摘要： A pot study was performed under greenhouse condition to check the possibility that using Trichoderma harzianum could improve the growth, production and quality of watermelon genotype. Plant growth medium inoculated with T. harzianum at 1 x 10(4) cfu, 1.25 x 10(4) cfu and 1.50 x 10(4) cfu respectively, while un-inoculated with fungi used as control treatment. Plant growth medium inoculated with higher concentration (1.50 x 10(4) cfu) of T. harzianum significantly increased plant root and shoot length and brings early flowering. The higher values of plant fresh and dry weight, leaf area, stomatal conductance, transpiration rate, net photosynthesis rate and number of fruit per plant of watermelon was obtained with 1.50 x 10(4) cfu. However, T. harzianum levels of 1.50 x 10(4) cfu and 1.25 x 10(4) cfu produced statistically similar results for carbohydrate content, total soluble solids, vitamin A content and beta-carotene of watermelon. It was observed that plant grown in growth medium inoculated with T. harzianum has direct relation with growth and quality of watermelon. Compared to all tested levels, the higher level of T. harzianum 1.5 x 10(4) cfu is the most effective in improving growth, yield and quality of watermelon genotype (cv. Sugar baby).
