Cardamom
 
Improved varieties
  • Two high yielding cardamom varieties namely, CCS-1 and RR-1 were released. CCS-1 is a selection from Cl.37 and is characterized by high yield (745 kg (dry capsules)/ha), high quality and is suitable for high density planting. RR-1 is a high yielding variety (848 kg (dry capsules)/ha) resistant to rhizome rot disease.
Propagation
  • Techniques for rapid clonal propagation of cardamom through suckers (trench method) with a multiplication ratio of 1:20 per annum and micropropagation were developed.
Cropping system
  • The trench system of planting at a spacing of 2 m x 1 m was optimum for obtaining higher yields.
  • Mixed cropping of cardamom with coffee, black pepper, arecanut and coconut were found economically feasible and recommended for increasing the productivity from unit area of land.
Nutrient and water requirements
  • Fertilizer schedules for obtaining optimum yields in cardamom were developed.
  • Irrigation schedules during summer through sprinkler systems were developed.
Pest and disease management
  • An integrated disease management strategy involving rouging of affected plants and replanting with disease free material was developed for the management of katte disease.
  • Technologies for integrated management of soil borne diseases namely, rhizome rot and damping off and plant parasitic nematodes, involving solarization of seed beds, phytosanitation, cultural methods, biocontrol agents and chemicals were developed.
  • Integrated management schedules involving regulation of shade, removal of alternate host plants and spraying insecticides were developed for the management of thrips in cardamom.
