Intercropping is a farming practice where multiple crops are grown together in the same field. It has been extensively studied in recent years. Researchers have developed over 20 unique indices to compare intercropping with traditional farming practices. Our study collected data from previous intercropping experiments and evaluated those data on the existing indices. We found that the success of intercropping depends on factors such as crop density and ratio, and indices differ in the way that these factors are accounted for. To improve research in this area, it is important to establish a standard protocol for conducting and evaluating intercropping trials. This will ensure that future research is effective and can provide accurate comparisons to traditional farming practices.
