e0“The effect of poultry manure application on maize (Zea mays) growth and yields was studied on a Ferric Acrisol in the semi-deciduous rain forest zone of Ghana”
e2“The 4 t pm/ha rate produced maize grain yield of 2.07 t/ha which was statistically not different from that of the chemical fertilizer rate (2.29 t/ha)”
e3“which was statistically not different from that of the chemical fertilizer rate (2.29 t/ha) and 6 t pm/ha (2.60 t/ha)”

Other claims from this paper (9)
- Intervention effect The 4 t pm/ha rate gave maize grain yield of 2.07 t/ha, not statistically different from the chemical fertilizer rate (2.29 t/ha).
- Intervention effect Maize grain yield at 6 t pm/ha was not statistically different from 8 t pm/ha.
- Intervention effect Split application of 4 t pm/ha (2 x 2 t pm/ha) gave maize biomass and grain yields similar to 4 t pm/ha.
- Intervention effect 2 t pm/ha + 30-20-20 kg NPK/ha gave maize biomass and grain yields similar to 4 t pm/ha.
- Intervention effect Poultry manure treatments produced higher height, leaf area index and biomass in maize.
- Intervention effect Poultry manure application increased soil N levels by over 53%, from 0.09% to 0.14%.
- Intervention effect Exchangeable cations increased with poultry manure application.
- Recommendation The authors recommend 4 t pm/ha of poultry manure as the application rate for maize on this soil type and agro-ecology.
- Recommendation Poultry manure can serve as a suitable alternative to chemical fertilizer in the forest zone of Ghana.
