Effect of different levels of moisture on the interaction of Glomus fasciculatum with Meloidogyne incognita on cowpea

The pot culture experiment was conducted with different levels of moisture (ranged from 20 to 100%) to study its effect on the interaction af Glomus fasciculatum with Meloidogyne incognita on cowpea and found that maximum growth of the plant was observed at 70% moisture level and increasing level declined the growth of the plant whereas reverse trend was noticed in the root weight character. The nematode population was positively correlated with the moisture level whereas VAM spore population and colonization was negatively correlated with the moisture levels.
