Abstract
The present study was aimed to find out the influence of integrated nutrient
management (INM) on growth, yield and quality of double daisy at new orchard,
floriculture unit, Department of Horticulture, College of Agriculture, University of
Agricultural Sciences, Dharwad, during kharif season of 2010-11. The experiment
was laid out in randomized complete block design with three replications and eight
treatment combinations.
The growth parameters, maximum plant height (62.34 cm) was recorded with
the application of Azospirillum, PSB, Vermicompost equivalent 50 % RD’N’ 50 per
cent recommended NPK. Similarly, the maximum number of branches per plant
(30.90), number of suckers per plant (17.05), total dry matter production (43.73 g) and
most of the physiological parameters were noticed in the same treatment. It was
significantly superior to all other treatments.
The flower characters like stalk length (49.97 cm) and flower diameter (3.06
cm) were significantly higher in treatment receiving Azospirillum, PSB,
Vermicompost equivalent 50% RD’N’, and 50 per cent recommended NPK. The
maximum number of flowers per plant (296.33), number of flower spikes per plant
(7.97) number of flower spikes per hectare (8.74 lakhs) and maximum vase life (5.12
days) were also higher in the same treatment. The application of FYM equivalent 50
per cent RD’N, and 50 per cent recommended NPK resulted in lowest value of these
parameters.
The economics analysis clearly indicated that net returns per hectare and B:C
ratio was the highest in the plots treated with Azo+PSB+VC equivalent to 50% RD
‘N’ + 50% RDF (Rs. 386430.72 and 7.61 respectively) and these findings can be used
in making double daisy production more profitable.
