Abstract
The aim of the study was to out whether the beneficial effect of T. harzianum in enhancing maize seed germination and seedling growth under water stress is dependent on the maize variety soil samples were collected from Marigat Rangeland, Kenya. Trichoderma harzianum was isolated using macro and micro-morphological characteristics. The present study employed a three-factor factorial (3 x 2 x 2) design, arranged in a completely randomized design (CRD) with three replications. There was no significant (p > 0.05) difference in percentage germination, seedling length, fresh weight, shoot-root dry weight, superoxide dismutase and catalase activities among the three varieties of maize. In addition, significant differences in seed germinations, seedling growth parameters and antioxidant enzyme enzymes were recorded between treated and control plants among the three varieties of maize. Maize variety had no significant influence on the beneficial activity of T. harzianum.
