The researchers studied the effects of phosphorus fertilizer on two types of mungbean plants in a salty area. They tested different levels of phosphorus on the plants and found that one type of mungbean produced the most pods per plant, while the other had the heaviest seeds. The plants treated with a medium level of phosphorus had the best overall growth and yield. The combination of phosphorus levels and mungbean varieties had a big impact on the plants' growth and yield. Overall, the study showed that the right amount of phosphorus can significantly improve mungbean production in salty areas.
