e0“post-wheat harvest nitrate-N (NO3-N) at 90–105 cm soil depth in plots fertilised with 120 or 180 kg N/ha was greater for the rice–wheat system (6.5–8.1 mg/kg) than for the pigeon pea–wheat system (5.8–6.0 mg/kg)”

Other claims from this paper (8)
- Intervention effect Wheat yields following pigeon pea significantly exceeded yields following rice in 1999–2000 and 2000–01.
- Intervention effect Wheat yield after pigeon pea did not significantly differ from rice in 1998–99.
- Intervention effect Economic optimum wheat nitrogen dose was lower in the pigeon pea system than the rice system.
- Intervention effect Soil organic carbon increased at 0–15 cm after pigeon pea cultivation.
- Intervention effect Soil organic carbon increased at 15–30 cm after pigeon pea cultivation.
- Intervention effect Continuous rice–wheat cultivation increased soil bulk density over baseline.
- Intervention effect Adding pigeon pea maintained soil bulk density at the initial level.
- Recommendation The authors suggest periodic pigeon pea introduction to reduce wheat productivity decline from continuous rice–wheat cultivation.
