| Popis: | The article presents the results of studies on the influence of exogenous seed treatment and foliar dressing of grass stand with complex sulfur-containing microelement fertilizers on seed productivity, technological and biochemical properties of the fruit of the milk thistle of the variety Debut. The greatest positive effect was achieved with the exogenous treatment of milk thistle seeds with a complex sulfurcontaining fertilizer Megamix-Zinc, the fruit yield – 1.23 t/ha, increase – 0.34 t/ha (38.2%); the content of oil – 35.9%; of protein – 29.8 and 7.0%; in relation to the control it increased by 7.6%, the content of essential amino acids was 149.5 mg/g of DM (dry matter) (in control – 124,0 mg/g of DM). With double foliar top dressing of milk thistle crops during the rosette and budding phase, the fruit yield amounted to 1.06-1.19 t/ha, in relation to the control it increased by 0.17-0.3 t/ha; oil content – by 2.9-7.0%, protein – by 1.4-2.9%. The highest yield of milk thistle seeds of 1.47 t/ha was obtained with foliar dressing of plants and seed treatment with Megamix-Zinc. The oil content was 35.3%, protein – 25.4%, flavonolignans – 3.06%, acid number – 0.28. |
