In order to identify miscellaneous seed from maize seed accurately and rapidly, maize seed purity identification method based on color extracted from the images of both the maize crown and the maize side was proposed for improving maize seed purity. Firstly, segmentation and single extraction were carried on the original image; secondly, the color models RGB and HSV were used to extract multidi...

The methane potential of nine varieties of fresh maize harvested at three different times and of maize silage was experimentally determined in batch assays. The ultimate methane productivity in terms of volatile solids (VS) was determined as 213.94-313.63, 195.88-334.81 mL/g VS from several fresh and silage maize in three stages, respectively. The average specific methane yield of wax ripeness ...

new sources of maize resistance to the maize weevil, sitophilus zeamais infestation are indispensable in successful breeding programs against post harvest grain damage. the study investigated the characters and mechanisms that confer resistance to weevil infestation using twenty elite maize genotypes. detailed morphological and physical studies were conducted on whole-maize grain. the grain hul...

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 ...

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...

Abstract Yield is a function of environmental quality and the sensitivity with which genotypes react to that. Environmental characterized by meteorological data, soil agronomic management, whereas genotypic embodied combinations physiological traits that determine crop capture partitioning resources over time. This paper illustrates how genotype responses can be studied combination simulation s...

Floods and droughts are the events that most threaten crop production; however, impact of floods on crops is still not fully understood often under-reported. Nowadays, multiple sources information approaches support estimation agricultural losses due to floods. This study aims understand differences in loss estimates provided by two conceptually different (crop models expert-based models), eval...

Crop models are ideally suited to quantify existing climatic risks. However, they require historic climate data as input. While daily temperature and rainfall data are often available, the lack of observed solar radiation (Rs) data severely limits sitespecific crop modelling. The objective of this study was to estimate Rs based on air temperature solar radiation models and to quantify the propa...
