The researchers studied how growing maize with other crops affects maize yield and weeds in rainy conditions. They found that intercropping maize with other plants reduced maize yield, but increased overall productivity and reduced weed growth. Maize + turmeric had the highest productivity, while maize + sesame had the lowest. Maize + forage meth had the best weed control, while maize + pigeonpea had the worst. Intercropping can help increase overall productivity and control weeds in maize fields.
