Varietal performance of marigold (Tagetes spp.) under sub-tropical condition of Bihar

Abstract

A field experiment was conducted at experimental station of Nalanda College of Horticulture, Noorsarai, Nalanda, Bihar (India) to assess the varietal performance of marigold with respect to growth and yield. Thirty seven cultivars of marigold collected from different location of Bihar and West Bengal and all cultivars were arranged in factorial randomized block design replicated thrice. Data were collected on plant height (cm), number of primary and secondary branches, number of flowers/ plant, diameter of flower, average weight of flower (g), flower yield/plant (kg), yield (q/ha.) Almost all the parameters influenced significantly due to various treatments and recorded maximum average flower wt (g) with Inka yellow after that Inka Orange, Inka White and M-6 respectively which were significantly at par. The maximum flower yield/plant and flower yield (q/ha) were recorded with Pusa Narangi and Pusa Basanti, respectively. Range of flower yield varies from 39.00-249 (q/ha) while, entries M-4, M-5, M-6, Hilsa marigold, MS-1, MS-2, MS-3, MS-4, MS-5, Pusa Narangi and Pusa Basanti were recorded significantly higher flower yield (q/ha)
