Determination of nitrogen and phosphorus fertilizer levels in different maize-faba bean intercropping patterns in Northwestern Ethiopia - Nairobi (Kenya) KARI|CIMMYT : 2002 - p. 513-518 - Printed
A field experiment was undertaken for two years (1999 and 2000) at Adet and Mota experimental stations in northwestern Ethiopia with the objective of determining the appropriate planting pattern and optimum rate of N and p fertilizers for maize-faba bean intercropping. A factorial combination of four nitrogen rates (0.32.64. and 96 kg N/ha). three phosphorus rates (0. 46 and 69 kg P205/ha) and two planting patterns ( 1:1 and 2:1 maize: faba bean alternate row planting) were tested along with two sole crop treatments or maize and faba bean. The experimental design was Randomized Complete Block (RCB) with three replications. The results indicated that there was significant difference in maize grain yield at the two locations due to nitrogen and phosphorus fertilizer levels. Significant difference in faba bean grain yield was observed due to planting pattern. The Land Equivalent Ratio (LER) is more than unity in most or the cases. The highest LERs. 2.0 at Mota and 1.5 at Adet were obtained when a planting pattern of 1:1 maize: faba bean alternate rows were use with the app1ication or 96-46 N- P2 05 kg/ha. The economic analysis has also confirmed that the specified treatment gave the best advantage at all the locations.
