AGROECOLOGICAL FEATURES OF SEED PRODUCTIVITYINCREASE OF WHITE MUSTARD IN THE CONDITIONS OFPODILLIA

Abstract

The purpose of the study is to establish the patterns of seed productivity formation of white mustard depending on the biological characteristics of the variety and the period of sowing seeds. Based on the results of the study during 2016-2018, the influence of sowing dates of white mustard varieties Carolina, Pidpecheretska, Podolianka on seed yield was highlighted. It was found that with the optimal early spring (first term) sowing period and soil thermal regime of 3-4°С at the depth of white mustard seed wrapping, higher seed yield was obtained compared to sowing of the second and third sowing dates. The highest yield of white mustard seeds was provided by the Podolianka variety - 2.76 t/ha. Planned measures to further increase the production of oilseeds and improve their quality are of great importance for solving the priority tasks of strengthening the economic sector. Based on the study, it was found that in order to increase the seed productivity of white mustard seeds the variety Podolianka it is advisable to sow in early spring (first term) at the level of thermal regime of the soil 3-4°C at the depth of seed wrapping, which provides a seed yield of 2.76 tons/ha and oil yield 626 kg/ha. The prospect of further research is the optimization of agro-technological measures for growing modern high-yielding varieties of white mustard.
