Description |
Gerbera is one of the important commercial cut flower crops. It 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 cut flowers at Saidapur Farm in Hi-tech Floriculture Unit, Main Agricultural Research Station, University of Agricultural Sciences, Dharwad and also to find out the best chemical preservative for enhancing the vase life of gerbera cut flowers. Among the eleven cultivars studied there were wide and highly significant variations observed for various growth, floral, cut flower yield and quality parameters. The Cv. Lexus (38.82) produced maximum number of quality cut flowers followed by Alberino (37.20), Scilla (36.95) and Bonnie (31.26). The same cultivars were also produced the longest stalk length, bigger sized flowers and number of ray florets compare to other cultivars. With respect to vegetative parameters like number of leaves per plant, plant spread, suckers production, leaf area and leaf area index were also maximum in the same cultivars. The positive correlation was noticed between flower yield per plant, flower diameter, stalk length and length of ray florets. Similarly plant spread and number of leaves also showed positively and significant association with flower yield, flower diameter and length of ray florets. The Cv. ‘Lexus’ realized maximum net return of Rs. 2,70,672 in 560m2 area with a B:C ratio of 2.65 followed by Alberino (Rs. 2,55,120; 2.50), Scilla (Rs. 2,52,720; 2.48) and Bonnie (Rs. 1,98, 096 ; 1.94) compared to other genotypes studied. In vase life study among the chemical preservatives (viz., citric acid, silver nitrate, aluminum sulphate, calcium nitrate and 8-HQS) tried citric acid @ 200ppm recorded maximum vase life of gerbera (11.48 days) followed by AgNO3 @ 400ppm (10.9 days). |
