Andrew David Hunt NCSU Libraries Repository (North Carolina State University Libraries) 2009
Other claims from this paper (18)
- Intervention effect Nitrogen rate affected cotton yield in Virginia in both years and North Carolina in 2006.
- Intervention effect Nitrogen did not affect cotton yield in 2005.
- Association The 2006 North Carolina cotton yield response to N was quadratic.
- Association Virginia cotton yield responded linearly to nitrogen rate.
- Intervention effect Increasing nitrogen above 112 kg N ha‐ 1 was not significant.
- Intervention effect Plant growth regulator use did not alter the optimum N rate.
- Intervention effect Starter fertilizer did not affect cotton yield in either year.
- Intervention effect Starter fertilizers affected early vigor and plant height in 2006, with 11‐ 37‐ 0 giving greater values.
- Intervention effect The 11‐ 37‐ 0 fertilizers gave the highest dry weight in 2006 and 2007.
- Intervention effect Tillage influenced early cotton vigor, stand counts, and height.
- Intervention effect No-till systems may produce more bolls in 2007.
- Association The extra bolls did not translate into increased lint yield.
- Intervention effect Starter fertilizer provided little agronomic advantage and no yield change versus untreated control.
- Association No tillage system showed conclusive greater starter-fertilizer response.
- Recommendation Broadcasting nitrogen was sufficient under reduced tillage in 2006.
- Intervention effect Injecting nitrogen did not improve final yield under reduced tillage in 2006.
- Intervention effect Fertilizer nitrogen placement at first square had no significant effect on final yield in 2007.
- Association N application methods would likely perform similarly in both tillage systems.
