| Abstract | ||
| The study aimed to investigate the effect of extracts and powders of plant parts for the yellow melilot on lengths and fresh weights of wheat which planted in incoulated soil with Rhizoctonia solani Kuhn (R.s.1and R.s.2), it was found that the shoot extract inhibited their plant height, to 15.5, 18, 15.5 and 11.5 cm in the 10, 20, 40 and 80% concentrations, respectively compared with 30.7 cm in control treatment. The root extracts increased the shoot lengths of the plants at 40% concentration, to 35.5 cm compared with 30.7 cm in control treatment, while it reduced to 23.3 cm compared at 80% concentration. Also the shoot extract yellow melilot decreased the weight of wheat plants to 23.6 mg at 80% concentration compared with 150 mg in control treatment. The study showed that the root extracts of yellow melilot promoted the soft weights of wheat plants to 188.3 and 215.6 mg in 10 and 40% concentration, respectively, compared with 150 mg in control treatment. The inoculated soil with R.s.1 and mixed with seed and shoot of yellow melilot caused inhibition of the growth of wheat plants which was reflected on the lengths and soft weights of wheat plants so the less growth of lengths and weights for wheat plants were in (soil + seed powder + sterilized millet seeds) treatment ( 0.617 cm and 5.00 mg) compared with(10.217cm and 54.33mg) in the soil only treatment respectively, while the inoculated soil R.s.2 and mixed with root powder of yellow melilot increased the wheat growth The highest lengths and soft weights appeared in the (soil + root powder + R.s.2 + sterilized millet seeds) which were (20.25 cm and 267.77 mg) compared with(10.58 cm and 92.83 mg) respectively in the soil only treatment. | ||
