It has been estimated that the world will need to produce >50% more food to feed 9 billion people by the year 2050. If we consider that climate change threatens to reduce crop yields by 25%, the need for improved crop performance has never been greater. The proposed Engage grant will foster collaborative research undertaken by my research group at the University of Manitoba and Stoller Enterprises Ltd (Regina, Saskatchewan). Stoller has a number of products currently on the market that increase crop yield. We have discovered a bacterium (Pseudomonas chlororaphis PA23) that when applied to plants, results in early seedling emergence and increased plant size. Several questions will be addressed in the current proposal including how to best apply the bacteria to the plants. Seed dip, root dip, and drench irrigation will be tested to see how each affects the ability of this bacterium to promote growth. We will determine whether the bacterial cells themselves or specific products they release cause the plant growth promotion effect. Finally, we will investigate how best to store the bacteria so that maximal benefits can be achieved. Our plant-growth promoting bacterium will nicely complement Stoller's existing array of crop-enhancing products, providing economic benefit to the company. Furthermore, soil additives make it possible to dramatically improve crop yields, not only in Canada but across the globe. Boosting plant productivity and vigor through plant-growth promoting bacteria avoids the environmental damage associated with excess chemical run off. Our approach of using beneficial bacteria in place of chemical fertilizers will provide huge benefits to the Canadian agricultural sector and society as a whole.

据估计，到2020年，世界将需要生产超过50%的粮食来养活90亿人。 2050.如果我们考虑到气候变化可能使农作物产量减少25%， 性能从未如此出色。拟议的参与赠款将促进开展合作研究 由我在马尼托巴大学和斯托勒企业有限公司（里贾纳，萨斯喀彻温省）的研究小组。 Stoller目前在市场上有许多增加作物产量的产品。我们已经发现了一种 绿针假单胞菌：一种细菌（绿针假单胞菌PA23），当施用于植物时，可导致早期出苗 增加了植物的大小。本提案将涉及几个问题，包括如何最好地 把细菌涂在植物上种子浸，根浸，和灌溉将进行测试，看看每一个影响 这种细菌促进生长的能力。我们将确定细菌细胞本身或 它们释放的特定产物引起植物生长促进作用。最后，我们将研究如何最好地 将细菌储存起来，以获得最大的益处。我们的植物生长促进细菌将很好地 补充Stoller现有的作物改良产品系列，为公司带来经济效益。 此外，土壤添加剂可以显着提高作物产量，不仅在加拿大， 地球仪。通过植物生长促进细菌提高植物生产力和活力， 与过量化学物质流失有关的环境损害。我们使用有益细菌的方法 化肥的地方将提供巨大的利益，加拿大农业部门和社会作为一个 整体
