Assessing benefits of land use intensification on extensive grain cropping systems of the Pampas Eur. J. Agron. (IF 5.124) Pub Date : 2022-02-28 José F. Andrade, Matías Ermacora, Emilio H. Satorre
A holistic approach in the design of cropping systems is essential to boost productivity in a sustainable manner. One of the most important decisions in the cropping system is the way that crops are organized in sequences, which is commonly oriented to obtain high yields and associated economic return while minimizing variability and risk. Increased cropping intensity based on sequenced winter/summer

Feasibility of early fertilization of maize with 15 N application to preceding cover crop Eur. J. Agron. (IF 5.124) Pub Date : 2022-02-23 Letusa Momesso, Carlos Alexandre Costa Crusciol, Carlos Antonio Costa do Nascimento, Rogério P. Soratto, Lucas Pecci Canisares, Luiz Gustavo Moretti, Ciro Antonio Rosolem, Paulo Cesar Ocheuze Trivelin, Eiko Eurya Kuramae, Heitor Cantarella
Early nitrogen (N) application on live cover crops or their residues is a potential alternative for supplying N demand while enhancing the yield of subsequent cash crops in tropical regions. The objective of applying N on live forage grasses or their residues to no-till (NT) systems is to promote the gradual release of N via straw decomposition to the subsequent crop. However, the N use efficiency

Maize yield in response to alternating low- and high-density rows of diverse hybrids Eur. J. Agron. (IF 5.124) Pub Date : 2022-02-23 Amanda B. Burton, Armen R. Kemanian
Production of rainfed summer crops like maize (Zea mays L.) must adapt to a changing climate and retain high productivity. Using diverse hybrids in the same stand is a simple way to adapt to unpredictable stresses during the growing season. However, some hybrids are available at a price premium and therefore their use needs to be cleverly incorporated in the system to balance cost and economic return

Determination of nitrogen dilution curves of corn, canola, and spring wheat in Canada using classical and Bayesian approaches Eur. J. Agron. (IF 5.124) Pub Date : 2022-02-16 G. Jégo, J. Sansoulet, E. Pattey, N. Beaudoin, G. Bélanger, N. Ziadi, N. Tremblay, C. Grant, G. Tremblay, J. O’Donovan, K.N. Harker, R. Blackshaw, E. Johnson, E. Justes
Determining the dynamics of crop nitrogen (N) uptake is essential to optimize N management and increase the sustainability of crop production. The concept of critical N concentration helps to achieve this goal by defining the minimum shoot N concentration required to produce the maximum aerial biomass at a given time during the crop cycle. The objective of this study was to determine new critical N

Future projections of rice exposure to cold stress in China throughout the 21st century Eur. J. Agron. (IF 5.124) Pub Date : 2022-02-14 Pin Wang, Haijian Liu, Wenyuan Wu, Feng Kong, Tangao Hu
Rice exposure to cold stress will be alleviated by the decrease of cold extremes under climate change. The disappearance time of cold exposure and its response to different potential scenes in the 21st century, should be particularly important to make long-term adaptations in China. Given these issues unresolved, here we assessed the decadal changes of rice exposure to cold stress in China throughout
