Citreoviridin levels in Eupenicillium ochrosalmoneum-infested maize kernels at harvest.
Citreoviridin contents were measured in eight bulk samples of maize kernels collected from eight fields immediately following harvest in southern Georgia. Citreoviridin contamination in six of the bulk samples ranged from 19 to 2,790 micrograms/kg. In hand-picked samples the toxin was concentrated in a few kernels (pick-outs), the contents of which were stained a bright lemon yellow (range, 53,...
متن کاملeffect of planting ratio and harvest time on forage quality of maize in maize-cowpea intercropping
to study the effect of planting rates and harvest time on forage quality of maize in maize-cowpea intercropping, an experiment was conducted at the research farm of zabol university, during 2007 and 2008. the experiment was arranged in a 7×2 factorial one in complete randomized block design with 4 replications. the two factors consisted of seven planting ratios of maize and cowpea (100:100, 100...
متن کاملHarvest and Post-harvest Operations
Harvest and post-harvest operations constitute principal constraints to rice production, especially in irrigated systems, because of the larger yield that has to be handled. Post-harvest crop losses of up to 35% have been reported and attributed to inefficiency of manual threshing of rice by small-scale farmers. This leads to poor grain quality and rejection of locally produced rice. The Africa...
متن کاملMeasurements of Soil Carbon Dioxide Emissions from Two Maize Agroecosystems at Harvest under Different Tillage Conditions
In this study a comparison of the soil CO2 fluxes emitted from two maize (Zea mays L.) fields with the same soil type was performed. Each field was treated with a different tillage technique: conventional tillage (30 cm depth ploughing) and no-tillage. Measurements were performed in the Po Valley (Italy) from September to October 2012, covering both pre- and postharvesting conditions, by means ...
متن کاملOccurrence of Pre- and Post-Harvest Mycotoxins and Other Secondary Metabolites in Danish Maize Silage
Maize silage is a widely used feed product for cattle worldwide, which may be contaminated with mycotoxins, pre- and post-harvest. This concerns both farmers and consumers. To assess the exposure of Danish cattle to mycotoxins from maize silage, 99 samples of whole-crop maize (ensiled and un-ensiled) were analyzed for their contents of 27 mycotoxins and other secondary fungal metabolites by liq...
