Sources of nitrogen for winter wheat in organic cropping systems [PDF]

, 2013
In organic cropping systems, legumes, cover crops, residue incorporation, and manure application are used to maintain soil fertility, but the contributions of these management practices to soil nitrogen (N) supply remain obscure.

Soil health and community well‐being: A framework of intangible outcomes of sustainable agriculture

Journal of Environmental Quality, EarlyView.
Abstract Social outcomes of agricultural practice adoption are often excluded from adoption studies, particularly outcomes related to community well‐being. In large part, this is because assessing the social well‐being outcomes of sustainable agricultural practices lacks a widely accepted framework.

Characterization of a new Lr52 allele for leaf rust resistance in the Iranian wheat landrace PI 622111

The Plant Genome
Leaf rust, caused by Puccinia triticina (Pt), poses a constant threat to global wheat production, and novel leaf rust resistance genes are needed to combat the disease.

The Effects of Topdressing Organic Nitrogen on Hard Red Winter Wheat [PDF]

, 2012
The demand for local organic food is steadily increasing throughout Vermont and New England. Consumers are asking for bread baked with locally grown wheat; however, bakers have been slow to incorporate local wheat flour because of the challenges ...

Greenhouse gas emissions altered by the introduction of a year‐long fallow to continuous rice systems

Journal of Environmental Quality, EarlyView.
Abstract Rice (Oryza sativa L.) production in California follows a norm of mono‐cropping with little to no rotations or fallows. Both winter droughts, which lead to water restrictions, and spring rains, which inhibit field machinery operations, have resulted in increased fallow frequencies, where no crop is grown during the summer growing season.

The efficiency of a durum wheat-winter pea intercrop to improve yield and wheat grain protein concentration depends on N availability during early growth [PDF]

, 2010
Grain protein concentration of durum wheat is often too low, particularly in low-N-input systems. The aim of our study was to test whether a durum wheat - winter pea intercrop can improve relative yield and durum wheat grain protein concentration in low ...

Are historical trends in weather consistent with model predictions in the Central United States?

Journal of Environmental Quality, EarlyView.
Abstract Model projections predict increasing temperatures and precipitation change in many locations in the Central United States. To provide perspective on what these trends might bring relative to what has already happened, we compared historical temperature and precipitation change with what models from the Coupled Model Intercomparison Project ...

THE EFFECT OF THE PREPARATION ‘AGRIMITIN’ ON WINTER WHEAT PRODUCTIVITY AND GRAIN QUALITY IN THE SOUTHERN PART OF THE ROSTOV REGION

Зерновое хозяйство России, 2019
The use of biological stimulants promotes plant metabolism, which improves the utilization of mineral fertilizers and plant defense mechanisms against the effect of unfavorable factors. The paper discusses the results of winter wheat seed treatment with ‘

Agroecological Advantages of Early-Sown Winter Wheat in Semi-Arid Environments: A Comparative Case Study From Southern Australia and Pacific Northwest United States

Frontiers in Plant Science, 2020
Wheat (Triticum aestivum L.) is the most widely-grown crop in the Mediterranean semi-arid (150–400 mm) cropping zones of both southern Australia and the inland Pacific Northwest (PNW) of the United States of America (United States).
