Other claims from this paper (14)
- Intervention effect Cabbage head weight was generally greater with mineral fertiliser than with organic fertiliser.
- Intervention effect Potassium nitrate at 400 kg N/ha gave cabbage yields 66% higher than no added fertiliser.
- Intervention effect Ammonium nitrate at 400 kg N/ha gave cabbage yields 61% higher than no added fertiliser.
- Intervention effect Ammonium sulphate at 400 kg N/ha gave cabbage yields 40% higher than no added fertiliser.
- Intervention effect Urea at 400 kg N/ha gave cabbage yields 49% higher than no added fertiliser.
- Intervention effect Farmland manure at 400 kg N/ha gave cabbage yields 44% higher than no added fertiliser.
- Intervention effect Ammonium nitrate at 342 kg N/ha gave higher cabbage plant yields than other fertiliser applications in the regression analysis.
- Association Organic anion accumulation in cabbage plants increased with increasing NO3 nutrition.
- Association Cation concentration in cabbage increased in parallel with organic anion accumulation.
- Observation Total inorganic anion levels in cabbage were relatively constant.
- Intervention effect Increasing NO3 nutrition stimulated organic anion accumulation (glutamate, malate, oxalate) far more than ammonium.
- Intervention effect The increases observed in cabbage were highest with potassium nitrate and lowest with no added fertiliser.
- Intervention effect Farmyard manure gave cabbage with lower total N, nitrate and oxalic acid contents than mineral fertilisers.
- Recommendation Ammonium sulphate at 250 kg N/ha is the most suitable rate for cabbage quality, given its lower yield risk for human nutrition.
