Abstract: This study was conducted on intercropping of medicinal crops <em>viz</em>., ashwagandha, garden rue, roselle and holy basil with pigeon pea and nipped castor in <em>alfisols </em>of eastern dry zone of Karnataka in <em>kharif</em> 2012. Intercropping of ashwagandha significantly reduced the growth and yield of field crops. The pigeon pea /castor + garden rue system performed better than sole crops of field crops. The yield of medicinal crops reduced due to intercropping. Sole crop of garden ruerecorded significantly higher dry herb yield (1.43 t ha^-1). Sole crop of roselle recorded highest fresh calyx yield (3.37 t ha^-1) followed by pigeon pea intercropping (2.94 t ha^-1) and castor intercropping (2.47 t ha^-1). Pigeon pea + garden rue recorded maximum LER, ATER and net returns of 1.98, 1.82 and ` 29533.00 ha^-1, respectively with a B: C ratio of 0.89.
