The researchers compared different ways of growing pigeonpea crops to see which one was the most effective. They found that growing pigeonpea with wheat gave the highest amount of total plant yield and grain yield. This method also made the most profit compared to other ways of growing pigeonpea. However, another method called pigeonpea-ratoon (cutting) had the highest benefit compared to cost. Overall, growing pigeonpea with wheat was the best for getting the most yield and profit, while pigeonpea-ratoon (cutting) was the most cost-effective.
