Other claims from this paper (19)
- Intervention effect Seaweed as foliar spray plus 50% of recommended NPK significantly increased fresh weight, dry weight and leaf area of potato relative to control (100% NPK).
- Intervention effect Seaweed as foliar spray plus 50% of recommended NPK significantly increased total tuber yield, number of tubers per plot and average tuber weight of potato relative to control (100% NPK).
- Intervention effect Foliar humic acid or seaweed extract plus 50% NPK significantly increased tuber dry matter, specific gravity and starch content of potato relative to control (100% NPK).
- Intervention effect Foliar humic acid or seaweed extract plus 50% NPK significantly reduced reducing sugars in potato tubers relative to control (100% NPK).
- Intervention effect Humic acid plus 50% NPK significantly increased NPK-content of potato plants in both seasons relative to control (100% NPK).
- Intervention effect Humic acid plus 50% NPK significantly increased SOD activity of potato plants in the first season relative to control (100% NPK).
- Intervention effect Organic stimulators plus 50% NPK significantly decreased nitrate and nitrite content in potato tubers compared with full or half dose NPK.
- Association Potato cultivars differed significantly in all studied characters.
- Association Cultivar Spunta had more fresh and dry weight per plant and leaf area than the other cultivars in both seasons.
- Association Cultivar Spunta had more tuber yield and yield components than the other cultivars in both seasons.
- Association Cultivar Spunta had more nitrate content and SOD activity than the other cultivars.
- Association Cultivars Fridor and Oceania had significantly higher dry matter and specific gravity than the other two cultivars.
- Association Cultivars Fridor and Oceania had significantly higher NK-uptake and starch content than the other two cultivars.
- Association Cultivars showed insignificant differences in P-uptake and nitrite content.
- Association Cultivar Alaska gave the highest reducing sugars compared with the other cultivars.
- Recommendation Foliar seaweed extract or humic acid with half-dose NPK is recommended for high productivity and quality of potato; increased SOD activity from the stimulants is interpreted as protecting plants against cold stress.
- Observation Cultivar Spunta with seaweed and 50% NPK was among the most effective treatments.
- Observation Cultivar Fridor with humic acid and 50% NPK was among the most effective treatments.
- Association The interaction between potato cultivars and organic stimulators plus inorganic fertilizers had significant effects on all characters.
