Effect of different N rates on yield and benefit of edible sunflower in Inner Mongolia
IPNI-2017-CHN-NM01
Inner Mongolia Autonomous Region (IMAR) is the main sunflower-growing region, with area and production accounting for over 50% of the total in China. In IMAR, 80% of the sunflower is produced for edible nuts. The amount of nitrogen (N) required for producing 100 kg achenes is 3. 8 to 4. 9 kg N/ha. Farmers frequently over apply N fertilizers, resulting in low N use efficiency and low benefit. Read more
