THE YIELD FORMULA AND PRODUCTIVITY OF CAMELINA SATIVA L. CRANTZ ON THE SOUTHERN STEPPE OF UKRAINE

It’s specified the results of three-year researches concerning the influence of preseeding treatment and foliar application by plant growth regulators on the yield formula and productivity of Stepovuy 1 variety of Camelina sativa L. Crantz. It was studied the influence of growth plants regulators on the elements of yield formula and productivity of the false flax spring under soil moisture deficit of the southern Steppe of Ukraine. It was specified the preseeding treatment increases the productivity by 54-56%; and combined with three time foliar application at the main growing periods – almost 4 time larger (1.5 t/ha in comparison with Control – 0.391 t/hа). The optimized by us resource-saving power feed system, as one of the main elements of the cultivation technology, allows us to get 1.4-1.5 t/ha crop yield. The research defined that the primary role in the crop yield formation of Camelina sativa L. Crantz belongs to background preseeding treatment by modern biologies and foliar application at the main periods of ontogeny. It is defined that the level of crop yield is determined such structure elements as: the number of branches on the plant, the number of pods, the number of seeds in a pod, and the 1000 seeds mass. It’s defined that all these factors grow a lot under the influence of preseeding treatment and foliar application by plant growth regulators
