Other claims from this paper (16)

Intervention effect Appropriate zinc fertilizer increased leaf soluble sugar.
Intervention effect Appropriate zinc fertilizer increased grain starch content.
Intervention effect Appropriate zinc fertilizer increased grain yield.
Observation The zinc amount maximizing leaf soluble sugar varied among Xunxian, Yuzhou and Yanshi.
Intervention effect Overall, 30 kg / ha zinc fertilizer maximized corn leaf soluble sugar at the three locations.
Intervention effect At equal zinc amount, soil application improved maize leaf soluble sugar more than soil plus spray application.
Intervention effect Zn15 maximized grain starch in Xunxian.
Intervention effect Zn30 maximized grain starch in Yuzhou.
Intervention effect Zn30 maximized grain starch in Yanshi.
Intervention effect At equal zinc amount, soil application improved grain starch more than soil plus spray application.
Intervention effect Soil zinc at 15 kg / ha plus two sprays of 7. 5 kg / ha maximized dry matter yield in Xunxian.
Intervention effect Soil zinc fertilizer 15 kg / ha maximized dry matter yield in Yanshi.
Intervention effect Soil plus spray zinc increased Xunxian summer corn dry matter.
Association Ground dry matter response varied with zinc amount in Yuzhou and Xunxian.
Association At each location, the zinc amount for maximum grain yield matched the amount for maximum dry matter yield.
Intervention effect At equal zinc amount, soil plus spray zinc gave better grain yield response in Yanshi and Yuzhou than Xunxian.
