Application of Organic Amendments for Management of Rice Root Knot Nematode

Abstract

A pot experiment was conducted to manage plant parasitic nematode, Meloidogyne graminicola of rice with organic amendments at the Institute of Agriculture and Animal Science, Rampur, Chitwan in 2001 AD. The experiment was carried out in a completely randomized block design with 5 replications. The treatments imposed were plastic pots with 3 kg of naturally infested soil with M. graminicola well mixed with 2.3 kg each of chopped green leaves of malabar, neem, Persian lilac and sissoo, chicken manure and mustard cake and the control pots only with infested soil. Fifteen days old seedlings (cv. Chaite-4) raised in sterilized soil were transplanted per pot and placed in a glasshouse. There was no significant difference in plant height, tiller number, fresh root weight and root length among the treatments. Root knot index was significantly the lowest (2.2) from Persian lilac leaf treatment in comparison to control (3.4). The second lowest value (2.4) was found from malabar and neem leaf treatments. Considerable differences were not observed in population of second stage juveniles in soil and roots and egg numbers in roots among the treatments.
