Presented are the results of a 13-week rat feeding study with grain from MON 88017 corn (brand name YieldGard VT Rootworm/RR2), protected from feeding damage caused by corn rootworm and tolerant to glyphosate, the active ingredient in Roundup agricultural herbicides. Corn rootworm protection is accomplished through the introduction of cryBb1 coding sequence from Bacillus thuringiensis into the ...

Under the guidance of the agricultural system theory, operational research theory and decision-making support system theory, the regional agricultural development decision support system (RADDSS) was developed in this study ,in which different analysis method and models was integrated. By providing data, right models and analysis methods, RADDSS can assist decision-makers and administrators to ...

Agricultural productivity has increased in Argentina, with cereals yield going from 1.4 to 4.8 tonnes grain ha-1 during the period 1961-2014 [6]. However, in the Province of Buenos Aires, cereals production has changed its composition during the period 2006 2016, with wheat production decreasing from approx.9 mill. to 5 mill. of tonnes and corn production going from 6.1 to 10. 1 mill. tonnes [7...

Pulmonary aspergillosis may occur either as a primary or secondary infection. Primary infection is rare and occurs in people dealing with grain contaminated by fungus, e.g. agricultural workers, and in people handling pigeons and parrots. Secondary infection may occur as a superimposed infection on the abnormal pulmonary condition, e.g. bronchial carcinoma, pneumoconiosis, tuberculosis or bronc...

Since late 2006, biofuel policies have caused high grain/oilseed prices by creating a link between crop and biofuel policies. The value of agricultural trade has increased sharply, mostly because of high prices, not increased trade volume. Biofuel policies have little to do with the agenda of the Doha trade negotiations but have had indirect effects in that production subsidies and import barri...

Right now it is not clear how other cost and benefit factors such as production economics, sustainability and carbon sequestration, and grain quality will be taken into account in the development of the criteria. Because of current water use impairments, and the expectation that the criteria, when developed and implemented, will add to the list of impairments, there is an immediate and continui...

INTRODUCTION The grain industry (mainly maize and wheat) is the largest crop industry in South Africa under rain-fed conditions. Significant changes have taken place since deregulation in agriculture and the termination of subsidies from mid 1990s. The total area under grain has decreased by about 10% to 15% (C. Du Plessis, pers. commun. 2001) due to lower prices (based on import parity and fre...
