Two field experiments were carried out at the newly reclaimed soils in Khatatba, Giza Governorate during the winter seasons of 2003 and 2004 to study the response of pea plant to different sources of phosphorus and potassium fertilizers (chemical and/or natural) were addition alone or mixture. The characters of pea plant growth as expressed by length, average leaves and stem numbers, leaf area plant as well as the fresh and dry weight of stem, all of them had their peaks with addition mixture phosphorus and potassium fertilizers compared with either alone. The response of the total pigments content, number of pods/plant, weight of pods per plot (kg), weight of 100 seeds as well as the green seeds tissues in the elemental values of P and K to the mixture phosphorus and potassium fertilizers addition followed the same pattern of change as the plant growth. All parameters of plant growth, total leaf pigment contents, total yield and yield components as well as the chemical composition of green pea seeds tissues recorded the highest significant values with applying the chemical sources of phosphorus and potassium fertilizers addition compared with the natural source.
