Intervention effect Jeevamrutha increased growth of legumes by 38.48% compared with the control in nursery conditions.
Intervention effect Jeevamrutha increased growth of non-leguminous trees by 18.50% compared with the control in nursery conditions.
Intervention effect Jeevamrutha had the highest effectiveness among the organic amendments tested.
Intervention effect The microbial consortium was the second most effective organic amendment.
Observation EC of the nursery soil increased from 175 to 620 µS/cm under the organic amendments.
Observation Organic carbon of the nursery soil increased to 1.16% under the organic amendments.
Intervention effect P. pinnata showed the most favourable response to the organic amendments in nursery conditions.
Recommendation Jeevamrutha is a sustainable, high precision alternative to conventional FYM in nursery management.
Recommendation Implementing these organic strategies into practice may greatly improve the long-term productivity and quality of seedlings.
