A study was undertaken to develop a model for forecasting the yield of cardamom under intensive management. Thirteen biometrical characters namely number of tillers per clump, tiller height, number of leaves per tiller, number of vegetative buds per clump, number of bearing tillers per clump, number of panicles per clump, panicle length, number of racemes per panicle, number of capsules per raceme, number of seeds per capsule, leaf length, leaf breadth and recovery percentage comprised the variables examined and they exhibited a precision of about 82%. Step down regression resulted in the retention of only four characters namely, number of panicles per clump, number of racemes per panicle, number of capsules per raceme and leaf breadth with which yield can be estimated with 77% precision.
