Evaluation of Forage Quality in Intercropping of Corn and Cowpea Affected by Foliar Application of Urea and Vermicompost

One of the most important elements in forage crop production and management is high forage qualitative. In order to evaluation the effect of urea foliar application and vermicompost fertilizer on forage qualitative in corn (Zea mays L.) – cowpea (Vigna unguiculata L.) mix cropping, an experiment was lay out in RCBD as strip- split plot with four replications in Khorramabad temperate region during 2011- 2012. Urea foliar application and control, using vermicompost fertilizer and control, and corn + cowpea mix cropping (sole corn and sole cowpea, and %75:%25, %50: %50, %25: %75, corn:cowpea) were the factors. Urea foliar application and using vermicompost fertilizer had better performance than controls. The lowest pure fibers and the highest ash, pure protein, amount of forage energy, digestible dry matter, and protein yield were achieved from Urea foliar application and using vermicompost fertilizer and %75:%25 and %50: %50, corn:cowpea mix cropping rates. Results showed that foliar application significantly affected forage quality.
