Abstract

"In order to evaluate the effect of soil tillage system, fertilization and also different treatments applied to seeds on chemical composition in soybean crop, a field experiment was conducted at Research and Development Station for Agriculture Turda in 2020. Teo TD, an early soybean variety developed at RDSA Turda and registered in 2017 was used as a biological material. The compared tillage systems were: conventional tillage (plowing), reduced tillage (chisel or disk) and also no-tillage system. Four different mineral and organic fertilizers (N40P40, N40P40 + gulle, N40P40 + green fertilizer, N40P40 + gulle + green fertilizer) and various treatments applied to seeds (fungicide, insecticide, fungicide + insecticide, untreated) were also studied. All data were subjected to ANOVA using Polifact. Chemical composition (protein content, oil content, stearic acid (18:0), oleic acid (18:1), linoleic acid (18:2), and linolenic acid (18:3)) of Teo TD seeds was analyzed using NIR spectroscopy. Significant differences between some tillage systems and fertilizers were recorded in protein content, fat content and also stearic, oleic and linolenic acids content. The treatments applied to seeds influenced very significant the stearic acid and oleic acid, distinct significant the linoleic acid and significant the protein content."

土壤耕作制度、施肥和种子处理对大豆化学成分的影响

“为了评估土壤耕作制度、施肥以及不同种子处理对大豆作物化学成分的影响，2020年在图尔达农业研究站进行了一项田间试验。在rdsaturday开发并于2017年注册的早期大豆品种Teo TD被用作生物材料。比较的耕作制度是:常规耕作(犁耕)，减少耕作(凿或盘)和免耕制度。研究了4种不同矿质有机肥(N40P40、N40P40 + gulle、N40P40 +绿肥、N40P40 + gulle +绿肥)和不同处理(杀菌剂、杀虫剂、杀菌剂+杀虫剂、未处理)对种子的影响。所有数据均采用Polifact进行方差分析。利用红外光谱分析了Teo TD种子的化学成分(蛋白质含量、含油量、硬脂酸(18:0)、油酸(18:1)、亚油酸(18:2)、亚麻酸(18:3))。不同的耕作制度和肥料在蛋白质含量、脂肪含量以及硬脂酸、油酸和亚麻酸含量上存在显著差异。种子处理对硬脂酸和油酸有显著影响，对亚油酸有显著影响，对蛋白质含量有显著影响。
