Abstract
Two pot experiments were conducted to assess the effect of cobalt and mycorrhizae (Gigaspora gigantean) mediated phosphorus on the growth and yield of corn as monocots and soybean as dicots. Experiments were carried out at Wire house in National Research Centre, Egypt. Plastic pots (40 cm diameter) filled with silty clay soil and inoculated with mycorrhizae fungi before seeds sowing and fertilized by calcium mono phosphate at 50, 100 and 200 mg P/Kg soil. The seedlings (at the third truly leaf) were irrigated with cobalt sulphate once, with 0, 4, 8, 10, 12, 16 and 20 ppm cobalt. The obtained results can be summarized as follows: The growth of both corn and soybean plants, inoculated with low phosphorus level were significantly increased compared other levels. The mycorrhizae colonies decreased as P increased while cobalt is not significant. Cobalt at 10 ppm with mycorhizae had a significant promotive effect on growth, yield minerals composition and chemical content of corn compared with mycorrhizae alone. Cobalt at 12 ppm with mycorrhizae gave a similar effect of soybean. Phosphorus content of plants was nearly doubled in mycorrhizae and cobalt compared with mycorrhizae alone. It can be concluded that the cobalt with mycorrhizae inoculation under low phosphorus level enhanced the growth, yield quantity and quality in both corn and soybean, but this positive impact was more significant in the dicot plants compared to monocot.
