t0“Sweet Corn Growth Responses”
e5“The best fertilizer responses were obtained with 56 kg/ha each of N and P banded for ‘Northern Belle’, with 112 kg/ha of N (75% broadcast, 25% banded), and 56 kg/ha P banded for ‘Deep Gold’. These treatments increased yields (by 36% and 60%, respectively, compared to the check)”

Other claims from this paper (19)
- Intervention effect Calcitic, calcitic with 3% Mg and dolomitic limes at 4.5 MT/ha increased sweet corn vigor, yield and percentage of marketable ears.
- Intervention effect The same lime treatments increased leaf N and leaf P in sweet corn.
- Intervention effect The same lime treatments decreased leaf Mn and Zn in sweet corn.
- Intervention effect Calcitic lime increased leaf Ca by 21%.
- Intervention effect Calcitic lime increased leaf Mg by 31%.
- Intervention effect Dolomitic lime more than doubled leaf Mg in sweet corn.
- Intervention effect Dolomitic lime did not affect leaf Ca in sweet corn.
- Intervention effect Dolomitic lime increased leaf Mg by 55% 60 days after application.
- Intervention effect Northern Belle yields increased by 36% under 56 kg/ha each of N and P banded, compared with the check.
- Intervention effect The fertilizer treatments increased plant height, ear size and ear weight in sweet corn.
- Intervention effect The fertilizer treatments hastened sweet corn maturity by 5 days.
- Intervention effect Additions of K or Mg did not improve the fertilizer response.
- Intervention effect Using Ca(NO3)2 rather than NH4NO3 as N source reduced sweet corn height and yield.
- Intervention effect Using Ca(NO3)2 rather than NH4NO3 as N source delayed sweet corn maturity.
- Intervention effect Leaf Ca, Mg and Mn were lower with Ca(NO3)2 than with NH4NO3 and urea.
- Intervention effect Urea increased leaf N, P and Mn in sweet corn.
- Intervention effect Urea increased leaf Cu and Zn in sweet corn.
- Intervention effect NH4NO3, Ca(NO3)2 and urea enhanced leaf Ca and Mg in sweet corn.
- Intervention effect KCl depressed leaf Ca and Mg in sweet corn.
