Abstract: Competitive behaviour of intercrops in different brinjal based intercropping systems under the Gangetic alluvial zone of West Bengal was investigated in a field study conducted for two consecutive years. Field experiments was carried out with 7 treatments [T₁ (Sole Brinjal), T₂ (Brinjal + Cowpea), T₃ (Brinjal + Garlic), T₄ (Brinjal + Fenugreek), T₅ (Brinjal + Onion), T₆ (Brinjal + Coriander), T₇ (Brinjal + French bean)] following randomized block design with three replications. The results indicated that maximum production efficiency was observed in brinjal + French bean (222.78 kg/ha/day). Intercropping of brinjal with French bean was found promising for better utilization of biological resources as it recorded maximum values for LER (2.68), and desirable lower values of aggressivity (0.15). However, brinjal + cowpea was found maximum for RCC (2.49), and brinjal + onion had maximum monetary advantage index (208.29).
