Competition Functions of Different Canola-Based Intercropping Systems

Muhammad Tahir, Muhammad Asghar Malik, Asif Tanveer and Rashid Ahmad


Competition functions of different intercropping systems i.e. canola, wheat gram, lentil and linseed were compared with sole cropping of canola for two consecutive years under the field conditions. Competition behaviour of component crops across different intercropping systems and planting patterns was determined in terms of relative crowding coefficient, aggressivity and competitive ratio. Relative crowding coefficient (RCC) reflected that maximum K (4.08) was obtained from canola+one row of wheat intercropping system. Aggressivity (A) values –0.03 and 0.06 indicated that wheat was the most competitive crop to canola. Similarly, competitive ratio (CR) 0.82 and 0.51 showed that among intercrops, wheat proved to be a better competitor than other intercrops when grown in association with canola.
