Abstract:
The main objective of the study was to evaluate the two species of the cockscomb in North Karnataka conditions for growth and flowering parameters in Rabi and summer season. Twenty genotypes of celosia were used for the study. The experiment was conducted in Floriculture and Landscape Architecture department of Kittur Rani Chennamma College of Horticulture, Arabhavi. The experiment was laid out in Randomized complete block design (RCBD) and each treatment was replicated twice. Here maximum plant height (61.15 cm and 65.41 cm), number of leaves (142.30 and 145.75) was observed in Celosia cristata var. Chief Gold in both seasons. Maximum leaf length was found in Celosia cristata var. Armor Purple (15.73 cm) in Rabi season, whereas in summer season Celosia cristata var. Chief Gold (145.75) recorded maximum results. Maximum leaf area was recorded in G₅ (2701.88 cm²) during Rabi and G₂ (2633.37 cm²) in summer. However, Celosia plumosa var. Kimono Rose took minimum days (5.60 and 5.85 days during Rabi and summer season) for first flowering, maximum days for fifty per cent flowering took by Celosia plumosa var. Kimono Red (13.70 days and 13.82 days) in Rabi and summer season. Whereas, Celosia cristata var. Chief Carmine (72.85 days and 73.84 days) and Chief Fire (74.40 days and 75.05 days) recorded maximum days taken for fifty percent senescence of flowers during Rabi and summer season.
