Abstract

Potato (Solanum tuberosum, L.) is one of the most responsive crops to fertilizer application, which drives theneed to rationalize and make the most of nutritional resources in efficient and sustainable management. Basedon the hypothesis that the organomineral is a great alternative to increase potato productivity (Ágata andAtlantic cultivars) and that it can be indicated as a substitute for mineral fertilizers, this study aims to evaluatethe effect of organomineral doses applied in the planting furrow on potato productivity to identify the bestlevel of mineral fertilizer replacement. A study was conducted in the city of Cristalina (state of Goiás, Brazil),evaluating the replacement of 40, 60, 80, and 100% of mineral fertilizer (standard) provided via organomineralfertilizer in two widely cultivated varieties. The total productivity and the productivity in classes were monitored,as well as the nutrient contents in the leaves. The results showed that the organomineral is a great alternative toincrease potato productivity and can be indicated as a substitute for mineral fertilizers. For the cultivar Ágata,an organomineral dose of 80% is recommended concerning mineral fertilization. On the other hand, for theAtlantic cultivar, the same dose of mineral fertilizer is recommended. In both cultivars, there was an increase intuber size with organomineral fertilization, which indicates greater efficiency in tuber productivity.

有机矿物质作为马铃薯种植中矿物肥料的替代品

马铃薯（Solanum tuberosum, L.）是对施肥反应最灵敏的作物之一，因此需要合理利用营养资源，进行高效和可持续的管理。本研究假设有机矿物质是提高马铃薯（Ágata 和大西洋栽培品种）产量的最佳替代品，并可用作矿物肥料的替代品，因此旨在评估在种植沟中施用有机矿物质剂量对马铃薯产量的影响，以确定矿物肥料的最佳替代水平。在克里斯塔利纳市（巴西戈亚斯州）进行了一项研究，对两个广泛种植的品种使用有机矿物质肥料替代40、60、80和100%的矿物质肥料（标准）进行了评估。对总产量和分级产量以及叶片中的养分含量进行了监测。结果表明，有机矿物质是提高马铃薯产量的最佳选择，可作为矿物肥料的替代品。对于 Ágata 栽培品种，建议使用 80% 的有机矿物质作为矿物质肥料。另一方面，对于大西洋栽培品种，建议使用相同剂量的矿物肥料。这两个栽培品种在施用有机矿质肥料后，块茎的体积都有所增加，这表明块茎的生产效率更高。
