Intercropping—Evaluating the Advantages to Broadacre Systems

Intercropping is considered by its advocates to be a sustainable, environmentally sound, and economically advantageous cropping system. systems are complex, with non-uniform competition between the component species within cycle, typically leading unequal relative yields making evaluation difficult. This paper review of main existing metrics used in scientific literature assess intercropping systems. Their strengths limitations discussed. Robust for characterising proposed. A major limitation that current assume same management level monocropping do not consider differences costs production. Another drawback they crops mixture equal value. Moreover, employing metrics, many studies have direct private benefits only, ignoring indirect social per se. Furthermore, production risk growers’ preferences were often overlooked. In evaluating advantage using data from field trials, four recommended collectively take into account all important systems, specifically Land Equivalent Ratio, Yield Value Ratio Net Gross Margin.
