Over a period of three years (2019-2022), 25 varieties of autumn wheat were studied at SCDA Caracal (University of Craiova), in terms of yield and its quality under different technological conditions (fertilization level and sowing time). Several aspects were addressed: the variability of the characters influencing quality and the way the applied technologies influence it; the productivity and baking quality of the tested wheat varieties, depending on the applied technologies; the stability of the studied characters for the tested wheat varieties; the ranking of the values of the studied characters expressed by a score-based ranking. The results showed that yield gain could be obtained by increasing the nitrogen dose and that the quality of the yield was significantly improved by delaying sowing. Increasing the nitrogen dose resulted in higher yields, protein content, wet gluten content, flour power and gluten index, all of which were statistically assured. The most stable character was found to be hectolitre mass, whereas yield was medium stable and the wet gluten content was unstable for all varieties tested. The highest ranked Romanian varieties were Dropia, Glosa and Șimnic 50. [ABSTRACT FROM AUTHOR]

In 2022, on the chernozem from Caracal, in the wheat soils sown on 1,100 ha in the production farms of SCDA Caracal, the non-didactic department of the University of Craiova, in two locations: Caracal and Stoenești, FOLIQ 36 Nitrogen was administered to 7 wheat varieties: Glosa, Otilia, Izvor, Avenue, Gabrio, Euclide and Caro line. Leaf samples were taken from 13 physical blocks (one not treated with foliar fertilizer and 12 fertilized with foliar in two doses) in accordance with the leaf sampling instructions approved by the Analitycal Services Laboratory of Yara UK Limited-Packlington. Macro- and micro-nutrients were determined by laboratory analysis in England as follows: nitrogen (%), phosphorus (%), potassium (%), calcium (%), magnesium (%), sulphur (%), iron (ppm), zinc (ppm), manganese (ppm), boron (ppm), copper (ppm), molybdenum (ppm). Interpretation of the results showed that a dose of 1 l/ha significantly increased the zinc content, iron content and nitrogen content of the plant; significantly distinctive also the copper and sulphur content of the plant was increased; very significantly increased were the boron content and phosphorus content of the plant. The same dose also influenced yield very significantly. In general, Gabrio, Avenue and Euclide varieties showed high yields but also high nitrogen, boron, copper, calcium and phosphorus contents.
