"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."
