Abstract Goal. Determine the influence of sowing terms, sowing method and depth of seeding on the formation of biometric indices of thistle plants in the conditions of the Right Bank Forest-steppe of Ukraine. Methods. Field, analytical and statistical. Results It was established that in variants, where the seed was carried out per 1 cm, the plants were low-growth, even octomized. They were distinguished by a smaller gabit. The highest plants formed the first line of sowing broad-leaved crops when seeding 2 and 3 cm, plant height reached 135.8-139.3 cm. The largest number of seeds in the basket were allocated variants of sowing in the first decade of April with a width of rows of 45 cm and depth of seeding 2 and 3 cm. This indicator was 123.5 and 124.2 pc from the plant, that is, with an excess of control at 22.4 and 21.7 pc. The largest amount of seed from a plant was 1316.2 pc. Marked on the first-line variant (at the level of the thermal regime of the soil 8-10 ° С) sowing with a width of between rows of 45 cm and depth of seeding of 3 cm. Analysis of the correlation of plant productivity indices and factors The research shows that the yield of the spotted thistle fruit significantly depends on the biometric parameters, such as: the number of seeds from the plant (correlation coefficient r = 0.82), the number of seeds in the basket (correlation coefficient r = 0.89) and plant height (correlation coefficient r = 0.83).
