The effect of harvesting at different stages on growth and yield was studied in chicory (Cichorium intybus L.) Cv. TLD. Leaf area and number of leaf progressively increased up to 120th day. The highest root length was noted on the 180th day and the highest girth on the 150th day. The girth/length ratio was high at 105 days. The mean weight of root beyond the 120th day varied within narrow limits. The fresh weight of tops and roots was high on the 120th day and less in subsequent stages. The top/root ratio was high in the early stages and the ratio was low on the 120th day. Dry weight of tops and roots was high on the 120th day. Harvests beyond 135th day resulted in decrea1226se in dry weight of the roots and tops. The highest harvest index was recorded on the 180th day. Harvesting on the 120th day after sowing recorded high fresh root yield and dry matter produc
