| Abstract | Purpose. The research was supposed to establish the optimal sowing date of chicory depending on the variety, and to find out the impact on yield and quality. Methodology. It was used generally accepted research methods. Paying high attention to biometric indexes of plant growth and yield. Results. It was proved that the variety of escariol Vognysche was characterized by the small number of leaves – 26,4–25,6 pcs./plant. Red Ball, Indigo, Palla Rosa and Scherbet varieties showed higher results for sowing in the III decade of May and the number of leaves was 31,2–31.7 pcs./plant. The weight of the plant was higher in the Vognysche, Indigo, and Red Ball varieties for sowing in the I decade of May – 242–296 g. In the III decade of May, the Palla Rosa and Vognysche varieties had a higher mass - 258–275 g. High yields of chicory varieties Vognysche and Indigo were obtained for sowing in the I decade of May – 32,9 and 30,3 t/ha, which exceeded the control by 4,7 and 2,1 t/ha. The best chemical composition of commercial products of chicory escarole was observed in Indigo, Red Ball varieties for sowing in the I and the III decade of May. It has been proven that the optimal sowing date for chicory escarole are the I and III decades of May. Conclusions. The results of the research established that in the Southern Steppe of Ukraine, the optimal period for sowing chicory lettuce escarole in open ground for the Vognishche and Indigo varieties is the І decade of May during which 32.9 and 30.3 t/ha were obtained, and for the Palla Rosa, Vognishche varieties, sowing in the ІІІ decade of May – 28.6 and 30.5 t/ha. The best chemical composition of marketable products of chicory lettuce escarole was obtained from Indigo and Red Ball varieties for sowing in the 1 and ІІІ decade of May. | ||
