- Intervention effect Half-rate fertilizer plus azolla green manure gave rice system yield of 9.07 t/ha/year.
- Intervention effect Half-rate fertilizer plus farmyard manure gave rice system yield of 8.75 t/ha/year.
- Intervention effect Removing all recommended fertilizer without organic manure reduced rice system yield about 52% versus RDF.
- Intervention effect Reducing recommended fertilizer by 50% without organic manure reduced rice system yield about 23% versus RDF.
- Intervention effect Reducing recommended fertilizer by 25% without organic manure reduced rice system yield about 10% versus RDF.
- Intervention effect Replacing fertilizer nitrogen with organic sources caused about 10% lower yield during the first five years.
- Observation The yield advantage from green manuring appeared after 10 years.
- Observation The yield advantage from farmyard manure appeared after 15 years.
- Observation Supplementing 25% nitrogen with paddy straw gave no yield advantage after 31 years.
- Observation The azolla integrated treatment had the highest system gross returns of 1,11,870.
- Observation The azolla integrated treatment had net returns of 65,644.
- Observation The azolla integrated treatment had the highest benefit:cost ratio of 2.42.
