| Abstract | ||||
| Two field experiments were carried out at El-Orman Village, El-Sinbelaween Station, Dakahlia Governorate, during the two successive summer seasons of 2010 and 2011. The main objectives of this study were to determine the effect of organic fertilization (without, farmyard manure {FYM} 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 growth characters of maize (Zea mays L.) hybrid TWC 324. Each organic fertilization treatment was performed in separate experiment. Every experiment of organic fertilization treatment was carried out in split plot design with four replications. The obvious results of this investigation can be summarized as follows: All studied growth characters were exerted significant effect as a result of applying organic fertilization treatments in both seasons, except specific leaf area at 50 days from sowing in the first season. 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, exclusion specific leaf area at 50 and 70 days from sowing in both seasons. Whilst, application of Crystal Nasr came in the second rank in this respect in both seasons. On the other hand, the lowest values of all growth 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 parameters in both seasons. Finally, the preferable growth characters 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. | ||||
