Maize is well known for its high demand for nutrients and other production inputs. Thereby, two field experiments were carried out at El-Orman Village, El-Sinbelaween Station, Dakahlia Governorate, Egypt, during 2010 and 2011 seasons to determine the effect of organic fertilization (without, farmyard manure and compost) and foliar fertilization (without, spraying with water, Crystal Nasr and Melagrow) under nitrogen fertilizer levels (50, 75 and 100 kg N/fed) on productivity of maize hybrid TWC 324. All studied growth characters were exerted significant effect as a result of applying organic fertilization treatments in both seasons. The treatment from organic fertilization which gave the highest values of these characters was applying the compost as compared with other treatments in both seasons. Foliar application with Melagrow as a natural growth promoter significantly recorded the highest values of studied growth, yield and its attributes in both seasons. Whilst, application of Crystal Nasr came in the second rank in this respect in the two seasons. While, lowest values of all growth, yield and its attributes characters were resulted from the control treatment (without foliar application) in both seasons. Application nitrogen fertilization at the level of 100 kg N/fed significantly exceeded other levels (50 and 75 kg N/fed) of studied growth, yield and its attributes parameters in both seasons. The preferable productivity of maize hybrid TWC 324 can be achieved through organic fertilizing with compost, foliar application with Melagrow and mineral fertilizing with 100 kg N/fed under the environmental conditions of El-Sinbelaween Center, Dakahlia Governorate, Egypt.
