Interspecific Competition on Peanut (Arachis Hypogaea L.) Population as Intercropping and Weed Control on Corn (Zea Mays L.)

The experiment conducted to study interspecific competition of corn and peanut as intercropping in intercropping system. The research conducted from April 2013 to July 2013. The experimental design of the research was Split Plots Design (SPD). Numbers of row for the peanut as the main plot (MP) by 3 levels and weed control method as the as the son plot (SP) by 4 levels and as well as monoculture of corn and peanut. Results of the research showed that intercropping system using corn and peanut has not given significant influence on all components yields of corn. Meanwhile, peanut has significant influence on yields of peanut. Result of the analysis on interspecific competition between corn and peanut showed that corn was more dominant and competitive.
