| An existing 1.5kW brush cutter was modified and evaluated with the view to adapt a low-cost rice harvesting machine. The modifications included replacing existing blade with circular saw blade, incorporating a guider and a driver to lay down the harvested crop in swath and attachment of a harness belt for easy and comfortable operation. The machine was evaluated keeping in view major influencing factors i.e., crop establishment (conventional transplanting, system of rice intensification (SRI), and mechanical transplanting), blade type (B1: 40 teeth, pitch 1.92 and B2: 80 teeth, pitch 0.96) and straw moisture content (38-42, 33-37 and 28-32%, w.b). The results showed that the height of cut was significantly affected (p<0.05) by the crop... |

| Swine farming emit several odorous volatile organic compounds, one of which is p-cresol. Considering the layout of a swine barn, adsorption is one of the most suitable technologies for mitigating organic pollutants. In this study, commercial granular activated carbon (GAC) was tested as an adsorbent for removing p-cresol from aqueous solution. The objectives were to: 1) determine the combined effect of temperature, pH, and adsorbent dose on adsorption, (2) investigate the effect of volatile fatty acids and aldehydes on adsorption of p-cresol, (3) determine adsorption kinetics and isotherms, (4) study the effect of solvent on adsorption, (5) propose a possible mechanism of adsorption, and (6) discuss practical implications and design calculations for... |

| Corn earworm is a major pest of sweet corn, especially when grown organically. Aerial application of insecticides is important for both conventionally- and organically-grown sweet corn production as sweet corn is frequently irrigated to assure return on investment given the high production costs. Aerial insecticide application costs can be minimized through use of reduced spray rates if insecticide efficacy can be maintained at the lower spray rates. The objectives of the study were to characterize deposition on field corn silks when applied at 47.9 L/ha (with VMDs at 230 and 400 μm) and 86.2 L/ha (with VMD at 400 μm) spray rates. Applications of the bioinsecticide, Gemstar®, and the insecticide, Entrust®, which are both approved for use in organic... |

| A variety of methods, ranging from natural to artificial, which have been practiced for producing agarwood and the economic opportunity related with this field in Bangladesh were reviewed. The anatomy of agar tree was also described. Agarwood is the fragrant resin-infused wood derived from the wounded trees of Aquilaria species. It is a valuable non-timber forest product used in fragrances and medicine. Artificial agarwood inducing methods serve as a way to supply agarwood and conserve the wild Aquilaria stock. The existing artificial methods are Nailing, Drilling, Aeration, Agar-wit, Partly-Trunk-Pruning, Burning-Chisel-Drilling, Fungi-Inoculation, etc. The quality of agar mostly depends on the plant species and the fungal species, as well as certain... |

| The pepper tree (Schinus terebinthifolius) is a tree native to Atlantic whose planting is seen as an alternative to agricultural diversification. Besides being suitable for reforestation, its fruit, known as pink pepper, pepper or brazilia-poivre rose, is widely used in European cuisine. This paper aimed to design an agribusiness for processing the fruits of 100 trees planted in planting planned or consortium, as well as restore degraded areas, this needs a small area for planting. Lining surveyed the procedures used for drying of pink pepper as well as those required for the marketing of this spice patterns. The starting process is the manual collection and pre-cleaning stage where pepper is separated from branches and leaves, the product follows after... |

| spray drift associated with agrochemical operations is highly dependent upon the physical properties of the spray solution with respect to how they influence atomization. This study examined two spray solutions across a wide range of solution temperatures for two nozzles spraying into two high speed airstreams. The dynamic surface tension and viscosity of the spray solutions were also measured across the range of temperatures. Generally as the solution temperature increased, the dynamic surface tension and viscosity both decreased. This decrease in physical properties was directly related to the decrease in spray droplet size for all nozzles and airspeeds tested. Monitoring of spray solution temperature throughout the spray system of a typical... |

| The study on osmotic pretreatment of oyster mushrooms was carried out in order to remove the moisture prior to further mechanical drying. Three salt concentration level (10, 15 and 20 g/100 g), two temperature levels of osmotic solution (30 and 45°C) and constant solution to mushroom ratio of 10 (w/v) were selected and the observations on water loss and solid gain were taken at an interval of 30 min up to 300 min. The osmotically pretreated samples were further dried up to its equilibrium moisture content in a tray drier at 60°C and experimental data were fitted successfully using Page and Henderson & Pabis model. The osmo-convective dehydrated samples were evaluated for its quality parameters i.e. color (L, a, b, ∆E, C* and h°), rehydration ratio... |

| The European diesel fuel specification limits the biodiesel content to 7 %. It is, however, desirable to increase the amount of renewables in the transport sector; therefore blending with a higher biogenic fuel content is of interest. Blending of fuels can lead to chemical reactions between fuel components and may result in undesired products. In detail, aged biodiesel from unsaturated FAME and fossil diesel fuels can form oligomers and precipitations with a maximum in the range of B10 to B20. Precursors are oligomers that can be separated from the biodiesel or the blends in an amount of up to 20 %. These oligomers seem to have potency for chemical reactions with fuel components or the engine oil. To prevent tentative problems in the fuel filter, the... |

| The relative abundance of almond seed in several tropical regions of the world coupled with the little knowledge of its utilization in vegetable oil production prompted the need for this review. The aim is to review almond oil expression through different extraction/expression approach, the economic and health benefits of almond oil, and the challenges and prospects of almond oil extraction in Nigeria. This review covers the recent significant materials found in the literature on almond seed and oil extraction/expression. Almond oil is an essential oil packed with a lot of nutrients that are beneficial to human health. Therefore, it is important to devise better approach for maximum oil extraction/ expression. |

| Biomass furnace ash (BFA) generated from drying of grains in mechanical dryers were blended with cement in varying ratio of 1:4, 1:5, 1:6, 1:7 and 1:8 by volume. Each composition was cured in an ambient condition for 7, 14 and 28 days and determined their properties such as density, porosity, compressive strength and thermal shock resistance. Cold crushing strength increased with increasing cement content and curing time. Likewise, density increased with increasing cement content and curing time while porosity showed the other way. All the sample compositions exceeded 30 cycles without any crack when subjected to thermal shock resistant cycles of heating and cooling using a firing temperature of 1000oC in an electric muffle furnace. |
