Impact of integrated nutrient management on growth, flowering, yield and economics of tuberose.

An experiment was conducted for three consecutive years during rabi from 2010-11 to 2012-13 at Floricultural Research Station, Hyderabad to study the influence of integrated nutrient management practices to improve the growth and flower yield of Tuberose cv. Hyderabad Double. The treatments consist of combination of organic fertilizers and bio inoculants along with different levels of NPK (100%, 75% and 50%RDF). Compared to 100 % RDF with FYM alone, application of 75% RDF in integration with farm yard manure (FYM), vermicompos (VC), Azospirillum (AZO) and phosphate solubilizing bacteria(PSB) (T4) has significantly yielded maximum number of spikes per plant (2.33) with increased spike length, rachis length, number of florets per spike and also maximum number of bulbs per plant (32.60). B: C ratio ranged between 2.09 - 2.60 with its maximum exhibited by 75% RDF with FYM, VC, AZO and PSB(T4) followed by 50 % RDF with FYM, VC, AZO and PSB (T7). [ABSTRACT FROM AUTHOR]
