Considered the economic engine of many countries, the coffee culture represents an important component of the agricultural chain in Brazil. The growing values of commercialization, planting areas, and crop productivity require the acquisition of quality seedlings, which must receive adequate nutritional support through efficient fertilizers. Slow and controlled-release fertilizers, such as organominerals, gain prominence when it comes to increasing efficiency in the use of phosphorus, as well as plant growth-promoting bacteria (PGPB) with phosphate solubilizing characteristics. This study aimed to evaluate the effect of different sources of mineral and organomineral fertilizers, inoculated and non-inoculated with PGPB on the quality parameters of coffee seedlings. In general, the P sources used in the experiment positively interfered with the development of coffee seedlings. This proves that there is a need for nutritional supplementation for the good development of the seedlings. Among the sources used, the organomineral in granulated form showed better performance in coffee seedlings' growth and physiological parameters, proving to be a viable alternative to commonly used fertilizers. The addition of PGPB showed a significant advantage for seedling quality variables.
咖啡文化被视为许多国家的经济引擎，是巴西农业产业链的重要组成部分。商业化价值、种植面积和作物产量的不断增长需要优质苗木，而优质苗木必须通过高效肥料获得充足的营养支持。缓释肥料，如有机矿物质肥料，在提高磷的利用效率方面备受关注，同时具有解磷特性的植物促生细菌（PGPB）也受到关注。本研究旨在评估不同来源的矿物肥料和有机矿物肥料，接种和未接种PGPB对咖啡苗木质量参数的影响。总体而言，实验中使用的磷源对咖啡苗木的生长有积极影响。这证明了为苗木的良好生长提供营养补充的必要性。在所使用的肥料中，颗粒状有机矿物肥料在咖啡苗木的生长和生理参数方面表现更好，证明是常用肥料的可行替代品。添加PGPB对苗木质量变量显示出显著优势。
