High nitrogen application rate and planting density reduce wheat grain yield by reducing filling rate of inferior grain in middle spikelets
Excessive use of nitrogen fertilizer and high planting density reduce grain weight in wheat. However, the effects of high nitrogen and planting density on the filling of grain located in different positions of the wheat spikelet are unknown. A two-year field experiment was conducted to investigate t...
