Other claims from this paper (11)
- Intervention effect Maximum plant height (0.76 m) of 'Perfecta' onions was obtained with a sulphur dose of 57 kg S ha-1.
- Intervention effect The maximum number of leaves per plant (7.2) of 'Perfecta' onions was obtained with 41 kg S ha-1.
- Intervention effect The maximum dry weight of leaves (201.6 g) of 'Perfecta' onions was obtained with 47 kg S ha-1.
- Intervention effect The maximum productivity (79 t ha-1) of 'Perfecta' onions was obtained with 45 kg S ha-1.
- Intervention effect Onion productivity was 16% lower when sulphur was not applied.
- Observation About 47% of total onion bulb production was ranked in classes 3 and 4, which have higher commercial value.
- Intervention effect Maximum onion pungency (1.5 umol g-1) was obtained with 65 kg S ha-1, about 55% higher than when sulphur was not applied.
- Observation Pyruvic acid levels in onion were low in all sulphur treatments.
- Association The interaction between sulphur dose and period of evaluation influenced soil pH and soil sulphur content.
- Intervention effect Increased sulphur supply increased the levels of foliar N and S-SO4 2- in onion.
- Intervention effect Increased sulphur supply decreased foliar Ca 2+ and Mg 2+ in onion.
