Abstract

Analyses of potential sources and products that aim to balance nutrients in soil and plants; improve physical, mineral, and biological attributes of soil; and reduce environmental impacts require greater attention. Therefore, the aim of this study was to evaluate the agronomic efficiency of organomineral fertilizers (OMF) in Atlantic potato cultivar. The experimental design was a randomized complete block design (RCBD), with four treatments and six replicates. The treatments consisted of NPK mineral fertilizers (recommended according to soil analysis and nutritional crop requirements), as control, and NPK plus OMF according to composition and form of application (planting, ridging, and leaf), referred to as managements A and B, which indicate the amount of nutrients that the plants received. Therefore, treatments with OMF were designated as: P-OMF(A): organomineral fertilizer management (A) applied via planting furrow; PR-OMF(B): organomineral fertilizer management (B) applied via planting and ridging, and PR-OMF(B) + L-OMF(B): organomineral fertilizer management (B) applied via planting, ridging, and leaf application. The applications of P-OMF(A) and PR-OMF(B) + L-OMF(B) resulted in positive effects on Special Class production and total productivity of Atlantic potato tubers, which increase were between 12% and 16% and 11% to 15.5%, respectively. The application of PR-OMF(B) + L-OMF(B) improved their soluble solid content by 2.7% compared to the control (absence of OMF application). Therefore, organomineral fertilizers have the potential for improving the quantitative and qualitative attributes of potatoes.

有机肥促进大西洋马铃薯种植
分析旨在平衡土壤和植物养分的潜在来源和产品;改善土壤的物理、矿物和生物特性;减少对环境的影响需要更多的关注。因此,本研究旨在评价有机有机肥(OMF)在大西洋马铃薯品种上的农艺效益。试验设计为随机完全区组设计(RCBD), 4个处理,6个重复。处理包括氮磷钾矿质肥料(根据土壤分析和作物营养需求推荐)作为对照,以及根据组成和施用形式(种植、垄地和叶片)施用氮磷钾加OMF,称为管理A和管理B,这表明植物接受的养分量。因此,施用有机肥的处理分为:P-OMF(A):通过种植沟施用有机肥管理(A);PR-OMF(B):通过种植和垄施的有机肥管理(B), PR-OMF(B) + L-OMF(B):通过种植、垄施和叶片施用的有机肥管理(B)。施用P-OMF(A)和PR-OMF(B) + L-OMF(B)对大西洋马铃薯特级产量和总生产力分别提高了12% ~ 16%和11% ~ 15.5%。施用PR-OMF(B) + L-OMF(B)可溶固形物含量较对照(未施用OMF)提高2.7%。因此,有机肥具有改善马铃薯数量和质量属性的潜力。
