Abstract:

An experiment was conducted at Horticultural Research Farm, Mondouri, and Bidhan Chandra Krishi Viswavidyalaya during April 2015 to March 2016 to study the effect of different organic manures on growth and flowering of tuberose (Polianthes tuberosa L.) cv. Prajwal. The experiment was laid out in Randomized Block Design with three replications, with nine treatments. The treatments include vermicompost (2000 g sq/m), neem cake (400 g sq/m) poultry manure (1000 g sq m-1) and FYM (4000 g sq/m) were applied individually and all the treatments were repeated with the combination of treatments of seaweed. The observations on vegetative and reproductive growth were recorded. . Among growth parameters, plant height and number of leaves were highest in treatment T6 (Seaweed+Vermicompost @2000g/sq m), leaf length was found maximum in T8 (seaweed+ neem cake@200g/sq m) and maximum leaf breadth was found in T5 (seaweed+poultry manure@1000g/sq m). All the flower parameters varied significantly among treatments except diameter of spike. Flowering parameters like, spikes length, number of florets, weight of ten florets, length of florets and rachis length were found to be maximum in T6 (Seaweed+ Vermicompost @2000g/sq m). Weight of spikes was maximum in T8 (Seaweed+Neem cake @400g/sq m) where, floret diameter was maximum in case of T4 (Neem cake @400g/sq m).With respect to quality parameters, vase life was highest in treatment T8 (Seaweed+Neem cake @400g/sq m) and in treatment T6 (Seaweed+Vermicompost @ 2000g/sq m). And the flower yield was found to be maximum in the treatment T6 (Seaweed+Vermicompost @ 2000g/sq m). The interpretation of the data reveals that sole application of organic manures and in combinations with seaweed significantly affected the quantitative and qualitative characters of tuberose. So it may be concluded that application of seaweed+ Vermicompost @ 2000g sq m and Seaweed+Neem cake@ 400g sq m showed significant improvement in vegetative growth, flowering and post harvest attributes through increased availability of nutrients in the soil.
