Abstract
Advantages in coconut and arecanut based mixed cropping systems are studied using Land Equivalent Ratio (LER), Monetary Advantage (MA), Aggressivity Index (A) and Competition Ratio (CR). Under the irrigated system, arecanut and cacao combination gave a monetary advantage of Rs. 19,193 per ha per year with an LER of 2.18. Arecanut and pepper combination gave a monetary advantage of Rs. 18,402 per ha per year with an LER of 1.50. Coconut and cacao combination recorded a monetary advantage of Rs. 14,920 per ha per year with an LER of 1.46. Under rainfed system, coconut and ginger gave a monetary advantage of Rs. 29,683 per ha per year with a corresponding LER of 1.56. Coconut and turmeric recorded a monetary advantage of Rs. 16,483 per ha per year with an LER of 1.41.
