Other claims from this paper (15)
- Intervention effect Drought stress, humic acid and Zn-nano fertilizer significantly affected the number of capsules, number of seeds and 100-seed weight of castor bean.
- Intervention effect Drought stress, humic acid and Zn-nano fertilizer significantly affected seed yield and oil yield of castor bean.
- Intervention effect Drought stress, humic acid and Zn-nano fertilizer significantly affected protein percentage and protein yield of castor bean.
- Intervention effect Drought stress, humic acid and Zn-nano fertilizer significantly affected the activities of catalase, superoxide dismutase and peroxidase in castor bean.
- Intervention effect Severe drought stress reduced the number of capsules of castor bean by 33.9% relative to normal irrigation.
- Intervention effect Severe drought stress reduced the number of seeds of castor bean by 32.7% relative to normal irrigation.
- Intervention effect Severe drought stress reduced 100-grain weight of castor bean by 16.0% relative to normal irrigation.
- Intervention effect Severe drought stress reduced seed yield of castor bean by 43.0% relative to normal irrigation.
- Intervention effect Severe drought stress reduced oil yield of castor bean by 59.3% relative to normal irrigation.
- Intervention effect Severe drought stress reduced protein yield of castor bean by 29.9% relative to normal irrigation.
- Intervention effect The highest yield components of castor bean were achieved with foliar application of humic acid (recommended rate) and Zn-nano fertilizer under normal irrigation in the second year.
- Intervention effect The highest oil content, protein content and photosynthetic pigments of castor bean were achieved with foliar application of humic acid (recommended rate) and Zn-nano fertilizer under normal irrigation in the second year.
- Intervention effect Foliar application of Zn-nano fertilizer decreased the activities of catalase, superoxide dismutase and peroxidase in castor bean.
- Association According to partial regression analysis, the recommended rate of humic acid changed the nature of the relationships governing the measured characteristics of castor bean, especially under drought stress.
- Recommendation The authors conclude that foliar application of humic acid (recommended rate) and Zn-nano fertilizer could create excellent drought resistance in castor under dry and semi-arid conditions by improving yield, yield components and physiological traits.
