The aim is to establish the processes of formation of yield and sowing qualities of white annual clover seeds depending on the main tillage and methods of harvesting in the conditions of the Southern Steppe of Ukraine. Research methods: field, visual measuring and weighing, laboratory, mathematical and statistical, computational and comparative. It is established that the optimal conditions for the growth and development of white annual clover developed during the main tillage – plowing 25-27 cm (factor A), when the average seed yield was 0,56 t/ha - NIR05A – 0,03 t/ ha). According to factor B (harvesting method), the highest seed yield - 0.52 t / ha was obtained by direct harvesting method using desiccation (NIR05В – 0,05 t/ha). The maximum average yield of crop seeds – 0,61 t/ha was set for plowing (25-27 cm) and the use of desiccation (direct method of harvesting). In the experiment with desiccant application rates, the maximum yield of white one-year-old Cranberry seeds – 0,63 t/ha was obtained using Reglon Super 150, SL, PK application rate of 6,0 l/ha (NIR05 – 0,010 t/ha). The maximum conditionally net profit – 49,3 thousand UAH/ha, at the lowest cost of one ton of seeds – 19,1 thousand UAH and the highest level of profitability – 423% get for the use of plowing (25-27 cm) and desiccation. Using different rates of desiccant application, the maximum value of gross output per 1 ha – 63,0 thousand UAH/ha was obtained on crops of white annual clover Pivdennyi, where Reglon Super 150, SL, PK was used, application rate 6,0 l/ha . In this case, the maximum conditionally net profit was obtained – 51,7 thousand UAH/ha, the lowest cost of one ton of seed – 17,9 thousand UAH; the level of profitability was the highest and amounted to 459%.
