dc.description.abstractGerbera (Gerbera jamesonii L.) commonly known Transvaal daisy is an important commercial cut flower crop. Gerbera flower stalks are long, thin and leafless and have a long vase life. Experiment was conducted to determine the impact of different fertigation levels on growth and flower production in Gerbera (Gerbera jamesonii L.). Five fertigation levels i.e., T1 to T5 (60, 80, 100, 120 and 140% of commercial fertigation schedule) and four varieties V1 to V4 (1654, Livia, Haimi and Petali) were used to conduct the trial. Quarterly observations were recorded on multiple traits. In the month of June, treatment T4 had the maximum plant height, plant spread, number of leaves, leaf area and SPAD value. Treatment T3 caused early flower bud opening with larger flowers, longer stalk length, higher flower yield and more vase life. In varieties, V4 had the maximum plant spread, leaf area and SPAD value while V3 had maximum flower diameter, stalk length and disc diameter. Number of flowers per plant and vase life was maximum in V2. In the subsequent quarters i.e., September, December and March, fertigation treatment T3 recorded highest plant height, plant spread, leaf area, SPAD value, early flower bud opening, flower diameter, stalk length, number of flowers and vase life. Amongst varieties, V4 had higher plant height, plant spread, leaf count and flowers, whereas, V2 had shown early flower bud opening, maximum flower diameter, flowering duration and vase life. So, to conclude, fertigation treatment, T3 (100% of commercial fertigation schedule) caused significant improvement in the plant growth and flower production which was statistically at par with treatment T4 (120% of commercial fertigation schedule). Variety V4 (Petali) performed best in terms of flower production and vase life that was statistically at par with V2 (Livia).
