dc.description.abstractABSTRACT The present investigation entitled, “Integrated nutrient management studies in tuberose (Polianthes tuberosa L.) were carried out at the Experimental Farm of the Department of Floriculture and Landscaping of Dr. Y.S. Parmar university of Horticulture and forestry, Nauni, Solan (H.P.) during 2009-2010. The experiment was laid out in Randomized Block Design having 16 treatment combinations of chemical fertilizers and biofertilizers, replicated thrice in a plot size of 1m x 1m and spacing 25cm x25cm. The observations were recorded on days taken for emergence of bulbs, percent sprouting of bulbs, number of leaves per plant, plant height, number of days taken for spike emergence, spike length, number of days taken for basal florets opening, number of florets per spike , duration of flowering, fresh weight of spike, fresh weight of 100 florets, florets size, number of spike obtained per plant, number of bulbs produced per plant, average root length per plant, weight of bulbs per plant, average size of bulbs per plant and analysis of NPK in the soil. The results revealed improvement in growth and flowering parameters of tuberose when fertilized with biofertilizers i. e. Azotobacter and PSB (each @ 5 g/ plant) alone and in combinations with chemical fertilizers. The earliest emergence of bulbs (8.16 days), more number of leaves (72.56), tallest plants (106.70 cm), early emergence of spike (61.10 days), longest spike (96.70 cm), early opening of basal florets (72.56 days), more number of florets (38.33), heaviest spike (45.68 g), maximum weight of 100 florets (122 g), produced more bulbs (25.83), longest root (19.97 cm) and more availability of K (149.94) were recorded in treatment consisting of Azotobacter + PSB + NPK @ 15, 11.2, 9.3 g/ m2. Longest duration of flowering was recorded in the treatment consisting of Azotobacter + NPK @ (15, 11.2, 9.3g/ m2), whereas, largest floret in PSB + NPK @ 15, 11.2, 9.3 g/m2, however, heaviest and largest bulbs were recorded in PSB + NPK @ 20, 15, 12.5g/m2. The availability of N and P content was maximum in Azotobacter + PSB +NPK @ 20, 15, 12.5 g/m2. However, these all parameters were found to be statistically at par with treatment consisting of Azotobacter + PSB + NPK @ 15, 11.2, 9.3 g/ m2. The parameters per cent sprouting of bulbs and number of spikes obtained per plant were not affected significantly by the different treatmentsen_US
