Abstract
Seeds of two millet and two pulse crops were germinated under the influence of top soil, rhizosphere soil, soil mulched with dry leaves and green leaves leachate of O. dalbergioides and also in the aqueous extracts of its green leaves, leaf litter and bark. Presence of tree components in the germination medium substantially suppressed the germinability of crop seeds but the magnitude of inhibition varied with the crop as well as tree component. Overall, irrespective of the test crops, rhizosphere soil and aqueous extract of green leaves caused considerable reduction in germination. Not only the final percentage of germination was reduced but the germination was delayed also.
