| Abstract | ||||
| Maize and wheat are the most important cereal crops in Egypt. A field experiment was carried out at the Noubaria Farm Agricultural Research Station during summer 2009 followed by winter 2009/2010 for maize and wheat, respectively. This study was conducted to evaluate the impacts of the integrated individual use of sole mineral NPK fertilizers, or combinations of either single type or various mixtures of NPK and compost types. The standard different fertilization treatments were rates of 75% or 100% (as a recommended dose by the Ministry of Agriculture and Land Reclamation (Egypt). Maize was grown single cross 10 to study the effect of these treatments and their residual effect on followed wheat (C.V. Sakha 93). The results could be summarized as those due to the case of the above mentioned rates of 100% and 75%. However, the application of 100% (NPK) and compost were indicated a better yield of maize grain, stover, wheat grain and straw. Moreover, this preferable rate 100% has left higher availability percentages of macronutrients in both cases of maize and wheat, as compared to rate of 75%. Significant increase of all parameters i.e., grain and stover yields, macronutrients content and the availability of macronutrients for maize soil, were achieved by the application of the mineral NPK solely. While lower values of this parameters, were recorded when applying any single compost types. On the other hand, the trend for residual effect and the resulting availability of macronutrient content of wheat grains, and straw was greatly enhanced by the addition of any organic manures. Interaction between factors under study, shows that the complementary organic and inorganic fertilizers under the high level was more effective than individual application of either organic or mineral (NPK) fertilizers alone for macronutrients content of maize and wheat grains, as well as in soil after harvesting both crops. | ||||
