Indian Journal of Nematology

Two pot experiments were conducted under screen house condition in Department of Nematology, CCSHAU, Hisar. In first experiment, 5 kg capacity earthen pots filled with H. avenae infested soil in which wheat was rotated with fallow, resistant and susceptible wheat, gram, fenugreek, mustard, cabbage, garlic and onion for one season (2015–16). In the next year, susceptible wheat was sown in each pot and after harvest nematode population was recorded. Results revealed that rotation with all the crops, except susceptible wheat reduced nematode population. Crop rotation with gram and fenugreek improved maximum soil health but rotation with mustard reduced maximum nematode population as well as maintained soil heath in terms of nutrients status like N, P, K and Zn. In second experiment, penetration and development of cereal cyst nematode was observed in rotational crops. Results found that among rotational crops maximum number of juveniles was observed in susceptible wheat followed by resistant wheat. More number of males developed in resistant wheat.
