Effects of cover crop, N and residue management on the financial sustainability of processing tomatoes in Southwestern Ontario

Abstract Given the potential environmental and economic sustainability consequences of cover crop adoption, N fertilizer application, residue management, this study focuses on yield financial effects these processing tomato production in Ontario, Canada. The employs modeling using field data from a long-term experiment (oat, cereal rye, radish, radish-rye mixture) 2010 to 2020. Averaged over six experimental years, compared no (87 Mg ha −1 ) radish (99.6 mix (95.2 crops produce statistically significantly higher yields as isolated practices, increasing farm net returns by $1120 $604 , respectively. When combined with rye application additionally results than base practice crop, zero retained residue. Oat does not appear have significant effect dataset. yield, $882 while management not.
