The study looked at how different soybean varieties respond to high levels of phosphorus, potassium, and calcium in soil. They found that some soybean lines grew better with more phosphorus, but too much phosphorus can be harmful. The best yield was seen with 450-500 kg of phosphorus per hectare. Different soybean lines showed varying growth patterns, with some doing better at early stages and others at later stages. It's important to find soybean varieties that grow well and are not harmed by too much phosphorus in the soil.
