The purpose of the work is to improve the elements of agricultural technology of a new grade of sweet white one-year old Yuzhny in the conditions of the south of Ukraine. Determine the optimum time for sowing, seeding rates and the effectiveness of the use of Treflan and Pulsar herbicides with different rates of application. Research methods: field, visual, laboratory, mathematically statistical, calculating and comparative. As a result of the fulfillment of the task for 2017, the optimal elements of the technology for growing the white clover seeds of the annual one were determined. Studies have established that optimum conditions for the growth and development of white white melon plants were formed during sowing in the first decade of April, when the average yield of seeds was 0.43 t / ha (NIR05 - 0.028 t / ha). The highest yield of seeds, an average of 2017 - 0.49 t / ha was obtained at a seeding rate of 2500000 pcs. / Ha (NIR05 - 0.032 t / ha). In the experiment with herbicides, the maximum productivity of seeds of the white clover of the white annual Yuzhny grade of 0.48 t / ha was obtained for the use of Pulsar 40 herbicide with a rate of application of 1.0 l / ha (NIR05 - 0.062 t / ha). The best indicators of the economic efficiency of cultivation were obtained by seeding in the first ten days of April with a seeding rate of 2,500,000. / Ha, which ensured the receipt of share-net profit - 42.5 thousand UAH / ha with the lowest cost of 1 ton of seeds - 13 20 thousand UAH / t and a high level of profitability - 321.9%. In studies using herbicides, the maximum value of gross output from 1 hectare was 48.0 thousand Grn / ha was obtained on the crops of the sweet clay of the white annual Yuzhny grade, where the herbicide Pulsar 40 was applied with a rate of application of 1 l / ha. This option also received the maximum conditional-net profit in the experiment - 41.5 thousand UAH / ha and set the lowest cost of one ton of seed - 13.5 thousand UAH. The final indicator of economic efficiency - the level of profitability was high at the same time and amounted to 307.4%.
