Potential of Important Agriculture Crops under Medicinal Agroforestry Tree Species in Nagaland, North-east Himalaya, India

Present investigation was conduct to evaluate the effect of three medicinal agroforestry tree species on germination and ischolar_main-shoot growth of different test crops. All the test crops were found sensitive under leaf and bark mulches of all three medicinal tree species except Gylcin max under Azadirachta indica bark mulch and under leaf mulch of Terminalia bellirica, with respect to germination. These medicinal tree species have allelopathic potential and contain water soluble substances. They have inhibitory effect at higher concentration but at low concentration have stimulatory effects. All the tested agricultural crops may be cultivated under Terminalia bellirica with least harm. The importance indexes of medicinal agroforestry tree species was found to be in order: Terminalia bellirica >Azadirachta indica >Emblica officinalis and the order of agriculture field crops indexes is: Glycine max> Zea mays >Brassica campestris> Setaria italica
