in order to study the intercropping effects of maize (zea mays l.) and bean (phaseolus vulgaris l.) and evaluating effect of intercropping on weed biomass, a field experiment was conducted at the agricultural research station, payamenoor university of nagadeh,west- azarbayjan, iran during growing season of 2009-2010. the experiment was laid out as randomized complete block design with three rep...

This experiment aimed to quantify the methane emissions and intake, digestibility, performance, and carcass characteristics of finishing beef cattle offered maize (Zea mays) silages harvested at 1 of 4 sequential stages of maturity and to relate these values to those obtained from animals offered an ad libitum concentrate-based diet. Sixty continental crossbred steers with a mean initial BW of ...

Maize (Zea mays), also called corn, is believed to have originated in central Mexico 7000 years ago from a wild grass, and Native Americans transformed maize into a better source of food. Maize contains approximately 72% starch, 10% protein, and 4% fat, supplying an energy density of 365 Kcal/100 g and is grown throughout the world, with the United States, China, and Brazil being the top three ...

HMN-176 ((E)-4-[[2-N-[4-methoxybenzenesulfonyl]amino]stilbazole]1-oxide) is an active metabolite of HMN-214 ((E)-4-[2-[2-(N-acetyl-N-[4-methoxybenzenesulfonyl]amino)stilbazole]]1-oxide), which has a potent antitumor activity in mouse xenograft models. In this study, we show that HMN-176 circumvents multidrug resistance in a K2 human ovarian cancer subline selected for Adriamycin resistance (K2/...

In this study, we show that HMN-176 circumvents multidrug resistance in a K2 human ovarian cancer subline selected for Adriamycin resistance (K2/AR...

Mixed cropping is practised widely in developing countries and is gaining increasing interest for sustainable agriculture in developed countries. Plants in intercrops grow differently from plants in single crops, due to interspecific plant interactions, but adaptive plant morphological responses to competition in mixed stands have not been studied in detail. Here the maize (Zea mays) response t...

Low soil fertility and high weed infestation are the main culprits for the declining maize production inWestern Kenya. Technology packages to address these constraints exist, but their effectiveness is likely to be influenced by variability in soil types and farm management practices in the region. Trials were conducted during the 2008/2009 cropping seasons to investigate the nutrient use e...

Water use efficiency (WUE) reflects the coupling of the carbon and water cycles and is an effective integral trait for assessing the responses of vegetated ecosystems to climate change. In this study, field experiments were performed to examine leaf WUE (WUEleaf) in response to changes in CO2 concentration and other environmental variables, including soil moisture and air temperature. We al...

The C(4)-Pdk gene encoding the C(4) enzyme pyruvate, orthophosphate dikinase (PPDK) of maize (Zea mays cv Golden Cross Bantam) was introduced into the C(3) plant, rice (Oryza sativa cv Kitaake). When the intact maize C(4)-Pdk gene, containing its own promoter and terminator sequences and exon/intron structure, was introduced, the PPDK activity in the leaves of some transgenic lines was greatly ...
