Sweet corn (Zea mays L.) belongs to the Gramineae family, var. rugosa (Bonof) convar. Saccharate (Sturt.) and can be distinguished from normal corn by presence of one or more mutant genes that affect carbohydrate metabolism in endosperm. Purpose of this research is to compare behavior of sweet corn hybrids created at SCDA Turda, but also foreign hybrids, in terms of quality elements and chemical composition, in conditions of Transylvania plateau, in two localities: Turda and Viişoara. As biological material following domestic sweet corn hybrids were chosen: ‘Prima’, ‘Estival’, ‘Deliciul verii’, ‘Dulcin’, ‘Delicios’, ‘Estival M’ and foreign hybrid ‘Jubilee’. These hybrids were also analyzed in terms of chemical composition. Weight of ‘Estival’ hybrid has the best behavior in both localities; as regards to cobs length, ‘Delicios’ hybrid has registered increases very significant positive, differences between plant height in the two localities confirm significant influence of environment on formation of this important typical qualitative characteristics, highest performances in terms of β-cryptoxanthin and zeaxanthin content, are recorded by ‘Jubilee’ in both localities, ‘Deliciul Verii’ hybrid records significant value for lutein content, also recording an important addition of carbohydrates in Turda, ‘Prima’ and ‘Estival’ hybrids recorded highest values of sucrose in both localities.

"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."
