摘要

叶面肥料的使用已成为植物矿质营养领域的主要创新。这些微量营养素的使用与多种工具相结合,可以促进农业综合企业的技术发展,特别是在大豆方面。因此,本研究的目的是验证通过叶片补充微量营养素与大豆形态农艺性状之间可能存在的相关性。该研究是在巴西GO州Mineiros县的野外条件下进行的。试验设计采用3 × 5因子随机区组,对应3种大豆基因型(Anta82、CD2737和N7902)和5种浓度的叶片补剂Triplus Anuais®,其保证磷含量为2%,硼含量为3.4%,钼含量为1%,镍含量为0.35%。在开花前以单剂量(0,300,600,900和1200 ml ha-1)施用叶片补充剂。通过Triplus Anuais添加300和600 ml叶片,观察到NS 7209 IPRO基因型的产量潜力最高。此外,通过田间调整提高两粒荚果、单株粒数和主要单株荚果数的平均产量,可以提高基因型的产量。

Correlations between morpho-agronomic characters of soybean supplemented via leaf with micronutrients
The use of foliar fertilizers has become the main innovation in the field of plant mineral nutrition. And the use of these micronutrients associated with multivariate tools can contribute to the technical development of agribusiness, especially in soybean. Therefore, the aim of this study was to verify the possible correlations between morpho-agronomic characters of soybean supplemented via leaf with micronutrients. The study was conducted under field conditions in the county of Mineiros, GO, Brazil. The experimental design used was in randomized blocks in a 3x5 factorial scheme corresponding to three soybean genotypes (Anta82, CD2737 and N7902) and five concentrations of leaf supplement, Triplus Anuais® with its guarantees of phosphorus 2%, boron 3.4%, molybdenum 1% and 0.35% nickel. The leaf supplement was applied in a single dose during pre-flowering (0, 300, 600, 900 and 1200 ml ha-1). The highest yield potential was observed in the NS 7209 IPRO genotype at doses of 300 and 600 ml of leaf supplementation via Triplus Anuais. In addition, field adjustments to increase the averages of pods with two grains, grains per plant and mainly pods per plant, can increase the yield of genotypes.
