Vegetative growth of marigold under open field conditions as influenced by rooting media

Abstract

An experiment was carried out in factorial concept with two factors i.e., varieties at two levels and rooting media at eight levels thus making 16 combinations which were replicated twice. The effect of varieties, rooting media and their interactions were found to be significant with regard to percentage establishment of rooted cuttings (%), plant height (cm), number of primary branches per plant, number of secondary branches per plant, plant spread (cm2), stem diameter (cm) and total dry weight of plant at harvest in open field (g). The variety Bidhan Marigold 1 exhibited greater percentage establishment of rooted cuttings (96.13%) than Bidhan Marigold 2 (94.17%) at 30 days after shifting into the main field. At 90 DAS, the variety Bidhan Marigold 1 exhibited highest plant height (59.03 cm), maximum number of primary branches per plant (4.66), secondary branches per plant (12.95), plant spread (945.55 cm2), stem diameter (1.28 cm) and highest total dry weight of plant (63.03 g), than Bidhan Marigold 2.
