Abstract
A field experiment was conducted atthe Precision Farming Development
Centre, Department of Horticulture, College of Agriculture, University of Agricultural
Sciences, Bengaluru, during kharif season 2014 on “Integrated nutrient management
with drip irrigation and plastics mulching in chrysanthemum (Chrysanthemum
morifolium L.) cv. Chandini”. The experiment was laid out in randomized block
design with 3 replications and 13 treatment combinations comprising of inorganic
fertilizers, organic manures and biofertilizers. The results of the experiment indicated
that treatment 11 (75% RDF+VC+VAM) recorded significantly higher growth,
flowering and quality parameters over control. Maximum highest plant height (85.93
cm), number of lateral branches (116.03), number of leaves (720.00), plant spread in
bothN-S X E-W direction (4096.68cm2), and yield attributes such asearly flower bud
initiation (104.68 days), 50 per cent flowering (141.38 days), days to complete
flowering (163.70 days), number of flowers per plant (184.32), number of flower per
m2(921.61), flower diameter (4.10 cm), shelf life (3.96 days), estimated yield of
flowers per plant (295.83 g/plant), yield of flowers per sq m (1.67 kg/sq m), yield of
flowers per ha (16.71 tons/ha). Significantly higher available major nutrients
(nitrogen) was recorded in treatment receiving (205.72 kg/ha) 100 per cent of RDF +
Azo + VC + VAM (T12) and other available major nutrients like phosphorus (34.80
kg/ha) and potassium (280.68 kg/ha) was recorded in treatment receiving (T11) Azo +
VC + 75 per cent recommended NPK. The economic analysis clearly indicated that
net returns/ha and B:C ratio was highest in the plots treated with (T11) Azo+ VC + 75
per cent recommended NPK (Rs. 7,60,002 and 2.32 respectively) and this finding can
be used in making chrysanthemum production more profitable.
