Concentric Ag Inc. (Concentric) is a Canadian company specializing in the development of sustainable**plant-microbial agricultural products. Healthy soils include proliferating communities of plant**growth-promoting bacteria which contribute to higher crop yields. Therefore, enriching soils with the beneficial**bacterial communities and treating plants with biostimulants represent products provided by Concentric. The**company's main product, IN-M1 is registered in Canada and 20 US states for row crops. Concentric's goal is**not simply to improve field crop yields in Canada with its proprietary products, but also develop proper**methodology to help farmers achieve higher yields with a lesser nitrogen and phosphorus input to reduce input**costs and environmental footprint. In this project, the company is aiming to evaluate the potential growth- and**yield-promotive capabilities of IN-M1 product co-applied with nitrogen and phosphorus on green pepper**plants. Since bacterial-based biostimulants improve plant growth and yield in part by increasing mineral**assimilation and thus photosynthesis, the IN-M1 product will be tested at three doses with either typical or**reduced nitrogen and phosphorus nutrition. The IN-M1-mediated increase in nitrogen and phosphorus**assimilation, and photosynthesis, may also lead to a decreased input of nitrogen and phosphorus, which not**only will reduce input costs of Canadian farmers, but also decrease environmental damage. Furthermore, the**company expects that the proposed research will provide a blueprint information that can then be used to alter**the design of their bacterial biostimulants to improve the yield of green pepper and other field dicot crops that**will have the potential to benefit Canadian agriculture.

同心公司是一家加拿大公司，专门从事可持续**植物微生物农产品的开发。健康的土壤包括促进植物生长的细菌群落，它们有助于提高作物产量。因此，用有益的细菌群落丰富土壤和用生物刺激剂处理植物是同心公司提供的产品。该公司的主要产品IN-M1在加拿大和美国20个州注册种植行作物。同心公司的目标不仅是**用其专利产品提高加拿大的大田作物产量，还**开发适当的**方法，帮助农民在较少的氮和磷投入的情况下实现更高的产量，以减少投入**成本和环境足迹。在这个项目中，该公司的目标是评估IN-M1产品与氮和磷配合使用在青椒**植物上的潜在生长和增产能力。由于以细菌为基础的生物刺激剂部分通过增加矿物质同化从而促进光合作用来改善植物的生长和产量，因此IN-M1产品将在典型或**氮磷营养减少的情况下进行三次剂量的测试。IN-M1介导的氮磷同化和光合作用的增加也可能导致氮磷投入的减少，这不仅会降低加拿大农民的投入成本，而且还会减少对环境的破坏。此外，该公司预计，拟议的研究将提供一个蓝图信息，然后可以用来改变他们的细菌生物刺激剂的设计，以提高青椒和其他田间双子叶作物的产量，这些作物**将有可能使加拿大农业受益。
