Intercropping maize with soybean or green gram in specific row ratios can increase crop diversity, soil fertility, and farmer livelihood in the North-eastern Hill Region of India. The study found that intercropping maize with soybean in a 1:2 row ratio resulted in the highest maize equivalent yield, system productivity, and production efficiency. On the other hand, intercropping maize with green gram in a 1:2 ratio showed higher land equivalent ratio and land equivalent co-efficient. Overall, intercropping maize with soybean or green gram can be beneficial for farmers in this region.
