| Abstract:
The plant density of red chicory -“radicchio rosso”- (Cichorium intybus L. var. foliosum Hegi) was studied at a field in Linares, south central Chile (35° 45' SL and 71° 85' WL). Four and five plants/m were established, using a single or a double planting line/row. The distance between rows was 0.60 m. The experimental design was a randomized complete block in a factorial arrangement. The treatments were 60000 (T1), 80000 (T2), 130000(T3) and 170000 (T4) plants/ha. The average total fresh weight/plant, the marketable fresh weight/plant and head size were higher at the lower plant density. The total yield was higher at the treatment with 4 plant/m and a double planting line/row. The highest marketable and export quality yield was obtained with the treatment T1 (4 plants/m, single planting line/row). The lowest marketable yield was observed in the highest plant density treatment. The critical plant density was 0.2 m with a single row. | |
