Wheat harvesting

Study 1. Wheat ( McNair 1813 ) was planted at the Central Crops Research Station near Clayton (Lynchburg sandy loam) and the Tidewater Research Station near Plymouth (Bayboro loam), North Carolina, at a rate of 101 kg/ha in October of 1980. The following spring or early summer, plots were set up in which a green wheat cover crop or wheat straw and stubble remaining after wheat harvest was (1) left... 

In addition to the tension created by convincing consumers that no food is riskfree, there is tension around food. One reason is because there is a vast separation between the food consumer and the producer. There has been a tremendous decrease in the number of people in industrialized countries who have any connection with farming and food production. The childhood story where the little red hen grows the wheat, harvests and mills the wheat, and bakes the bread is the closest that most... 

Fatty acid determinations The relative amounts of individual hydrolyzable fatty acids in 100 mg samples of freeze-dried tobacco stalk harvested 7 weeks after transplant and in wheat harvested at the 40- to 50-cm height plant stage were determined as fatty acid methyl esters by GC-FID (17). 

The synthetic auxin analogues have a much stronger effect on broadleaved plants than on grasses, which gives a high degree of valuable selectivity, but made them useless for their intended application to destroy the wheat harvest in Germany. 

The first crop in North America to be surveyed for vomitoxin was the 1980 wheat from eastern Canada (1). Soft winter wheat harvested in Ontario was noticed to contain pink kernels this is one of the signs that the Fusarium mold which produces vomitoxin causes when it invades the kernels. Forty-four of 45 samples analyzed contained vomitoxin in concentration ranging from 0.01 to 4.3 parts per million (ppm). In Quebec, the contamination was worse. One hundred per cent contamination of the hard spring wheat crop was found based on analyses of 27 samples. Eighty five per cent of the samples contained greater than 0.3 ppm.

Water-autoclave extractions were also much more efficient than neutral EDTA extractions in recovering sorbed/fixed phenolic acids from plant tissues/residues (Blum et al. 1992). For example HPLC analysis of EDTA extracts for wheat stubble collected after a wheat harvest contained no detectable phenolic acid peaks. Water-autoclave extracts of this wheat stubble had 11 distinct peaks. Concentrations for ferulic acid, vanillic acid, p-coumaric acid, and p-hydroxybenzoic acid were 33, 22, 1034, and 47 p,g/g dry weight, respectively (Fig. 3.8). On the other hand water and... 

In experiments with ear treatment crops have been chosen as material, which are widely in Northern Caucasus for production and selection. The tested samples included winter wheat harvested in 2009 (cultivars Ivina, Vassa, Bat ko, Don 107, Kollega, Kalym), winter wheat - cultivar Bastion, destined for Northern Caucasian Region, and selection samples of several millet species, introduced to North Ossetia Japanese millet Echinochloa frumentacea), panic Setaria italica Panicumitalicum) and Italian millet Setaria italica). All millet samples were harvested in 2010.
