Other claims from this paper (19)
- Observation Annual rice yields across treatments ranged from 6214 to 11562 kg ha-1.
- Intervention effect NPKM raised yield 22.58% above NPK.
- Intervention effect NPM raised yield 15.35% above NPK.
- Intervention effect NKM raised yield 10.53% above NPK.
- Intervention effect PKM raised yield 4.41% above NPK.
- Intervention effect Organic plus inorganic N and P raised soil total and available phosphorus over NPK.
- Observation NPKM had the highest annual rice yield at 11562 kg ha-1.
- Observation NPKM had the highest soil organic carbon at 20.88 g kg-1.
- Observation NPKM had the highest soil total nitrogen at 2.30 g kg-1.
- Observation NPKM had the highest soil total phosphorus at 0.95 g kg-1.
- Observation NPKM had the highest soil total potassium at 22.50 g kg-1.
- Observation NPKM had the highest soil available phosphorus at 38.94 mg kg-1.
- Observation NKM had the highest soil available nitrogen at 152.40 mg kg-1.
- Observation NKM had the highest soil available potassium at 151.00 mg kg-1.
- Intervention effect N and P application produced soil nutrient surplus, which NPKM reduced.
- Observation Soils under every treatment were deficient in potassium.
- Association Soil organic carbon and total nitrogen correlated significantly with rice yield.
- Association Available nitrogen and total and available phosphorus correlated significantly with rice yield.
- Recommendation The authors concluded balanced N, P and K with manure was required.
