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...

This study was conducted to determine the potential evapotranspiration (PET) of maize, the crop coefficient (Kc) under full water requirement as well as the cause of decrease in maize yield. It was determined that the seasonal PET of maize is about 486.6 mm. The Kc under full water supply was found to be: 0.11, 0.35, 1.51 and 0.34 for initial, development, midseason and the late season stages r...

Biolistic gun-mediated transformation is one of the two most effective and popular methods for introducing genes into maize. In this chapter, we describe a detailed protocol for genetic transformation of the maize genotype, Hi II. The protocol uses 0.6-microm gold particles as microcarriers and the herbicide resistance bar gene as a selective marker. Both immature zygotic embryos and immature e...

in order to study the sowing system, row distance and weeding effect on yield and yield components of intercropped maize with peanut, this experiment was conducted, as factorial based on a rcbd with three replications at the research farm of agriculture center of zabol university (iran) during growing season 2011- 2012. sowing system were four levels including sole maize, sole peanut, 50% maize...
