Effect of organic manures, inorganic fertilizers and biofertilisers on vegetative and floral characters of tuberose (Polianthes tuberosa L.) cv. ‘Single’

Abstract

An investigation was carried out at carried out at the farmer’s field in the village Hinjili of Hinjilikatu block of Ganjam district of Odisha,India. during the period from April, 2017 to March, 2018to find out the effect of organic manures, inorganic fertilizers and biofertilisers on vegetative and floral characters of tuberose (Polianthes tuberosa L.) cv. ‘Single’. The treatments consist of different levels of NPK i.e 100%, 75% and 50%RDF along with combination of organic fertilizers and bio inoculants.The observations were recorded for growth and flowering parameters. Application of 75%RDF + FYM @1Kg/m2 + Vermicompost @300g/m2 + Azospirillum @2g/plant) + PSB @ 2g/plant showed significant influence on spike length (86.31cm),rachis length (25.83cm), number of spikes per plant(2.62), number of floret per spike (39.82), flower yield per plant(129.05g), flower yield per hectare (7.17t) and), fresh weight of cut spikes (24.23g), which was found better over all other treatments.
