The field trial with white mustard grown as main (early sowing) and stubble (late sowing) crop was set up at the experimental field of the Institute of Field and Vegetable Crops, Bački Petrovac. Stubble crop variant was irrigated twice using 30 mm of water. The plant material sampling was done prior to harvest for measurements and chemical analysis of seed, pod and stem. Seed of the main crop production was harvested at the beginning of August while that from stubble crop at the end of October. Height of plants grown as stubble crop was lowered by 6 %, seed yield by 20 %, and, also, a reduced harvest index was recorded when compared to the main crop results. 1000 seed mass and the number of seeds per fruit were similar in both sowing variants. Content of fatty oil, representing one of quality parameters, was somewhat higher in seed of main crop variant. The distribution of total nitrogen by plant organs was different. The highest nitrogen was found in seed, at both sowing terms, whereas considerably lower in stem and pod. A higher nitrogen content was recorded in all the plant organs grown as stubble crop when compared to those of main crop.
