PKM 1, bitter gourd (Momordica charantia) cv. CO 1, cluster beans cv. Pusa, swordbeans (Canavalia gladiata) cv. Local and cowpeas cv. CO 1 were assessed when intercropped with Eucalyptus tereticornis and Casuarina equisetifolia. Six-month-old seedlings of the tree species were planted at 4 X 1 m spacing and the intercrops were sown between them. The growing of intercrops did not influence the growth of the tree species, but vegetable yields declined from 3.92 t/ha to 0.014 t/ha in Eucalyptus tereticornis plots and from 4.96 t/ha to 0.089 t/ha in Casuarina equisetifolia. Eucalyptus tereticornis proved more inhibitory to crops than Casuarina equisetifolia. Swordbean was found most suitable for intercropping with both tree species. Bioassays revealed that germination and root and shoot length of the intercrops were suppressed by Eucalyptus tereticornis bark leachate. Leachates of Eucalyptus tereticornis proved more inhibitory to the germination of test crops than Casuarina equisetifolia. 收起
