The field experiment was conducted on bed planted wheatat the research farm, Department of Agronomy, Punjab Agricultural University, Ludhiana during rabi seasons of 2012-13 and 2013-14 in a split-plot design with four replications. The main plots treatments involved two orientation of sowing i.e. north-south and east-west. Each main plot was divided into five subplots to allocate the intercropping system with wheat, i.e. wheat+spinach, wheat+fenugreek, wheat+oats fodder, wheat+canola and wheat+ linseed along with sole crops. Raising the crop in east-west row orientation resulted in maximum dry matter accumulation, CGR, AGR and RGRas compared to north-south row orientation. Highest values of CGR and AGR were recorded between 60-90 DAS in wheat. Among the intercropping systems, performance of wheat under wheat + spinach and wheat + fenugreek intercropping systems was equivalent to sole wheat. In intercropping systems, canola was found to be more aggressive and competitive to wheat than the other crops.
