African marigold (Tagetes erecta L.) is a herbaceous annual flowering plant belonging to family Asteraceae. Apart from its popular use in landscape gardening and garland making, it is now gaining popularity as a natural source of food colour. It is found in different colour shades of yellow and orange with different fragrance. A study was conducted in summer rice fallows of Wayanad during 2016-17 to evaluate the performance of 3 hybrids of marigold based on vegetative, flowering and yield characters. The experiment was laid out in Randomized Block Design with 5 replications and 16 plants per replication. As per the observations taken at vegetative stage, the maximum height was observed in Garland Orange (111.36 cm). The hybrid with the highest plant spread and number of branches gave the highest flower yield. Garland Orange exhibited the highest plant spread (26.25 cm, 42.19 cm, 49. 49 cm) and number of primary branches (4.43, 8.00, 15.54) at 30, 60 and 90 days after transplanting. At the flowering stage, the minimum number of days taken for 50 per cent of flowering (95.22 days) was observed in Maxima Yellow which is on par with Garland Orange (95.67 days). The yield parameter, such as number of flowers per plant was highest in Maxima Yellow (75.09) followed by Inca Yellow (67.93). The highest individual flower weight of 6.20 g was reported in Garland orange. Yield per plant (298.7 g) and Yield per plot (4.72 kg) was maximum in Garland Orange followed by Inca yellow (251.5 g and 4.02 kg, respectively). Among the 3 hybrids, Garland Orange performed better in the humid subtropical region of Wayanad followed by the yellow hybrid, Inca Yellow. | Evaluation of African marigold (Tagetes erecta L.) in summer rice fallows of Wayanad, India
