Other claims from this paper (10)
- Intervention effect Liming significantly increased fresh and dry biomass, grain and juice sugar yield.
- Intervention effect Lime reduced exchangeable soil Mn and Al.
- Intervention effect Lime increased biomass Mg concentration.
- Intervention effect Lime decreased biomass Mn concentration.
- Association Biomass and juice sugar yield were not consistently related to N, P or K applications.
- Intervention effect On nonlimed soil, high N with low P-K decreased sugar yields yield.
- Observation Maximum dry biomass yield on limed soil occurred at the stated N-P-K rates.
- Observation Maximum sugar yield on limed soil occurred at the stated N-P-K rates.
- Observation Some lower-fertilizer treatments did not yield significantly differently from maxima.
- Recommendation The authors recommend correcting acidity and magnesium deficiency for maximal fertilizer response.
