Abstract
An experiment was conducted to evaluate the performance ginger genotypes under coconut ecosystem at Coconut Research Station, Aliyar Nagar, Tamil Nadu Agricultural University, and Coimbatore during the period from 2017- 18and 2018-19. The experiment was laid out in Randomized Block Design (RBD) with three replications and the treatments included viz., Rejetha, Ashwathy, Maran, Karthika, GCP 49, IISR 1 (GB), Mahima, ACC 578, Athira, ACC 581, Rio de Janeiro, Varadha, Thadimaram and local Gudalore. data were recorded from five randomly selected plants on plant height, shoot diameter, number of shoots, number of leaves, leaf length, leaf breadth, yield per plot and hectare and was analyzed using analysis of variance. Results showed the highest plant height (92.70 cm),shoot diameter (3.27cm), no. of leaves (30), leaf length (27.89 cm) registered in Thadimaram, whereas the highest no. of shoots (8.10), leaf width (3.78 cm), yield per plot (13.64 kg) and yield (24.80t/ha) was recorded in Athira followed by Rejethawhich recorded the highest yield per plot (12.15 kg) and yield (22.09t/ha) during 2017-18.During 2018-19the highest plant height (99.90 cm),shoot diameter (3.60cm), leaf length (29.10 cm) was registered in Thadimaram, whereas the highest no. of shoots (8.30), no. of leaves (36.0), leaf width (3.90 cm), yield per plot (14.20 kg) and yield(25.50 t/ha) was recorded in Athira followed by Rejethawhich recorded the highest yield per plot (12.70kg) and yield (22.80t/ha). Athira and Rejetha genotypes outperformed the other genotypes and could be considered as the most suitable genotypes for cultivation under the coconut ecosystems of Coimbatore district.
