make sure that the soil is not infested before planting and that the transplants are free of nematodes. The type of cover crop used in peach orchards can have a considerable effect on the degree of attack by root knot nematodes and consequently on the growth and yield of the trees. In experimental plots in Georgia, trees on plots where root knot resistant cover crops were planted produced about...

many of precision farming studies have shown a high plant-to-plant variability for many crops. this study was conducted to evaluate the plant-to-plant variability of three medicinal crops in comparison with corn as a long term commercial species. thus a field experiment was performed in 2009-2010 in ferdowsi university of mashhad, research farm. in this experiment plant morphological characters...

Effect of several soil fumigants on plant-parasitic nematodes, weeds, and snapdragon ( Antirrhinum majus L.) production were evaluated in a commercial site in southeast Florida in 2002-03. Treatments consisted of methyl bromide (98%) + chloropicrin (2%), metam sodium, metam sodium + chloropicrin, and a nontreated control. All fumigant treatments reduced (P < 0.05) weed populations compared to t...

introduction after crops harvesting, conditions and durations of storage are considered as the most crucial factors formaintaining the nutritional value and quality of agro-horticultural products such as tomato (lycopersicom esculentum mill.) and its waste reduction. however, the rhizopus rot (rhizopus stolonifer) and black spot rot (alternaria alternate) are the most important postharvest dise...

Salt stress is a worldwide environmental signal, reducing the growth and yield of crops. To improve crop tolerance to salt, several beneficial microbes are utilized. Here, nitrogen-fixing bacterium Azorhizobium caulinodans root endophytic fungus Piriformospora indica were used inoculate tomato (Solanum lycopersicum) under salt stress, effects co-inoculation investigated. Results showed that A. ...

Higher plants utilize various mechanisms to maintain iron homeostasis. To acquire sparingly soluble iron from the rhizosphere, graminaceous plants synthesize natural iron (III) chelators known as mugineic acid family phytosiderophores (MAs). Recent research has uncovered various genes involved in iron uptake and translocation, as well as factors regulating the expression of these genes, especia...

This study aims to demonstrate the effect of farming technology on introducing medicinal plants (MP) and wild food plants (WFP) into a traditional agricultural system within peri-urban zones. Field investigations and semi-structured focus group interviews conducted in the Buhozi community showed that 27 health and nutrition problems dominated in the community, and could be treated with 86 domes...

Alternate Reality Games (ARGs) are a new genre of transmedia practice where players collaboratively hunt for clues, make sense of disparate information, and solve puzzles to advance an ever-changing narrative that is woven into the fabric of the real world. This paper highlights the potential for ARGs to promote 21 Century literacy skills. We propose a meta-level framework for 21 century litera...

With the global population predicted to grow by at least 25% by the year 2050, the sustainable production of nutritious foods will be necessary for human health and the environment. Iron (Fe) is an essential nutrient for both plants and humans. Fe is poorly soluble, especially at high pH levels, at which it is difficult for living organisms to accumulate sufficient Fe. In plants, Fe deficiency ...

This paper describes a methodology to explore the (future) spatial distribution of biofuel crops in Europe. Two main types of biofuel crops are distinguished: biofuel crops used for the production of biodiesel or bioethanol, and second-generation biofuel crops. A multiscale, multi-model approach is used in which biofuel crops are allocated over the period 2000–2030. The area of biofuel crops at...
