“Effect of planting dates and mulching on growth and flowering of tuberose (Polianthes tuberosa L.) cv. Sikkim Selection” was studied at the Research farm of Department of Floriculture and Landscape Architecture, Dr YS Parmar University of Horticulture and Forestry, Nauni, Solan (HP) during 2016-2017. The experiment was laid out in Randomized Block Design (Factorial) having 12 treatment combinations with three planting dates . 20th May, 15th June and 10th July along with 3 mulching material . dry grass mulch, black plastic mulch and transparent plastic mulch with control treatment and each treatment was replicated thrice. The results showed that 20th May planting gave the best results in terms of all the growth and flowering parameters and tuberose plants mulched with black plastic established significantly with superior plant and yield parameters. Amongst various interactions crop planted on 20th May with black plastic mulch showed best results in various growth and flowering parameters like early sprouting of bulb, earliest spike emergence, maximum spike length, maximum rachis length, maximum number of florets per spike, maximum fresh weight of spike, maximum duration of flowering, largest sized bulb. Based on the findings 20th May planting and black plastic mulch were found to be best treatments. | Effect of planting dates and mulching on growth and flowering of tuberose (Polianthes tuberosa L.) cv.
