Other claims from this paper (8)
- Intervention effect In the hot dry season, disease began 23 days earlier under no-till than conventional tillage.
- Intervention effect No-till had higher gray leaf spot disease than conventional tillage in the hot dry season.
- Intervention effect Stubble tillage conserved soil moisture.
- Intervention effect Stubble tillage gave higher grain yields than conventional tillage.
- Intervention effect Conventional tillage yielded 28 kg ha −1 less than treatment leaving 82% stubble.
- Intervention effect Fungicide increased grain yield by 477 kg ha− in unfavorable seasons.
- Intervention effect Fungicide increased grain yield by 3830 kg ha− in seasons favorable for gray leaf spot.
- Recommendation Judicious fungicide application is recommended to reduce financial loss while retaining stubble tillage.
