Cropping sequences integrating perennial forages and annual crops can generate multidimensional agroeconomic environmental benefits. A 4-yr cropping sequence study was conducted from 2013 to 2016 evaluate the relative merits of various sequences. Three forage seed (creeping red fescue [Festuca rubra L.], alsike clover [Trifolium hybridum pratense L.]) four food (wheat [Triticum aestivum canola ...

DL-beta-aminobutyric acid (BABA) is a non-protein amino acid that is an effective inducer of resistance against a variety of plant pathogens. However, examples of BABA-induced resistance against insect herbivores have not been reported. We applied BABA as a soil drench to legumes and monitored its effects on the pea aphid Acyrthosiphon pisum (Harris). On tic bean (Vicia faba var. minor), BABA i...

agriculture sector has had a significant grow thing role in the iran, but growth and development in this sector is not possible without a suitable risk management. this study has tried to predict and measure the risk from changing weather condition on agriculture products of gorgan county using mont carlo stimulation as one of the powerful tools on risk analysis. the results showed that the hig...

This paper presents the plant genetic resources maintained by Center of Excellence for Legumes Institute Field and Vegetable Crops, National Republic Serbia. The legumes (soybean, alfalfa, red clover, pea vetch) are an invaluable source material a rich divergence development varieties adapted to specific agricultural environmental conditions. Soybean is most important all cultivated occupies la...

to assess required growing degree days (gdd) for phenological stages of four clover species in different planting dates a field experiment was conducted in 2010-11 and 2011-12 cropping seasons in seed and plant improvement institute in karaj, iran. three planting dates (14 september, 28 september and 13 october) and six clover varieties were assigned to main plots and sub-plots, respectively, a...

Growing degree days (GDD) is a tool to predict plant growth and can be adapted for use in any species, including cover crops. A limitation of the GDD calculation accurate temperature parameters used development. For most crop cardinal temperatures are not well defined literature, leading less GDD. The objective this study was determine eight Austrian winter pea (Pisum sativum), balansa clover (...

1 Altered atmospheric composition, associated with climate change, can modify herbivore population dynamics through CO2 and/or O3-mediated changes in plant quality. 2 Although pea aphid Acyrthosiphon pisum genotypes exhibit intraspecific variation in population growth in response to atmospheric composition, the proximate mechanisms underlying this variation are largely unknown. 3 By rearing sin...

A major goal in evolutionary biology is to uncover the genetic basis of adaptation. Divergent selection exerted on ecological traits may result in adaptive population differentiation and reproductive isolation and affect differentially the level of genetic divergence along the genome. Genome-wide scan of large sets of individuals from multiple populations is a powerful approach to identify loci...
