| Biosurfactant are surface active compounds with emulsifying capacity and are produced by microorganisms, and they may be affected by factors related to microbial cultivation, such as pH, salinity, incubation time, carbon and nitrogen sources. The aim of this work was to study the influence of the culture conditions on the production of biosurfactants by Phialemonium sp using agroindustrial wastes. The processing parameters of temperature, humidity and pH produced the most significant effects on the production of biosurfactant and emulsifying activity. The maximum concentration of biosurfactant obtained in this study was equivalent to a surface tension reduction of 8.5 mg L-1 surfactin commercial solution using wheat bran, pH of 4.5, and 0.5% of soybean oil... |

| Combine header loss comprises more than 50% of wheat harvesting losses. Therefore, decline in this part of the loss to the extent allowed amount is an important step in reducing of crop wastes. Combine header is a complex system in which several factors are involved in its work. And, if these factors can be adjusted and controlled to suit the working conditions, to a large extent of crop loss can be prevented during the harvest. In this study, reel index, cutting height of crop and horizontal and vertical distance of reel from cutter bar were selected as the effective factors in header loss. In response surface method, central composite design was used to modeling and finding optimal levels of mentioned factors. The results showed that power model... |

| Heavy crop residue on the soil surface impedes no-till drill performance and subsequent crop production in conservation tillage systems and therefore limit its adoption by farmers. Therefore, a field study was conducted to determine the effects of various residue management methods on no-till drill performance. The experimental design was a randomized complete block in five replications. The residue management systems were in four levels of leaving (R.M1), removing (R.M2), chopping (R.M3) and disking (R.M4). Factor analysis was used to group and identify the most effective indicators of drill performance. The results showed that various residue management methods had a significant effect on sowing depth, speed of emergence, effective field capacity, and... |

| Wheat is one of the most important food staff in consumption pattern of each country. More than 50% of human energy is supplied from bread in developing countries. Reducing of losses and waists in combine harvesting resulte increasing considerable wheat production in country. Combine loss is less than 2%-3% in developed countries, while that of developing countries is about 15%-20% in different regions and circumstances of harvesting seasons and field conditions. Regarding to research finding that maximum total combine losses are related to combine header loss, so it is necessary to determine precise losses and their causes to improve and modify existing combine's technical characteristics. In this national research project that took place in three... |

| Cereal quality preservation is traditionally the accountability of grain storekeepers who count on profound knowledge discovered through scientific research. The main purpose of this research study was to predict the evolution of wheat temperature in unaerated silo during storage period under Tunisia climate. First, a bidimensional mathematical combined model (silo wall model + heat transfer model in grain bulk), which describes the distribution of the unsteady temperature in a cylindrical grain storage system, was presented and simulated using the parabolic solver incorporated in the Matlab 2015a environment. Mesh refinement at the shortest boundaries, including triangular elements, was adopted to simulate storage temperatures. In this numerical model,... |

| Five wheat genotypes including two commercial cultivars (Mist1 and Misr2) and three Ug99-race specific genes (Sr24, Sr25, and Sr31) were screened for stem rust resistance based on phenotypic and genotypic reaction. Based on phenotypic reaction, Sr24 (LcSr24Ag) and Sr31 (Seri-82) exhibited seeding and adult plant resistance while the wheat cultivars, Misr1 and Misr2 were susceptible. Sr25 Agatha (CI 14048)/9*LMPG-6 DK16 exhibited seedling resistance while showed susceptibility at adult plant stage. Based on genotypic reaction, DNA markers showed that gene Sr25 was only found to be present in Misr1 and Misr2 while Sr24 and Sr31 were absent in both cultivars. Although, virulence to Sr25 was detected. However, avirulence to Sr24 remains this gene as a suitable... |

| The starch composition of bread making wheat seeds (Triticum aestivum subsp. vulgare) of the Argentine commercial varieties Buck Charrua, Buck Ombú, Buck Guaraní, Buck Catriel and Buck Poncho was analyzed by two different methods. One of these depends on the differential solubility of amylose and amylopectin in a water:butanol mixture whilst the other process is based on the use of the lectin Concanavalin A. These methods were complemented by spectrophotometric determinations to enable the identification of the á-D- glucanes and also improved the comparative quantitation of the amylose and amylopectin fractions. As a result of this, no significant variations for starch content (ANOVA, F4- 8= 0.7; p ≥ 0.05) were found among these varieties,... |

| Clean fallowing has been criticized in the recent past due to the fact that it causes accelerated soil erosion, emission of CO2 to the atmosphere and reduction in farm income. In an effort to reduce fallowing in Pothwar, Pakistan, field experiments were carried out from 2005 through 2008 at three locations (Rawalpindi, Chakwal and Fateh Jang). The experimental design was split-plot and treatments were applied as follows: conventional cultivator, moldboard plow and minimum tillage in main plots; fallow, legume (mungbean, Vigna radiata) and mulch of wheat straw were used in sub plots. Wheat (Triticum aestivum) was planted in all the subplots during winter. All the treatment plots had equivalent volumetric water content at wheat planting. Consequently, the... |
