Other claims from this paper (9)
- Observation 1980 drought and heat eliminated nitrogen and nitrapyrin responses.
- Intervention effect Grain yield, leaf N and grain protein responded typically to applied N.
- Association Grain protein depended on nitrogen rate.
- Association Grain protein was not consistently related to leaf nitrogen.
- Intervention effect Nitrapyrin did not influence grain protein.
- Intervention effect Fall nitrapyrin reduced fertilizer nitrogen needed for maximum yield by 15% to 18%.
- Intervention effect Spring nitrapyrin reduced fertilizer nitrogen needed by 3.2 to 4.7%.
- Observation Maximum-yield nitrogen requirement was equal for fall and spring applications with nitrapyrin.
- Recommendation Fall anhydrous ammonia with nitrapyrin was interpreted to increase plant nitrogen use efficiency.
