Abstract:
The present investigation entitled” Field performance evaluation of in-vitro raised strawberry cv. Nabila under poly tunnel “was conducted at the “Research Farm of Centre of Excellence on Protected Cultivation and Precision Farming under protected condition, located at College of Agriculture, IGKV, Raipur (C.G.)” during the year 2018-19 and 2019-20 under experiments with 3 replications and is laid out in Randomized Block Design. The effects of different combinations of growth regulators was non significantly affected the plant height at 30-45 DAT and 120 DAT, while it was significantly affected at 0-15, 15-30, 45-60 and 90 DAT. Maximum plant height was record with MS + BAP (1.00 mg/l) + NAA (0.1 mg/l)) at 0-15 DAT, MS + Kinetin (1.00 mg/l) + NAA (0.50 mg/l) at 15-30 DAT, MS + Kinetin (1.00 mg/l) + NAA (0.50 mg/l)) at 45-60 DAT, MS + BAP (1.00 mg/l) + NAA (0.10 mg/l) at 90 DAT and MS + Kinetin (1.00 mg/l) + NAA (0.50 mg/l) at 120 DAT. In E-W direction maximum plant spread was recorded with MS + BAP (0.5 mg /l) + NAA (0.1 mg/l) at 15 DAT, MS + BAP (1.0 mg /l) + NAA (0.5 mg/l) at 30 DAT, MS +BAP (0.5 mg/l) + NAA (0.5 mg/l) at 45 DAT, MS + BAP (1.0 mg/l) + NAA (0.1 mg/l) at 60 DAT, MS + Kinetin (1.0 mg/l) + NAA (0.1 mg/l) at 75 DAT, MS + Kinetin (1.0 mg/l) + NAA (0.1 mg/l) at 90 DAT and MS + Kinetin (1.0 mg/l) + NAA (0.1 mg/l) during both the years of study (2018-19 and 2019-20). In N-S direction maximum plant spread was recorded with MS + Kinetin (1.0 mg/l) + NAA (0.5 mg/l) at 15 DAT, MS + Kinetin (1.0 mg/l) + NAA (0.5 mg/l) at 30 DAT, MS + Kinetin (1.0 mg/l) + NAA (0.1 mg/l) at 45 DAT, MS + Kinetin (1.0 mg/l) + NAA (0.1 mg/l) at 60 DAT, MS + Kinetin (1.0 mg/l) + NAA (0.1 mg/l) at 75 Days after transplanting, MS + Kinetin (1.0 mg/l) + NAA (0.1 mg/l) at 90 Days after transplanting and MS + BAP (1.0 mg/l) + NAA (0.1 mg/l) at 120 Days after transplanting during both the years of study (2018-19 and 2019-20). The work recommended that use of growth regulators along with MS medium can enhance the quality and yield performance of strawberry under in-vitro conditions.
