4.1.4.5 Effect on plant fresh and dry weight of RKN free plants

The data indicated significant increase in plant fresh weight by endophytic fungi treatments, most effective treatments were Nigrospora sp, isolate XP 9 and Trichoderma pseudokoningii, with significant mean plant fresh weight of 134.33 g, 131.33 g and 130.00 g respectively in that order, least mean plant fresh weights were observed in treatments with Fusarium sp3 and Ulocladium sp, that is 70.08 g and 69.17 g respectively Table 10. The data also indicated significant increase in plant dry weight, most effective treatments were Nigrospora sp, isolate XP 9 and Trichoderma pseudokoningii with the highest mean dry weight of 43.91 g, 41.50 g. and 41.33 g, respectively in that order, least dry weights were observed in treatments with Fusarium sp3 and Ulocladium sp, that is 18.67 cm and 15.67 g respectively Table 10.

4.1.4.6 Effect on number of fruits and root length RKN free plants

The data on mean number of fruits indicated higher significant increase in number of fruits by Nigrospora sp, isolate XP 9, Trichoderma pseudokoningii, Trichoderma hamatum, and Chrysosporium sp with mean number of fruits 42 of 12.42, 12.42, 12.25, 12.00 and 11.83 respectively in that order, least mean number of fruits were observed in treatments with Ulocladium sp, and Fusarium sp 3 that is 4.00 and 3.92 respectively. The data also indicates that all endophytic fungi isolates used were highly significant in increasing root length development in comparison to the control treatments, whereby Nigrospora sp, isolate XP 9, Trichoderma pseudokoningii had the highest mean root length of 41.58 cm, 41.00 cm and 39.42 cm respectively, least root length was observed in treatments with Ulocladium sp, and Fusarium sp3 that is 17.83 cm and 16.25 cm respectively Table 11.
