| Abstract | ||
| A filed experiment was conducted during summer season ( 2009 ) to study The effect of four levels by organic fertilization ( 0 , 3 , 6 ,9 ) ton / ha and intercropping for Cowpea and Sweet Corn . The Experiment was factorial in R.C.B.D. with three replications . Results showed that significant increases in growth and yield characters when used organic fertilizer was applied at of 9 ton ha and gave highest seed yield for Cowpea and Sweet Corn plant ( 79.35 and 46.33 gm ) respectively . Intercropping for Cowpea and Sweet Corn decreased almost all studied characters , while increased the land Equivalent Ratio ( LER ) and gave 1.64 . The interaction treatment of organic fertilization and single planting for Cowpea or Sweet Corn gave the highest seed yield ( 96.33 and 49.42 gm/plant ) respectively . | ||
