Abstract
The present investigation was carried out to evaluate African marigold (Tagetes erecta L.) varieties for flower yield and quality under tarai conditions at Vegetable Research Centre, G. B. Pant University of Agriculture & Technology, Pantnagar, U. S. Nagar, Uttarakhand during November, 2017- May, 2018 with twelve varieties i.e. Pusa Narangi Gainda, Pusa Basanti Gainda, Sakata Marigold Hybrid-220 (Gold), Sakata
Marigold Hybrid-307 (Yellow), Sakata Marigold Hybrid-907 (Orange), Indo- American Hybrid Marigold, Namdhari African Marigold Double Orange, Arka Agni, Arka Bangara, Arka Bangara-2, Bidhan Marigold-1 and Bidhan Marigold-2 in randomized block design and three replications.
During the course of experiment plant height, plant spread, number of branches per plant, number of leaves per plant, days to first flower bud appearance, days to 50 per cent flowering, number of flowers per plant, flower diameter, flowering duration, fresh and dry weight of single flower, flower yield per plant, flower yield per plot, flower yield per hectare, shelf life of flower under open condition and in polythene covers, total carotenoid content and benefit cost ratio were studied. All the traits pertinent to vegetative growth, flowering and total carotenoid content were significantly influenced by marigold varieties. Highest plant height (34.00 cm), plant spread (28.13 cm) and number of leaves per plant (82.27) were found in Sakata Marigold Hybrid (Orange). Significantly maximum number of branches per plant (21.25), number of flowers per plant (100.16) and longest flowering duration (114.00 days), flower yield per plant (1947.55 g), flower yield per plot (70.11 kg) and flower yield per ha (121.72 t) and benefit cost ratio (5.05) were recorded in Arka Agni. Earliest first flower bud appearance (50.67 days) and highest single fresh flower weight (27.11 g) were found in Indo-American Hybrid Marigold whereas, dry weight of single flower was highest in the
Sakata Marigold Hybrid (Gold) (2.68 g). Days to 50 per cent flowering i.e. 88.67 days and higher total carotenoid content (523.05mg/100g) were recorded in the Pusa Narangi Gainda. Flower diameter was maximum (9.90 cm) in variety Sakata Marigold Hybrid (Yellow). Shelf life of flower under open condition (6.67 days) and in polythene (10.67 days) was observed highest in variety Arka Bangara. On the basis of the findings of present study, this may be concluded that variety Arka Agni is most suitable for commercial cultivation of African marigold for obtaining
a remunerative loose flowers yield whereas, variety Pusa Narangi Gainda can be for carotenoid content under tarai region of Uttarakhand.
