| A pot experiments was conducted to study the possible role of melatonin (50 µM or 100 µM) alone or in combination with Basagran herbicide at recommended dose or ½ recommended dose in reducing the deleterious effect of weed associated with Vicia faba plants. Results show that all applied treatments significantly reduced the weed dry weight at 45 DAS and at harvest accompanied by significant increase in growth parameters of bean plants (at 45 DAS), all components of photosynthetic pigments, seed yield/plant and its components relative to unweeded treatment. It is obvious that herbicide at recommended dose was more effective than herbicide at ½ recommended dose. Similarly, melatonin at 50 µM was more effective than melatonin at 100 µM. It is worthy... |
