Sažetak
In 2012 and 2013, a two-year field study was conducted at the University of Ilorin Teaching and Research Farm, Ilorin, the Southern Guinea Savannah Zone, Nigeria, with the aim to investigate the effect of Trichoderma harzianumT22 as a bio-control agent against a root-knot nematode (Meloidogyne incognita) on some soybean varieties. The experimental field, which naturally has been known for the presence of some nematodes such as Pratylenchus, Helicitylenchus, Radopholus, Meloidogyne, Rotylenchulus, Xyphinema, was divided into two blocks, each block consisting of three plots with alleys between blocks and plots measuring 5 m and 1.5 m respectively. All treatments were replicated five times by means of a Randomized Complete Block Design. The initial soil nematode population was increased by chopping six kilograms of Meloidogyne incognita galled roots of Celosia agentea from a pure culture into all the plots. One block was treated with bio-control agent Trichoderma harzianumT22 while the second block served as a control unit. The results show that in terms of plant height, the number of branches, yield and reduction of the soil nematode population and root galls, the plants on the Trichoderma treated plots performed significantly better (P=0.05) than those in the control unit did. This therefore implies that root-knot nematodes represent a major constraint in the production of soybean while Trichoderma harzianumT22 improves the yield growth and the yield of soybean as well as better controls soil nematode populations with respect to the control trials.
