Abstract

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

覆盖作物、氮和残留物管理对安大略省西南部加工番茄财务可持续性的影响

摘要考虑到覆盖作物的采用、氮肥施用和残留物管理对环境和经济可持续性的潜在影响，本研究重点关注这些对加拿大安大略省加工番茄生产的产量和财务影响。该研究使用了2010年至2020年长期覆盖作物试验（燕麦、谷类黑麦、萝卜和萝卜-黑麦混合物）的田间数据进行财务建模。在六个实验年的平均值中，与无覆盖（87 Mg ha−1）相比，萝卜（99.6 Mg ha–1）和萝卜-黑麦混合作物（95.2 Mg ha‑1）的覆盖作物在统计上显著提高了番茄产量，使农场净收益分别增加了1120 ha−和604 ha−1美元。当与施氮相结合时，黑麦施用还导致番茄产量在统计上显著高于无覆盖作物、零施氮和残留的基本做法。在该数据集中，燕麦覆盖似乎对番茄产量没有统计学上的显著影响。施用氮肥在统计上显著提高了番茄产量，净收益增加了882公顷-1，而残留物管理则没有。

期刊介绍： Renewable Agriculture and Food Systems (formerly American Journal of Alternative Agriculture) is a multi-disciplinary journal which focuses on the science that underpins economically, environmentally, and socially sustainable approaches to agriculture and food production. The journal publishes original research and review articles on the economic, ecological, and environmental impacts of agriculture; the effective use of renewable resources and biodiversity in agro-ecosystems; and the technological and sociological implications of sustainable food systems. It also contains a discussion forum, which presents lively discussions on new and provocative topics.
