Evaluating the potential for snowmelt phosphorus losses from perennial forage crops

Journal of Environmental Quality, EarlyView.
Abstract In cold regions, there is concern that losses of P with snowmelt runoff following freeze and thaw of vegetation may be greater from perennial forages relative to annual crops. We evaluate the drivers of P losses with snowmelt runoff over a network of field‐scale small watersheds in Manitoba, Canada, following annual crops (59 site‐years ...

Modeling of Winter Hardiness Formation in Winter Wheat Plants [PDF]

Ukrainian Journal of Ecology, 2019
A dynamic model of the formation of winter hardiness of winter wheat plants during the autumn period of vegetation, which describes the growth processes, plant development and the passing of the two phases of the autumnal hardening under the effect of agrometeo-rological conditions in autumn, was developed.

Effect of P rates in long‐term conservation agriculture trials on the vertical distribution of soil acidity and nutrient availability

Journal of Environmental Quality, EarlyView.
Abstract Few studies are published on the long‐term impact of phosphorus (P) rates as triple superphosphate (208 g P kg−1) on the vertical distribution of soil acidity and the availability of macro and micronutrients within conservation systems. This study explores the long‐term impacts of increasing P rates on the vertical distribution of soil acidity

A novel quantitative trait locus for barley yellow dwarf virus resistance and kernel traits on chromosome 2D of a wheat cultivar Jagger

The Plant Genome
Barley yellow dwarf (BYD) is one of the most serious viral diseases in cereal crops worldwide. Identification of quantitative trait loci (QTLs) underlining wheat resistance to barley yellow dwarf virus (BYDV) is essential for breeding BYDV‐tolerant wheat

The key role of local and global farmer networks in the development of conservation agriculture in California

Journal of Environmental Quality, EarlyView.
Abstract This article chronicles the history of California's Conservation Agriculture Systems Innovation (CASI) Center and how it has increased agricultural sustainability in the San Joaquin Valley, a major production area for the United States, by using agroecological practices to reduce soil erosion and conserve soil moisture, champion systems ...

Evaluating a worldwide wheat collection for resistance to Hessian fly biotype ‘Great Plains’

Frontiers in Plant Science
Hessian fly (HF), Mayetiola destructor, is a major insect pest that causes severe losses in grain yield and quality of wheat (Triticum aestivum). Growing resistant cultivars is the most cost-effective approach to minimize wheat yield losses caused by HF.
