Genetically modified (GM) maize expressing the Bt-toxin Cry1Ab (Bt-maize) was tested for effects on survival, growth, and reproduction of the water flea Daphnia magna, a crustacean arthropod commonly used as a model organism in ecotoxicological studies. In three repeated experiments, D. magna were fed 100% ground maize in suspension, using either GM or isogenic unmodified (UM) maize. D. magna f...

In this paper,according to the characteristics of maize disease knowledge,OWL DL language was used to build maize diseases ontology, and the reasoning rule of maize diseases was defined by using the expressive ability of SWRL rule language.The author introduced several realizable reasoning functions,and achieved the diagnostic reasoning of maize disease knowledge by Jess inference engine.The re...

genetically modified (gm) foods hold the key to ending hunger and malnutrition in africa.   due to the increasing number of gmos cultivation and delay in the approval of biosafety law in nigeria, it has become necessary to screen maize products in order to determine the identity of the consumed daily foodstuffs. in this study, dna extraction from raw and processed maize foods sold commercially ...

A 2-yr field experiment was conducted to determine the effects on Diabrotica spp. (Coleoptera: Chrysomelidae) of an insecticidal seed treatment (Poncho 1250, (AI)/clothianidin) and a granular insecticide (Aztec 2.1G, (AI)/tebupirimphos and cyfluthrin) alone and in combination with maize producing the insectidical toxin Cry3Bb1 derived from the bacterium Bacillus thuringiensis (Bt). Yields for B...

Possible non-target effect of transgenic cry1Ie maize exerts on natural enemy community biodiversity in the field is unresolved. In the present study, a 2-yr comparison of transgenic cry1Ie maize (Event IE09S034, Bt maize) and its near isoline (Zong 31, non-Bt maize) on natural enemy community biodiversity were compared with whole plant inspections, pitfall traps and suction sampler. Natural en...

Bt maize technology involves developing hybrid maize crops that incorporate genes developed from the soil dwelling bacteria Bacillus thuringiensis (Bt). The primary benefit of Bt maize technology is the heightened crop protection from stem borers, which are maize pests that can inflict serious crop losses. Bt maize has been grown in Mexico, South Africa and several countries in the EU, with mor...

in order to evaluation the different sowing date and different harvest time in intercropping of maize and legume plants on maize forage quality, a randomized complete block with three replications conducted in research field of university of sari agricultural sciences and natural resources in 2011. treatments were included three legume plants (soybean, fenugreek and cowpea) at two sowing time (...

In the conventional maize wet-milling process, a maize kernel is separated into its individual components. Starch (which constitutes 60–70% of the maize kernel) is the prime product. Other components of the maize kernel, which includes germ (oil), protein and the fiber, are recovered as coproducts. Presently, maize fiber is mixed with heavy steepwater and sometimes with germ meal to produce mai...

The study assessed economic of maize production in Ogori/Magongo local government area of Kogi State. To this end, effort was made to examine the socio economic characteristics of the maize farmers, determine the resource use efficiency, problems as well as profitability of maize production in the area. To achieve the objectives of this study 48 maize farmers where randomly selected from 5 ward...
