compromising factor in attracting investments for commercial forestation. Only in two years, fires have devastated approximately 2887.8 ha of Pinus sp. and Eucalyptus sp. of the Chikweti Forests Company. This research was conducted in order to assess the main causes that contribute to the fire...

Effect of nitrogen and phosphorus fertilizers on some soil properties and grain yield of maize (BH-140) at Chiro, Western Hararghe, Ethiopia

An experiment was conducted during the main rainy seasons of 2008 to 2010 at Haramaya University Chiro Campus to determine the response of BH-140 to N and P application and their interaction on some soil properties. Soil samples were taken from 0-30 cm depth before sowing and were analyzed for soil texture, pH, cation exchange capacity (CEC), total N, OC and available P. Five levels of each nutrient: 0, 25, 50, 75 and...

Identification of Pratylenchus spp. in soybean in Central region of Brazil using the ITS-5.8S rDNA region

Root-lesion nematodes are a serious yield-reducing disease of many crops in many parts of the world. The aim of this study was identify populations of Pratylenchus spp. in different soybean fields in the Central region of Brazil based upon sequence analyze of ITS-5.8S rDNA region and comparison on GenBank by BLAST. The results showed that a total of 10 nematodes populations showed similarity with Pratylenchus brachyurus...
