Growth, productivity and quality of eight vegetable crops grown in four crop sequences, viz., potato-onion, tomato-cowpea, fababean-colocasia and french bean-turmeric in young eucalyptus plantation were studied. The plant height of potato, cowpea and turmeric showed an increase, while that of tomato, fababean, french bean and colocasia showed a declining trend under the effect of eucalyptus shading. The average leaf area, number of leaves and dry matter content/plant were drastically reduced in almost all the crops. The number of daughter rhizomes in colocasia and turmeric, pods/plant in all the beans and yield of all the intercrops decreased substantially as compared to open environment. The production of A and B grade tubers in potato and bulbs in onion was not satisfactory under shade. The most deleterious effect of shade was observed in onion while turmeric showed minimum yield loss due to shade.
