Abstract
ABSTRACT
Gerbera is one of the important commercial cut flower crops and is one among the top ten cut flower of the world flower trade, which ranks fifth in the International flower trade. There is always demand for novel types with high yielding genotypes. Hence, the present study was conducted to identify the suitable gerbera cultivars under naturally ventilated polyhouse with respect to yield and quality of cut flowers at Hi-tech Horticulture Unit, Saidapur Farm, Main Agricultural Research Station, University of Agricultural Sciences, Dharwad.
Among the ten cultivars studied there were wide and highly significant variations observed for various growth, yield and quality parameters. Cultivar Cacharelle produced maximum cut flower yield (37.10/pl/yr) followed by Pre-Intenzz (35.80/pl/yr) and Winter Queen (33.80/pl/yr). The same cultivars had significant longer stalk length and bigger sized flowers compared to other cultivars. With respect to vegetative parameters like plant height, number of leaves per plant, plant spread, suckers production and leaf area were also maximum in the same cultivars.
A positive correlation was noticed between flower yield and vegetative characters; like plant height, plant spread, side shoots, leaf area and number of leaves per plant. However, negative correlation was noticed between stalk length and stalk diameter. Among the growing seasons, flower yield and quality of flower in all the varieties were higher during winter season followed by rainy and they were least during summer season. The Cv. ‘Cacharelle’ realized maximum net return of ` 3,38,020 in 560m2 area with a B:C ratio of 2.00 followed by Pre-Intenzz (` 3,17,860 ; 1.88), Winter Queen (` 2,90,980 ; 1.72) and Stanza (` 2,72,16 ; 1.62) compared to other genotypes studied.
