Abstract
A field experiment was conducted to ascertain influence of type of planting
material and nutrition on growth, flowering and yield in African marigold (Tagetes
erecta L.) var. Calcutta orange at Research Block Department of Floriculture and
Landscape Architecture, College of Horticulture, Haveli Farm, University of
Horticultural Sciences, Bagalkot during 2015-2016. The treatment details include four
different forms of nutrition (RDF, INM, farmers practice and farmers practice for
organic cultivation) impose on two type of planting material (Seedlings and Rooted
cuttings) and treatments are replicated thrice.
The study revealed that there was a variable response with respect to growth,
yield and quality parameters of marigold var. Calcutta orange for different type of
planting material and nutrition. The results indicated significant increase in vegetative
parameters such as plant height (36.81 cm), number of primary branches (14.90) and
plant spread (1948.79 cm2) were recorded in P1N2 (Seedlings + INM). All the
vegetative parameters were higher with INM treatment for both type of planting
material.
Flowering characters such as early days taken for bud initiation (37.32 days),
flower initiation (40.61 days) and 50% flowering (50.24 days) were recorded with
P1N2 (Seedlings + INM). Flower yield (521.28 g/plant), (12.96t/ha) were higher with
plants which propagated through seed that receives INM treatment. Increased higher
xanthophylls (1.91 mg/g) and chlorophyll (9.24 mg/g) content were recorded with
P2N2 (Rooted cuttings + INM). Highest net return (2,77,661) and highest benefit cost
ratio (3.49) was observed in P1N2 (Seedlings + INM).
