| Abstract | ||
| This investigation was conducted during two successive seasons (2005/2006 and 2006/2007) on the first and second ratoons of Williams banana plants grown in a sand clay loam soil under flood irrigation conditions in a banana orchard located at El-Kanater Research Station, Kalubia Governorate. The plants received recommended dose (RD) of mineral N only/or between its different rates (75, 50 and 0% N of RD) and organic N in the form of Nile Compost (NC) and Chicken Manure (CM) as well as Microbein bio-fertilizer (M). The obtained results clarified that all used treatments were effective in improving growth, yield and fruit quality in comparison with 100 % N either in the form mineral (control) or in the form organic manure (Nile Compost or Chicken Manure) of Williams banana. It was also noticed that the combined treatment of 50 % mineral N + 50% N in the form of compost with Microbein biofertilizer gave best plant vegetative growth parameters (circumference and height of pseudostem, number of green leaves and leaf area( as well as leaf chemical content expressed as an increase in percentages of nitrogen, phosphorus and potassium. In addition, it noticed that the same combined treatment had the highest values of yield and its components such as bunch weight, number of hands/bunch, average hand weight and number of fingers/hand. Also, it noticed that the same combined treatment improved physical properties of fruits expressed as average finger weight, average finger length, average finger diameter and pulp (%) as well as chemical properties of fruits such as, increasing the percentages of TSS, reducing and total sugars while decreased the percentage of acidity. In general, the results proved that using of 50 % mineral N + 50% N in the form of compost + Microbein biofertilizer are the most superior treatments for increasing vegetative growth, yield and its components as well as fruit quality of Williams banana. Hence, It could be concluded that, minimizing the use of chemical nitrogen fertilizer to half of recommended dose through addition of 50 % mineral N + 50% N in the form of compost with Microbein biofertilizer. | ||
