Description A study was conducted during 2012-2013 to evaluate different gerbera cultivars to assess their performance in growbags and soil media under naturally ventilated polyhouse to study the vegetative, flowering and post harvest behaviour for cut flower production at Horticulture College and Research Institute, Dr. Y.S.R. Horticultural University, Anantharajupet, Y.S.R. Kadapa district of Andhra Pradesh. The experimental trial was laid out in RBD with three replications and 14 treatments (14 cultivars) viz., Salvadore, Sangria, Intense, Rosalin, Silvester, Cacharelle, Sunway, Primrose, Zingaro, Dune, Danaellen, Shimmer, Dalma, Imperial with plant and line spacing of 30 cm x 30 cm. Maximum plant height (47.13 cm and 28.23 cm) was recorded by the cultivars Sangria and Intense in soil and growbags respectively at 210 DAP. The cultivars Sangria and Silvester recorded maximum plant spread of 76.33 cm and 42.26 cm at 210 DAP in soil and in growbags respectively. The cultivars Sangria and Zingaro registered maximum leaf length (42.42 cm and 26.47 cm) whereas the cultivars Salvadore and Silvester produced broader leaves (18.70 cm and 10.86 cm) at 210 DAP in soil and in growbags respectively. Maximum leaf area of 537.31 dsm2 and 351.95 dsm2 was recorded in the cultivars Sangria and Silvester in soil and in growbags respectively. When compared with all the cultivars first flower bud appearance was found 38.20 days after planting in cv. Silvester but the same cultivar took maximum number of days to establish and to putforth new flower bud by taking 83.10 days in growbags. The cv. Zingaro took less number of days to bud burst (7.13 and 8.53 days) in soil and in growbags respectively whereas in soil cv. Rosalin (4.20 days) and in growbags cv. Silvester (5.20 days) reached early to harvestable stage from bud burst.
The cultivar Cacharelle produced flowers of longer stalk length (85.60 cm and 59.18 cm) both in soil and in growbags whereas, the cultivars Cacharelle and Silvester produced flowers with larger diameter of 13.10 cm and 12.21 cm in soil and growbags respectively. The cv. Sangria registered as a high yielder among the 14 cultivars of gerbera by producing maximum number of cut flowers per plant per year (37.01) and maximum number of flowers per square metre per year (258.87) when soil is used as media. In tap water, the cv. Salvadore lasts longer in vase for 8.67 days whereas the cv. Rosalin lost the consumer acceptability earlier among the cultivars tested and found fresh for only 5.53 days. The cv. Imperial ranked first for sensory quality attributes by scoring 26.6 aggregate sensory scores out of 30. Further, among all the cultivars studied Sangria and Salvadore were found superior to grow in soil whereas cultivars Intense and Silvester were found suitable to grow in cocopeat filled growbags however, growbag culture has to be standardized before recommending to the farming community.
