A study looked at how different levels of water and planting combinations affect the growth, yield, and profits of pigeonpea crops under drip irrigation. They found that using 75% of the recommended water amount led to the best results, with higher plant growth and yields compared to using less or more water. Planting only pigeonpea without other crops gave the highest growth and yield, but planting pigeonpea with greengram gave the most profit. Overall, using the right amount of water and choosing the right planting combination can help farmers grow healthier crops and make more money.
