Abstract:
The present investigation was carried out as an unreplicated observational trial under the All India Coordinated Research Project on Palms at S.G. College of Agriculture and Research Station, Jagdalpur (C.G.) having ten palms per genotype to evaluate the performance of different coconut varieties in Bastar region of Chhattisgarh. The growth parameters revealed the maximum plant height in Kalpa Raksha (670 cm) while the girth at base in Kalpa Mitra (139.0cm). With regard to the other plant growth and yield characters Gautami Ganga revealed to be superior over the other varieties for the maximum number of leaves at crown (18.8), annual leaf production (9.2), age of palm at first flowering (72 months), number of inflorescence (10.1), nut setting percentage (51) and number of harvested nuts (78) over the other varieties. With regard to the tolerance of varieties against insect-pests the minimum infestation of Rhinocerus beetle (%) as well as Rugose spiriling white fly (%) was observed in the variety Kera Bastar (1.5 and 11.6 respectively). While the incidence of Red Palm weevil was the minimum in the variety Kalpa Raksha (1.2%).
