Evaluation of different turfgrass genotypes for growth and physiological parameters under the hilly zone of Karnataka

An investigation was carried out to evaluate different turfgrass genotypes for growth and physiological parameters under the hilly zone of Karnataka was carried out at College of Horticulture, Sirsi (UHS, Bagalkote) during the year 2019-20. Among different genotypes earliest to new growth appearance (6.00 days), longest stolon at 60 days after planting and longest root length (18.23 cm) was observed in Cynodon dactylon L. (STGC-4). Shortest leaf and highest chlorophyll content was recorded in Cynodon dactylon L (STGC-5). Highest number of leaves at 60 days after planting was recorded in Eremochloa ophiuroides. Higher number of roots per culm were recorded in Cynodon genotypes. Pennisetum clandestinum recorded highest shoot fresh and dry weight at complete stage of establishment. The Cynodon genotypes were found to be most suitable under the hill zone of Karnataka.
