As the global human population continues to rise, the demand for agriculture to supply high quality food, fibre**and energy increases. At the same time, consumer pressure is mounting to reduce the environmental footprint**of agricultural production and move toward more sustainable and environmentally friendly production methods**to meet the increase in demand. Plant growth promoting bacteria (PGPB) can contribute to achieving these**goals. Previous research for KGS Group identified two proprietary strains of Pseudomonas spp. KGS Group**is a consulting engineering firm that provides a wide range of services including water resource management.**The two bacterial strains were initially isolated to assist with phosphorous solubilisation and plant uptake to**minimize movement of this essential plant nutrient from manure into water resources. Subsequent**experimentation indicated that these strains may also cause plant growth promoting effects other than improved**phosphorous nutrition on some plants. The purpose of the current Engage proposal is to quantify and better**understand these additional plant growth promoting effects, focussing on seedling vigour, seed yield and seed**quality, under field conditions with and without phosphorous fertilization in wheat and canola, two of the most**important crops to western Canadian agriculture. This research will provide vital new information on the**behaviour of these PGPBs in important crop species under field conditions and assist KGS Group in defining**the applicability and potential market for these PGPB strains.

随着全球人口的持续增长，对农业的需求也在增加，以提供高质量的食品、纤维 ** 和能源。与此同时，消费者的压力越来越大，要求减少农业生产的环境足迹 **，转向更可持续和环保的生产方式 **，以满足需求的增长。植物生长促进细菌（PGPB）可以有助于实现这些目标。KGS集团以前的研究确定了两种假单胞菌属的专有菌株。KGS集团 ** 是一家工程咨询公司，提供包括水资源管理在内的广泛服务。**这两种细菌菌株最初被分离出来，以帮助磷的溶解和植物吸收，从而最大限度地减少这种必需的植物营养素从粪肥进入水资源的运动。随后的试验表明，这些菌株还可能对某些植物产生除了改善磷营养之外的植物生长促进作用。目前Engage提案的目的是量化和更好地理解这些额外的植物生长促进作用，重点是小麦和油菜（加拿大西部农业最重要的两种作物）在有和没有磷肥的田间条件下的幼苗活力、种子产量和种子质量。这项研究将提供有关这些PGPB在田间条件下在重要作物物种中的行为的重要新信息，并协助KGS集团确定这些PGPB菌株的适用性和潜在市场。
