A study by Uman National University of Horticulture has found that the tape method of sowing chicory salads, which increases the number of plants per unit area, leads to higher yields. The study compared the tape sowing scheme to wide-row sowing and found that the tape method significantly increased the yield of chicory lettuce escariol and endive. The variety of chicory lettuce escariol had a greater impact on yield (13.5%) than the variety of chicory lettuce endive (7.9%), but other factors also influenced the total yield.
