Abstract
Maize and wheat are the most important cereal crops in Egypt. Afield experiment was carried out at the Noubaria Farm AgriculturalResearch Station during summer 2009 followed by winter 2009/2010for maize and wheat, respectively. This study was conducted to evaluatethe impacts of the integrated individual use of sole mineral NPKfertilizers, or combinations of either single type or various mixtures ofNPK and compost types. The standard different fertilization treatmentswere rates of 75% or 100% (as a recommended dose by the Ministry ofAgriculture and Land Reclamation (Egypt). Maize was grown singlecross 10 to study the effect of these treatments and their residual effecton followed wheat (C.V. Sakha 93). The results could be summarized asthose due to the case of the above mentioned rates of 100% and 75%.However, the application of 100% (NPK) and compost were indicated abetter yield of maize grain, stover, wheat grain and straw. Moreover,this preferable rate 100% has left higher availability percentages ofmacronutrients in both cases of maize and wheat, as compared to rate of75%. Significant increase of all parameters i.e., grain and stover yields,macronutrients content and the availability of macronutrients for maizesoil, were achieved by the application of the mineral NPK solely. Whilelower values of this parameters, were recorded when applying anysingle compost types. On the other hand, the trend for residual effectand 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 complementaryorganic and inorganic fertilizers under the high level was more effectivethan individual application of either organic or mineral (NPK) fertilizersalone for macronutrients content of maize and wheat grains, as well asin soil after harvesting both crops.
