Other claims from this paper (8)
- Observation The six high-oleic sunflower hybrids evaluated were similar in phenological development and yield.
- Observation Two sunflower varieties had less than 50% emergence.
- Observation Poor hybrid seed quality was a constraint to sunflower planting under rainfed conditions.
- Intervention effect Basal application of 20:20:15 (N:P2O5:K2O) at 200 kg ha−1 produced sunflower achene yield of 2423 kg−1.
- Intervention effect S-metolachlor applied post-sowing pre-emergence was the most effective weed control and significantly increased sunflower achene yield.
- Intervention effect Post-emergence weed control did not prevent sunflower yield loss from weed competition.
- Recommendation Sunflower can be grown successfully as a dry-season crop in North-West Cambodia when planted no-tillage on residual soil water after maize.
- Recommendation Critical requirements for dry-season sunflower success are minimal soil disturbance, adequate fertiliser at sowing, and pre-emergence weed control.
