Effect of Agrosol Treatment and Phosphorus Levels on Pea Plants (Pisum Sativum L.)

Two field experiments were conducted to evaluate the effects of phosphorus level and Agrosol treatment on pea (Pisum sativum L.) yield quantity and quality, under drip irrigation system, during 2012 and 2013 seasons. Experiments were carried out in the Research and Production Station, National Research Centre, El-Nobaria Site, Beheara Governorate, Delta Egypt. Phosphorus fertilizer was applied at rates of 0, 40, 80 and 120 kgP2O5 habefore planted and Agrosol at three levels (0, 2, 4 and 6 mg L) as foliar spray. Plants were sprayed two times with Agrosol in intervals of 30 and 45 days from sowing. The obtained results could be summarized in the following: Growth and yield parameters were significantly increased by increasing phosphorus levels. Dry weight, weight of 100 seeds and yield were significantly increased by increasing of Agrosol levels. The combination between phosphorus at 80 kg P2O5 ha and Agrosol at rate 6 mg L gave the highest growth and production as well as minerals composition (N, P, K, Fe, Mn, Zn and Cu) and protein content compared to other treatments. Agrosol fertilizer decreased soil pH and increased the availability of phosphors and micronutrients.
