Abstract

The research was conducted in 2022–2023 on leached chernozem in Western Ciscaucasia in a two-factor field experiment. The aim of the work was to study the effect of sowing dates and sowing rates on the productivity of hybrid Klip. Four sowing dates (the first – the end of April (optimal), the second – the beginning of May, the third – the middle of May, the fourth – the end of May) and two sowing rates (60 and 80 thousand plants/ha) were studied. It was found that the highest yield (3.17–3.20 t/ha) and oil yield (1.40–1.41 t/ha) of the hybrid were obtained when sowing in the middle and the end of May at the sowing rate of 80 thousand pcs/ha
