Abstract

Among the different biotic stress, plant parasitic nematodes are considered to be real menace to successful and profitable cultivation of crops. This tiny microscopic organism can effectively manage by application of chemical pesticides, but frequent use of chemical pesticides may induce residual effect, phytotoxicity, health hazards to human and live stocks including ground water contamination. To overcome these hazards, effort is being made to reduce the nematode infestation by some non chemical methods. Use of proper crop sequences seems to be one of the best methods to counter nematode problem. Incorporation of non host or poor host crop between two susceptible host crops can successfully reduce nematode infestation. In the present study four crop rotation sequences were tested for their efficacy to reduce the incidence of plant parasitic nematodes on jute in a naturally infested field of Biswanth College of Agriculture, Biswanath Chariali, Assam during 2019–20. Other ecofriendly nematode management practices like application of compost and crop residue, soil incorporation of dhaincha as green manure, application of bioagents were also combined with different crop sequence. Among the different crop sequences, Jute-Toria-Dhaincha-Jute was found to be most effective in reducing the final nematode population in soil and increasing the seed yield of jute followed in order of efficacy by the crop sequence Jute-Toria- Fallow- Jute. These crop sequences may be recommended for future record.
