abstract
An experiment was conducted to evaluate efficacy of organic amendments such as neem cake, mustard cake, caster cake @ 5g and 10g per kg of soil against the rice root-knot nematode, Meloidogyne graminicola in rice nursery. The treatments were replicated three times in a randomized complete block design. For comparison, one set without nematode was also kept. Carbofuran and the cakes were well mixed in soil and filled in the two kg earthen pots. 25 Seeds of rice var. Pusa 1121 were sown in pots. The recommended doses of fertilizers were used in each pot at the time of sowing. Observations on plant growth parameters and nematode reproduction were recorded 45 days after sowing. Data indicated that castor cake @ 10 g/kg soil was found best in improving plant growth and reducing nematode galls and reproduction.
