Preliminary studies on the effect of organic manure in the control of root-knot nematode, Meloidgyne incognita and growth of okra and tomato in South western Nigeria,

The relevance of poultry and pig manure a d their combination as nematode suppressant on tomato and okra were studied. The organic amendments were worked into the soil just before sowing of okra seeds or transplanting tomato seedlings the rate of 16t/ha-1 each, their combination in equal proportion of 8t/ha-1 while plots treated with mocap (nematicide) at the rate of 3g a.i. per plant served as control. The effect of nematicide on nematode soil population was not different from poultry manure. Similarly, plants treated with nematicide or poultry manure recorded significant vegetative and reproductive growth when compared with other variables. The implication of the result is discussed.
