End-season drought lowered biological yield, seed yield and harvest index.
- Taxon
- safflower
Carthamus tinctoriuse0t0e1
Verbatim
e0“The end-season drought caused a decrease in the chlorophyll index, leaf area index, relative water content, plant height, yield components, biological yield, seed yield, harvest index, seed oil content, oil harvest index, and seed element content compared to regular irrigation”
t0“Application Methods of Zinc Sulphate Increased Safflower Seed Yield and Quality under End-Season Drought Stress”
e1“The effect of different methods of zinc application on the growth, yield, and quality of safflower seeds under regular irrigation and interruption of irrigation from flowering to harvest (82 and 80 DAS in the first and second years, respectively) was evaluated.”

- Intervention effect End-season drought lowered chlorophyll index, leaf area index and relative water content.
- Intervention effect End-season drought lowered plant height and yield components.
- Intervention effect End-season drought lowered seed oil content, oil harvest index and seed element content.
- Association The yield decrease coincided with lower capitol number and diameter, seed number per capitol and 1000-seed weight.
- Observation Drought damage was more severe in the second year than the first.
- Intervention effect Zinc sulfate increased studied traits in both years and irrigation conditions.
- Intervention effect Zinc sulfate improved yield and seed nitrogen, phosphorus and potassium contents.
- Intervention effect Zinc sulfate improved seed zinc and iron content.
- Association Increasing zinc sulfate concentration lowered seed phosphorus content with both application methods.
- Intervention effect Seed phosphorus content remained above the no-zinc treatment.
- Intervention effect Zinc increased biological, seed and oil yield.
- Observation Seed and oil yield responded more strongly to zinc than biological yield.
- Intervention effect Zinc increased seed and oil harvest index.
- Intervention effect Higher zinc sulfate concentrations improved performance under regular irrigation.
- Observation Medium and lower zinc sulfate concentrations worked better under stress.
- Intervention effect Flowering-stage spray at 5 g L−1 under normal irrigation gave the highest 1000-seed weight.
- Intervention effect Flowering-stage spray at 5 g L−1 under normal irrigation gave the highest potassium and zinc content.
- Intervention effect Foliar zinc sulfate spray improved seed yield more than soil application.
- Observation Soil zinc sulfate application affected biological yield more than seed yield.
