Other claims from this paper (13)
- Intervention effect Drilled fertilizer significantly increased grain and straw yields in 13 experiments.
- Observation Two experiments found no significant difference between placements.
- Intervention effect Broadcast fertilizer significantly increased grain yield in one experiment.
- Intervention effect Drilled fertilizer was twice as effective as broadcast fertilizer.
- Intervention effect Broadcast fertilizer increased straw yield by 6·3 cwt. per acre.
- Intervention effect Drilled fertilizer increased grain yield by 8·0 cwt. per acre.
- Intervention effect Drilled fertilizer increased straw yield by 14·6 cwt. per acre.
- Intervention effect Drilling fertilizer tended to delay brairding.
- Intervention effect Fertilizer-drilled crops caught up with and overtook broadcast crops.
- Intervention effect Drilling fertilizer increased tillering.
- Intervention effect Drilling fertilizer decreased weed growth.
- Recommendation More than about 3 cwt. soluble fertilizer per acre in drills risks poor plant stands.
- Association Higher fertilizer analysis reduced the delay in brairding at equal nutrient amounts.
