Abstract
Chrysanthemum is one of the most important flower crops cultivated widely in
temperate, tropical and subtropical regions of the globe. The improvement of
chrysanthemum depends on the identification of cultivars for different agro climatic
conditions. Differences in planting months would bring about a variation among the
cultivars with respect to growth, yield and flower quality parameters. The present
study was aimed for selection of suitable time of planting for a particular cultivar to
maximize the flower yield and quality inturn to get more profit.
The performance of ten different cultivars viz., Dundi, Accession No. 2,
Chitradurga Local, Autumn Joy, Garden Beauty, Accession No. 1, Winter Queen,
Karnool, Raja and Statesman, was tested in four different planting months at two
months intervals viz., June, August, October and December. Planting was done
starting from June, 2012 to April, 2013. The experiment was laidout by following two
factorial randomized complete block design with two replications.
The results revealed that the June month planting found best to produce good
quality flowers with higher yields and returns. Among the different cultivars, Automn
Joy, Winter Queen, Accession No. 2, Dundi and Karnool were vigorous in vegetative
growth. Dundi produced 100 per cent flowering even in December month planting
also, but other cultivars were specific in flowering to a particular month. Cultivars
Automn Joy, Raja and States Man cultivars did not produced flowers in December
month planting. Accession No. 1 produced flowers only in June month of planting.
Flower yield was higher in June month planted Garden Beauty, Dundi and
Karnool. The gross returns, net returns and B:C ratio were maximum in cultivars
Accession No. 2, Raja, Dundi and Karnool. Dundi even planted in December gave
comparatively more returns than other cultivars. Cultivar Dundi found better for
planting from June to December months.
