The researchers studied how to grow Nanjing 44 rice to produce very high yields. They found that having more effective panicles and grains per panicle can increase the yield. The best way to increase yield is by increasing the number of effective panicles. They also discovered that Nanjing 44 can achieve high yields by using specific planting techniques and nitrogen levels. Dry-raising seedlings and thin-planting with the right amount of nitrogen can help achieve super-high yields. Additionally, using plastic plates and wheat straw for planting can also lead to high yields when the nitrogen levels and planting density are balanced.
