Wang, Q., Y. Li, Z. Handoo, and W. Klassen. 2007. Influence of cover crops on populations of soil nematodes. Nematropica 37:79-92. A pot experiment was carried out in south Florida to elucidate suppressive or antagonistic effects of several cover crops grown in rotation on soil nematode populations. The crops were two marigolds, Tagetes patula L. ‘Dwarf Double French Mix’ (MDF), and Tagetes pat...

To date, regional surveys assessing the risk of transgene escape from GM crops have focused on records of spontaneous hybridization to infer the likelihood of crop transgene escape. However, reliable observations of spontaneous hybridization are lacking for most floras, particularly outside Europe. Here, we argue that evidence of interspecific reproductive compatibility derived from experimenta...

Research methods that predict Fe bioavailability for humans can be extremely useful in evaluating food fortification strategies, developing Fe-biofortified enhanced staple food crops and assessing the Fe bioavailability of meal plans that include such crops. In this review, research from four recent poultry (Gallus gallus) feeding trials coupled with in vitro analyses of Fe-biofortified crops w...

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...

Modern agriculture favours the selection and spread of novel plant diseases. Furthermore, crop genetic resistance against pathogens is often rendered ineffective within a few years of its commercial deployment. Leptosphaeria maculans, the cause of phoma stem canker of oilseed rape, develops gene-for-gene interactions with its host plant, and has a high evolutionary potential to render ineffecti...

Crops are harvested by performing a series of operations with harvesting vehicles in the field. The harvest operation is performed with combines (harvesters). Supporting logistical activities of transferring and transporting harvest (grain) from the field to the farm are carried out with the help of tractors. This research focuses on detailed logistics planning of various infield harvest operat...

Remote sensing bears the potential to provide quantitative information of agricultural crops instantaneously and of a certain regional extent. Estimates of crop growth which are used for crop yield prediction, and timing of forthcoming harvest are important in agricultural planning and policy making. For non-optimal growing conditions, estimates of crop growth may be inaccurate. Crop monitoring...

Emissivity measurements were made during the ReSeDA experiment. Emissivities are necessary for obtaining surface temperatures from remote sensing data in the thermal infrared, and they enter the radiative balance in the atmosphere-surface system. The objective of this study was to assess the spatial variation of surface emissivity in the area, with special regard to the spectral variation of em...
