The researchers tested different herbicide combinations on maize plants to see how they affected weed growth, crop yield, and profits. They found that using a mix of Atrazine and Pendimethalin herbicides gave the best results, reducing weeds and increasing maize yield significantly. This combination also led to higher profits compared to other herbicides tested. Overall, the study showed that using specific herbicides can effectively control weeds, boost crop yield, and improve economic returns for maize farmers.
