The effect of municipal sewage sludge on the content, use and mass ratios of some elements in spring barley biomass

Soil Science Annual, 2017
Municipal sewage sludge contains considerable amounts of macro and microelements essential for plant nutrition. With decreasing use of natural and organic fertilizers, there is a need to search for alternative sources of organic matter (which is a ...

Nitrogen Fertilizer Application in Grass–Clover Elevated Nitrate Leaching in the Follow‐on Maize Crop

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background: Grass–clover and silage maize are key for dairy feed production and frequently occur within the same crop rotations. Fertilizer management in grass–clover may leave residual effects that influence both environmental outcomes and the performance of subsequent maize crops.

An eQTL analysis of partial resistance to Puccinia hordei in barley [PDF]

, 2010
Background - Genetic resistance to barley leaf rust caused by Puccinia hordei involves both R genes and quantitative trait loci. The R genes provide higher but less durable resistance than the quantitative trait loci. Consequently, exploring quantitative

Food Security Versus Environmental Health: The Nitrogen Dilemma

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Nitrogen is an essential element for plant growth and, consequently, crop production. However, the cycling of nitrogen in the environment can have negative effects. Here, we review the historical development of scientific and public awareness of these effects and the influence this has had on political action to control them.

Weed–Crop Competition: Which plants benefit more from mineral nitrogen?

Weed Technology
A Mineral Ecological Cropping System (MECS) using mineral fertilizers but no synthetic pesticides has been tested in field trials in Germany over six years. Uncertainty persists regarding whether mineral nitrogen (N) favors crops or weeds under MECS, and

Applying nitrogen fertilizers for spring barley

The Journal of Agricultural Science, 1961
1. Fifteen experiments on spring barley (mainly Proctor), done from 1957 to 1959, compared alternative alternative methods of applying 0·3, 0·6 and 0·9 cwt. N/acre.2. Combine-drilling 0·3 or 0·6 cwt. N/acre as ammonium sulphate produced higher mean yields than broadcasting, but drilling 0·9 cwt.

HEDONIC PRICES IN THE MALTING BARLEY MARKET [PDF]

An important characteristic in the malting barley market is the multitude of quality variables which affect the value of particular samples. The purpose of this study was to estimate implicit (or hedonic) prices for selected quality factors.

Mapping adaptation of barley to droughted environments [PDF]

, 2008
Identifying barley genomic regions influencing the response of yield and its components to water deficits will aid in our understanding of the genetics of drought tolerance and the development of more drought tolerant cultivars. We assembled a population

Late Holocene environmental history of Dojran, Macedonia: Investigating the interplay of imperial dynamics and climatic change

Journal of Quaternary Science, EarlyView.
ABSTRACT This study presents a high‐resolution, multi‐proxy reconstruction of environmental and land‐use change from Lake Dojran over historical times (last 2500 years), combining pollen, biomarkers, radiocarbon dating, Ottoman taxation records and other historical data.
