Other claims from this paper (9)
- Intervention effect Stand densities of at least 9 in single 75 cm or twin rows gave the highest silage yields, with significant differences in only two of five site years.
- Intervention effect Increasing N-P-K beyond 200–30–167 kg ha”; slightly increased crude protein in 1980.
- Intervention effect Increasing N-P-K beyond 200–30–167 kg ha”; significantly increased crude protein in 1981 and 1982.
- Intervention effect Higher fertilization increased Mn and Zn concentrations in corn silage.
- Mechanism The authors attributed increased Mn and Zn in silage to nitrification lowering surface soil pH and increasing availability.
- Intervention effect Fertilizer program did not significantly influence dry matter yield, fiber, energy or other mineral nutrients.
- Observation The identified management practices gave corn silage yields equal to those in the cooler Georgia mountain region.
- Observation The management practices exceeded average South Carolina corn silage production by approximately 40%.
- Observation Those yields were achieved without reducing apparent feed quality.
