  1. Control (2 pots), set-1, 2 and 3 are replicates of three pots, and each set is the mean average of three seedlings/pot. Control—addition of only water (pots 1 and 2)
  2. Set-1 contained only chitinase:organic manure formulation (pots 3, 4 and 5)
  3. Set-2 contained chitinase:organic manure formulation as well as 10 ml of inoculum volume of nematodal suspension added near roots of plant (pots 6, 7, and 8)
  4. Set-3 contained fenamiphos: organic manure formulation as well as 10 ml of inoculum volume of nematode suspension added near the roots of the plant at the beginning of the experiment (pots 9, 10, and 11)
  5. Statistical analysis results showed values with the same letters (a, b, c, d, e, f, g) within the column were not significantly different and values with different letters within the column were significantly different from each other according to Duncan’s test
