Other claims from this paper (11)
- Intervention effect Growth, dry matter partitioning and yield components responded positively to N and S fertilization, with the magnitude of response varying with N and S level.
- Association Days to tasseling, silking and physiological maturity were delayed with increasing N and S levels.
- Association Plant height and mean single leaf area increased with increasing N and S levels.
- Intervention effect Dry matter partitioning in stem, leaf, ear and grains increased with increasing N and S levels and decreased in control plots.
- Intervention effect Thousand grains weight was heaviest when both N and S were applied at the highest rates.
- Intervention effect Grain yield was highest, at 3122 kg ha -1, where N was applied at 160 kg ha -1, compared with control plots.
- Intervention effect Grain yield increased to a maximum of 2882 kg ha -1 when S was applied at 40 kg ha -1, compared with control plots.
- Intervention effect Harvest index ranked first when both N and S were applied at the highest rates of 160 kg N and 40 kg S ha -1, at 27.8% (S 27.7%).
- Association Harvest index showed a positive relationship with the increase in grain yield and yield components in maize.
- Intervention effect All three N levels and two S levels increased yield components, grain yield and harvest index compared with the control.
- Recommendation Applying the highest S at 40 kg S ha -1 and N at 160 kg N ha -1 could increase maize productivity in the study area.
