| Abstract | ||
| Two field experiments were conducted to study the effect of different rates of biofertilizer (Phosphorein) combined with different levels of phosphorus on mung bean plants. Using phosphorein with the rates of 200, 300 and 400 (g) I feddan in combination with 15.50,23.25 and 31.00 kg P20slfed. promated the vegetative growth and seed yield of mung bean plants. The highest values of main stem length, number of branches, total leaf area, dry weight of shoot and seed yield plant, were obtained when the combination between 200 (g)/ feddan of phosphorein and 23.25 kg P20sl feddan was used. The vigor of vegetative growth recorded due to phosphorein application at the rate of 200 g/fed. in combination with 23.25 kg P20s and accompanied with increasing in amounts of different tissues of stem and leaf specially the vascular tissues. High values of N, P and K concentrations in both shoots and seeds as well as chlorophyll a and b in the leaves and protein % in the seeds were recorded by the plants treated by any of the three different rates of biofertilizer phosphorein either alone or when combined with any of the three different rates of phosphorus fertilization if compared with corresponding plants untreated with biofertilizer. However, a reverse trend was obtained in total carotenoids by the same treatments. | ||
