Abstract:
Biochar is a carbon rich product being used in production of many horticultural crops; the production of quality planting material is the key to enhance the yield and quality of the crops. The study on use of biochar for the production of quality seedlings of jackfruit was undertaken with view of minimizing the cost of production of seedlings in eight treatments with three replication. The application of soil, sand and organic biochar in the ratio of 2:1:1 to a rooting media was found to enhance the germination percentage (100%), rate of germination (1.63) and seedling vigour (3667). The growth attributes such as seedling height (64.67 cm), girth (8.07 mm), number of leaves (7.13), leaf area (123.44 cm²) and root attributes like root length (31.67 cm), root volume (18.30 ml) and root biomass (18.0 g) at 120 days after germination was found to be maximum in T₂. The benefit cost ratio (1.97:1) was observed maximum in same potting mixture.
