Other claims from this paper (18)
- Observation Without phosphorus treatment, average rapeseed yield was only 190 kg hm-2.
- Intervention effect Phosphorus application significantly increased pods per plant, seed number and 1000-seed weight of rapeseed.
- Intervention effect Phosphorus application increased rapeseed yield 8.5 to 12.5 times compared with no phosphorus.
- Association Maximum rapeseed yields were obtained at phosphorus applications of 51.8-65.0 kg P2O5 hm-2.
- Intervention effect Phosphorus fertilizer rate significantly affected rapeseed phosphorus content, water content and oil content.
- Intervention effect Phosphorus fertilizer rate significantly affected rapeseed protein, glucosinolate and oleic acid.
- Intervention effect Phosphorus fertilizer rate significantly affected rapeseed linolenic acid and stearic acid.
- Intervention effect Erucic acid, linoleic acid and palmitic acid showed less response to phosphorus fertilizer rate in rapeseed.
- Intervention effect Rapeseed protein content tended to increase slowly with phosphorus fertilizer rate.
- Intervention effect Rapeseed glucosinolate content decreased significantly with phosphorus fertilizer rate.
- Intervention effect Excessive phosphorus fertilizer decreased rapeseed oleic acid content.
- Intervention effect Excessive phosphorus fertilizer increased rapeseed linolenic acid content.
- Association Seed phosphorus content, oil content and linolenic acid content had a greater direct positive effect on rapeseed yield.
- Association Water content, protein and linolenic acid had a greater indirect positive effect on rapeseed yield through seed phosphorus content.
- Association Glucosinolate and oleic acid had a greater indirect negative effect on rapeseed yield through seed phosphorus content.
- Association Linoleic acid and stearic acid had a greater indirect negative effect on rapeseed yield through seed phosphorus content.
- Recommendation A phosphorus fertilizer rate of 45-90 kg P2O5 hm-2 is recommended for rapeseed yield and edible oil quality.
- Recommendation A phosphorus fertilizer rate of 90-135 kg P2O5 hm-2 is recommended for forage cake meal protein yield.
