Correlation between some edaphic factors and Meloidogyne incognlta infestation of mulberry in Malda, West Bengal

Though the root-knot nematode disease is ubiquitous in West Bengal, the disease seems to turn up more often in the mulberry fields of Malda than in other places. This localised population pattern of nematodes favours existence of a close tie between some edaphic factors favourable for growth of nematodes, with it. The present paper establishes the conspicuous correlation between some edaphic factors and their role in nematode infestation.
