- Intervention effect Recommended NPK with ZnSO4 to rice and CaSO4 to groundnut gave the highest system REY (10.78 t/ha), above recommended NPK alone (10.36 t/ha).
- Intervention effect The system REY of the two best treatments increased by 73 and 66% over the control (6.23 t/ha).
- Intervention effect The system REY of the two best treatments increased by 25 and 20% over the farmers practice (8.63 t/ha).
- Observation Agronomic efficiency of N was 19.8 kg REY/kg applied nutrient in the rice-groundnut system.
- Observation Agronomic efficiency of P was 29.0 kg REY/kg applied nutrient in the rice-groundnut system.
- Observation Agronomic efficiency of K was 17.2 kg REY/kg applied nutrient in the rice-groundnut system.
- Intervention effect Adding recommended P to recommended N increased the agronomic efficiency of N by 49% relative to N alone.
- Intervention effect Adding recommended K to recommended N increased the agronomic efficiency of N by 55% relative to N alone.
- Intervention effect Adding recommended P and K to recommended N increased the agronomic efficiency of N by 108% relative to N alone.
- Intervention effect Applying recommended P with recommended NK increased the agronomic efficiency of P and K by 40% relative to N alone.
- Intervention effect NPK with ZnSO4 to rice and CaSO4 to groundnut gave the highest system net returns (63,123/ha).
- Intervention effect Recommended NPK applied to both crops gave system net returns of 60,509/ha, second to the NPK with ZnSO4 and CaSO4 treatment.
- Intervention effect Balanced nutrient application led to higher nutrient uptake in the two best treatments, due to high biomass production.
