Other claims from this paper (18)
- Intervention effect N fertilization from different sources and combinations increased maize grain yield from 1911 kg/ha in the control to 2065–3763 kg/ha.
- Intervention effect The highest urea N rate gave the highest maize grain yield, 3763 kg/ha, double the control.
- Intervention effect N 90U+30PM and N 60U+60PM raised maize grain yield by 85 and 83%.
- Intervention effect PM alone gave lower maize grain yields (41 and 44% increase) than the respective urea N treatments.
- Intervention effect Integrated urea + PM was superior to other treatments in enhancing the uptake of N, P and K in maize.
- Intervention effect Averaged over two years, N 90U+30PM and N 60U+60PM gave N uptake of 88 and 85 kg/ha, higher than the control (52.5 kg/ha).
- Intervention effect Averaged over two years, N 90U+30PM and N 60U+60PM gave P uptake of 16.5 and 17.5 kg/ha, higher than the control (11.5 kg/ha).
- Intervention effect Averaged over two years, N 90U+30PM and N 60U+60PM gave K uptake of 48.5 and 53.5 kg/ha, higher than the control (33.5 kg/ha).
- Observation Nitrogen use efficiency was 29% in PM treatments.
- Observation Nitrogen use efficiency was 30–39% in combined treatments.
- Observation Nitrogen use efficiency was 40% for urea N treatments.
- Intervention effect Application of PM enhanced soil pH from 7.39 to 7.65 and 7.78.
- Intervention effect Application of PM increased soil organic matter by 22 and 32%.
- Intervention effect Application of PM increased soil total N by 21 and 26%.
- Intervention effect Application of PM increased soil available P by 44 and 55%.
- Intervention effect Application of PM increased soil available K by 10 and 15%.
- Intervention effect Using 50% recommended mineral N with PM saves almost 50% of mineral N fertilizer compared with a system with only mineral N.
- Recommendation Combined treatment would help minimize the use of high-cost synthetic mineral fertilizers in a sound management strategy.
