The experimental field, which naturally has been known for the presence of some nematodes such as <em>Pratylenchus<\/em>, <em>Helicitylenchus<\/em>, <em>Radopholus<\/em>, <em>Meloidogyne<\/em>, <em>Rotylenchulus<\/em>, <em>Xyphinema<\/em>, 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 <em>Meloidogyne incognita<\/em> galled roots of <em>Celosia agentea <\/em>from a pure culture into all the plots. One block was treated with bio-control agent <em>Trichoderma harzianum<\/em>T<sub>22<\/sub> 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 <em>Trichoderma <\/em>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 <em>Trichoderma harzianum<\/em>T<sub>22<\/sub> improves the yield growth and the yield of soybean as well as better controls soil nematode populations with respect to the control trials.<\/p>\n<p><em>Keywords: Trichoderma harzianum<\/em>T<sub>22<\/sub>, <em>Glycine max<\/em> L., <em>Meloidogyne incognita<\/em>, resistance, susceptible<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Efficacy of Trichoderma harzianumT22 as a biocontrol agent against root-knot nematode (Meloidogyne incognita) on some soybean varieties Nkechi Betsy Izuogu*, T.O.
