Other claims from this paper (11)
- Intervention effect Application of P significantly increased plant height, number of branches and leaf dry weight of grain amaranth relative to 0 kgP/ha.
- Intervention effect Application of P significantly increased grain yield per plant of grain amaranth relative to 0 kgP/ha.
- Association Grain yield of the three grain amaranth varieties increased significantly in the order NH/493 > NH/445 > NH/452.
- Observation The optimum P rate across varieties for leaf dry-matter yield was 51.8 kgP/ha.
- Observation The optimum P rate for grain yield production was 48.4 kgP/ha.
- Intervention effect SSP increased grain yield of grain amaranth compared with the control; SSP grain yield was 21.3 g/plant.
- Intervention effect SRP increased grain yield of grain amaranth compared with the control; SRP grain yield was 16.9 g/plant.
- Intervention effect ORP increased grain yield of grain amaranth compared with the control; ORP grain yield was 16.0 g/plant.
- Observation Grain yield of grain amaranth in the control without P source was 7.8 g/plant.
- Association Growth of grain amaranth was ranked SSP > ORP > SRP > control.
- Recommendation Amaranth productivity indices could alternatively be improved with indigenous P sources.
