Abstract: A field experiment was conducted during two successive crop seasons (maize and pea) in summer 2007 followed by winter 2007/2008 to assess effect of farmyard manure (FYM) or town refuse (TR) applied at a rate of 10 tonne/fed. before maize planting and mineral fertilizers NPK at recommended dose and combination between 50% of NPK at recommended dose combined with soil conditioners, on growth parameters, straw and grain yields and total uptake of N, P, K, Fe, Zn and Mn by straw and grains of maize corp. Also evaluate the residual effect of soil conditioners individual or combined with 50% of recommended dose of mineral fertilizers on pea growth parameters, straw and green seeds and total uptake of macro and micronutrients by straw and green seeds and availability of some nutrients in soil. The results showed that the experimental treatments had a significant effect on the growth parameters, straw, grains and green seeds yields of both maize and pea plants. Also total uptake of nitrogen, phosphorus, potassium, iron, Zinc and manganese by straw and grains of maize and by straw and green seeds of pea plants were enhanced by different treatments. Recommended dose of mineral fertilizers induced highest values of growth parameters, straw and grains and green seeds yields, total macro and micronutrients uptake by straw, grains and green seeds for both maize and pea plants when compared to the other treatments. Among the treatments, FYM+50%NPK and residual FYM+ 50%NPK mineral fertilizers recorded the highest values for the above mentioned parameters and they were significantly better than all other treatments for maize and pea plants, respectively. Application of soil conditioners or mineral fertilizers clearly enhanced the availability of nutrients under investigated soil. The contents of available N, P, K, Fe, Zn and Mn were increased dramatically in plot treatments with FYM or TR, and reduced markedly in mineral fertilizers plot but they still higher compared to the control treatment
