In Washington, over fifty percent of the wheat produced under rainfed conditions receives less than 300 mm of annual precipitation. Hence, a winter wheat-summer fallow cropping system has been adopted to obtain adequate moisture for winter wheat production. Current tilled fallow systems are exposed to significant soil degradation from wind and water erosion. As a result, late-planted no-till fa...
The use of low air temperatures (79 to 93 °F) and relative humidities (19% to 68%) to dry thin-layer samples of rough rice to the desired 12.5% moisture content was investigated. Drying rates and durations and their effects on the quality parameters of head rice yield, color, and pasting viscosity of longand medium-grain rice cultivars harvested at 19.6% and 17.5% moisture contents, respectivel...
Interest in using hermetic technologies as a pest management solution for stored grain has risen in recent years. One hermetic approach, Purdue Improved Crop Storage (PICS) bags, has proven successful in controlling the postharvest pests of cowpea. This success encouraged farmers to use of PICS bags for storing other crops including maize. To assess whether maize can be safely stored in PICS ba...
The assessment of soil moisture content and surface roughness from remotely sensed data is of primary importance for improving agricultural techniques of conservation farming such as yield forecasts, scheduling irrigations, fertilization. SAR (Synthetic Aperture Radar) remotely sensed data may provide a powerful tool for indirectly retrieving these agricultural surface parameters over large are...
Drying: moisture measurement at the end of drying is essential to follow up drying course and to decide whether it is achieved or not. On one hand, too long a drying course may have bad consequences for quality and food safety because of unexpected fermentations and mould growth. On the other hand, the next step in the process is storage. Also, drying to a too low moisture content can result in...
The problem of grain preservation is extremely relevant today. Due to the increase in population, task ensuring food security arises, based on production and rational storage grain, since a large number agricultural products are stored without provision necessary conditions. quality maintained compliance with rules, it becomes available throughout year. method varies temperature humidity. Stora...
The many factors that determine the price and suitability for processing of cereal grain can be divided into two groups: seasonal factors and inherited factors. Seasonal factors are largely determined by growing, harvesting, and storage conditions. These aspects of quality are readily tested and include moisture content, test weight, soundness of the grain, and the presence of contaminants. On ...
Abstract This research was conducted in Toroq Experimental field station, Mashhad, Iran, for two successive cropping seasons (2000-2002), using split plot experimental design based on complete randomized blocks with three replications. Moisture stress treatments (at seven levels) were assigned to main plots, including: D1 ( full irrigation), D2 (no irrigation from one-leaf to double ridge) st...
In most wheat growing moderate regions and especially in the north of Iran climate, is affected grain filling by several physical and abiotic stresses. In this region, grain filling often occurs when temperatures are increasing and moisture supply is decreasing. The experiment was designed in RCBD with split plot arrangements with four replications. Four irrigation treatments included (I0) no i...
Optimization of the cereals drying operation requires a model containing the operating variables for dryers. Modeling of grain dryer is still uncertain since the drying process is unpredictable and relies on empirical parameters. The paper present the main mathematical models proposed in the last years for describing the drying phenomena. The main objective is to develop a model that would desc...
