Title: QUANTITY AND QUALITY OF WHITE MUSTARD SEED YIELD DEPENDING ON SULPHUR FERTILIZATION
Abstract: Background. In white mustard cultivation for seeds, in addition to basic NPK fertilization, fertilization with sulphur is of great importance. Sulphur affects the proper use of nitrogen in Brassicaceae and that stimulates their development and yield. The aim of the present research was to evaluate the effect of various sulphur doses on yield quantity and the chemical composition of seeds of three traditional white mustard cultivars. Material and methods. A field experiment was carried out in the years 2007–2009 in the weather conditions of south-west Poland (Lower Silesian Voivodeship). The experiment was set up as a split-plot design. The primary factor was white mustard cultivars: Metex, Nakielska, and Radena. The secondary factor was diversified sulphur doses: 0, 10, 20, and 30 kg·ha-1. Results. The highest white mustard seed yield was obtained from the cultivar Nakielska when fertilized with 10 kg·ha-1 S or 20 kg·ha-1 S. The cultivar Nakielska was also characterized by the highest of all the studied cultivars crude fat productivity per 1 ha at the applied fertilization rates of 10 kg·ha-1 S and 20 kg·ha-1 S, and the highest total protein productivity after the application of 20 kg·ha-1 S. Total protein and crude fat contents in seeds were significantly modified by the weather conditions in the study years. Conclusion. The study demonstrated that in white mustard cultivation for seeds the optimal sulphur dose amounts to circa 10-20 kg·ha-1, and that it is necessary for high yield. Also, the high yield-forming potential of the seed cultivar Nakielska was confirmed.
