Optimizing Planting Density and Nitrogen Boosts Crop Yields Dramatically.
Planting more Ningjing 3 rice plants closer together and giving them the right amount of nitrogen can increase grain yield. The best results were seen with a planting density of 45×104 plants per hectare and 330 kg of nitrogen per hectare. The key factor for higher grain yield was having more spikelets in the population.
