Effects of cover crops on soil CO2 and N2O emissions across topographically diverse agricultural landscapes in corn-soybean-wheat organic transition Eur. J. Agron. (IF 3.726) Pub Date : 2020-10-27 L.T.T. Nguyen; A.N. Kravchenko
Agriculture represents about 10 % of total greenhouse gases (GHG) emission in the US, in which carbon dioxide (CO2) and nitrous oxide (N2O) can greatly contribute to global warming and climate change. Organic farming has been increasingly popular as it provides long-term environmental benefits including GHG mitigation. Judicious use of cover crops in crop rotation systems has been considered an effective

Diagnosis of camelina seed yield and quality across an on-farm experimental network Eur. J. Agron. (IF 3.726) Pub Date : 2020-10-28 Margot Leclère; Anne-Raphaëlle Lorent; Marie-Hélène Jeuffroy; Arnaud Butier; Christophe Chatain; Chantal Loyce
Camelina [Camelina sativa (L.) Crantz] is an emerging oilseed crop combining both industrial and agronomic advantages. Camelina seed yield, oil and protein contents, and fatty-acid composition, vary across genotypes, environments, and agricultural practices. However, no studies have been conducted to identify and rank major limiting factors explaining yield and quality variations under on-farm conditions

Yield and development of winter wheat (Triticum aestivum L.) and spring barley (Hordeum vulgare) in field experiments with variable weather and drainage conditions Eur. J. Agron. (IF 3.726) Pub Date : 2020-10-16 Kasper Jakob Steensgaard Jensen; Søren Hansen; Merete Elisabeth Styczen; Maja Holbak; Signe Marie Jensen; Carsten Tilbæk Petersen
The benefits of drainage with respect to improving yield level and stability was recognized millennia ago, hence drainage is an old agronomical practice. However, agriculture is under constant change, and few long-term field studies exploring the need for drainage have been conducted in modern north European agricultural systems. The objective of this study is to describe yield variations in modern

An innovated crop management scheme for perennial rice cropping system and its impacts on sustainable rice production Eur. J. Agron. (IF 3.726) Pub Date : 2020-10-16 Yujiao Zhang; Guangfu Huang; Shilai Zhang; Jing Zhang; Shuxian Gan; Mao Cheng; Jian Hu; Liyu Huang; Fengyi Hu
Perennial grain has been proposed to provide an effective means of ensuring both food and ecological security. The newly released cultivar of perennial rice 23 (PR23) represents a new rice production system that is based on no-tillage. Nevertheless, how perennial rice responds to this new system remains unclear. Two field experiments were conducted over four successive seasons from 2016 to 2017 in

Legacy effects of soil fertility management on cereal dry matter and nitrogen grain yield of organic arable cropping systems Eur. J. Agron. (IF 3.726) Pub Date : 2020-10-14 Johannes Wilhelmus Maria Pullens; Peter Sørensen; Bo Melander; Jørgen Eivind Olesen
The yields of crops in organic farming are typically lower than in conventional farming, although this depend greatly on local climatic conditions and on crop and soil management. A long-term study over three consecutive 4-year cropping cycles at three locations in Denmark compared organic arable cropping systems varying in fertilization management (green manure crops, cover crops, livestock manure)

Relative abundance of ureides differs among plant fractions in soybean Eur. J. Agron. (IF 3.726) Pub Date : 2020-10-09 Luiz H. Moro Rosso; Santiago Tamagno; Anelise L. da Silva; Adalgisa R. Torres; Raí A. Schwalbert; Ignacio A. Ciampitti
The present study aims to compare the relative abundance of ureides (RAU) among soybean [Glycine max (L.) Merr.] plant fractions in contrasting trial settings and under three nitrogen (N) rates, designed to create variability on symbiotic N fixation. A greenhouse and a field experiment evaluated the RAU in plant fractions (base of the main stem, petiole and leaflets of the uppermost fully developed
