A study was done to see how giving extra water to cotton plants growing with other crops affects their yield. The researchers tested different timings for watering the plants and different combinations of crops. They found that giving water when the plants start to wilt gave the best results, with higher yields. When cotton was grown with blackgram, it produced the most cotton. But when cotton was grown with clusterbean, it had better overall results, like more income and efficiency. So, watering at the right time and choosing the right crop combination can help cotton plants grow better in dry soil.
