Other claims from this paper (11)
- Intervention effect Application of N, S and B fertilizers significantly increased yield attributes, yield and oil quality parameters of spring sunflower.
- Intervention effect Calcium ammonium nitrate was superior to urea in nutrient concentration and uptake by sunflower.
- Intervention effect 25 kg S/ha was more effective than 50 kg S/ha in increasing growth, yield attributes and yields of sunflower.
- Intervention effect 50 kg S/ha gave the highest seed yield (1.99 t/ha), 13% higher than the control.
- Intervention effect 1.5 kg B/ha gave the highest seed yield (2.01 t/ha), 13.5% and 6.3% more than the control and 0.75 kg B/ha.
- Intervention effect Boron application increased total nutrient concentration and uptake by sunflower.
- Intervention effect S and B application improved the content of unsaturated fatty acids (linoleic and oleic) in sunflower oil.
- Intervention effect S and B application reduced the content of saturated fatty acids (palmitic and stearic) in sunflower oil.
- Intervention effect S and B application reduced saponification of sunflower oil.
- Intervention effect S and B application increased the iodine value of sunflower oil significantly.
- Intervention effect N sources and S and B levels did not markedly change the acid value of sunflower oil.
