Nitrogen (N) is essential to crop yield improvement and it can change crops' ability to defend against herbivores. To maximize economic yield, a higher amount of N‐fertilizer is often applied than the minimum required. Azotobacter is a good alternative to reduce N fertilizer application. In this study, we studied the yield and secondary defensive chemicals of maize, as well as the response of the key maize insect pest, Mythimna separata, as fed on maize plants inoculated with Azotobacter chroococcum and cultivated at different N fertilizer rates (i.e. the control rate of nitrogen fertilizer (CR), 80%CR and 60%CR) from 2018 to 2019.

即使在减少氮肥施用的情况下，接种球孢固氮菌也可以改善玉米的生长和玉米对粘虫，分离的Mythimna separata的抗性。

氮（N）对于提高作物产量至关重要，它可以改变作物防御草食动物的能力。为了最大程度地提高经济产量，通常会使用比最低量更多的氮肥。固氮菌是减少氮肥施用的好选择。在这项研究中，我们研究了玉米接种玉米绿单孢菌并以不同氮肥用量（即对照）种植后，对玉米的产量和次要防御性化学物质以及主要玉米害虫Mythimna separata的反应。从2018年到2019年氮肥（CR），80％CR和60％CR的比率）。
