Economic analysis of organic cropping systems under different tillage intensities and crop rotations
Autor: Prabhath Lokuruge, Michael P. Schellenberg, Myriam R. Fernandez, Robert P. Zentner, Buwani Dayananda
Publikováno v: Renewable Agriculture and Food Systems. 36:509-516
Costs of production and organic price premiums are defining factors influencing the economic viability of organic crop production systems. Different agronomic practices, such as crop rotation and tillage intensity, are known to affect the economic pe

Long‐Term Crop Rotation Effects on Production, Grain Quality, Profitability, and Risk in the Northern Great Plains
Autor: Robert P. Zentner, Kelsey Brandt, Reynald Lemke, Elwin G. Smith, C. A. Campbell
Publikováno v: Agronomy Journal. 109:957-967
Crop production in the semiarid Northern Great Plains has historically been limited to wheat (Triticum aestivum L.), with fallow every second or third year. In response to current prices and new production technologies, these cropping systems have be

Long-term weed dynamics and crop yields under diverse crop rotations in organic and conventional cropping systems in the Canadian prairies
Autor: Bruce D. Gossen, Craig Stevenson, Owen Olfert, Reynold Lemke, S. A. Brandt, Eric N. Johnson, Dilshan Benaragama, Allen Moulin, Julia Y. Leeson, Steven J. Shirtliffe, Robert P. Zentner
Publikováno v: Field Crops Research. 196:357-367
Alternative cropping systems are gaining attention throughout the world in order to increase the sustainability of agro-ecosystems. On the Canadian prairies, the tillage-based crop-fallow system has been replaced by no-till reduced input systems or t
