- Intervention effect Irrigation up to 65 BBCH reduced 100-seed weight of castor by 11.9% compared with normal irrigation.
- Intervention effect Irrigation up to 65 BBCH reduced grain yield of castor by 34.9% compared with normal irrigation.
- Intervention effect Irrigation up to 65 BBCH reduced biological yield of castor by 24.2% compared with normal irrigation.
- Intervention effect Irrigation up to 65 BBCH reduced castor oil percent by 24.9% and oil yield by 51.7% compared with normal irrigation.
- Intervention effect Irrigation treatment, humic acid and zinc nano-chelate significantly affected the number of capsules, number of seeds and 100-seed weight of castor.
- Intervention effect Irrigation treatment, humic acid and zinc nano-chelate significantly affected the grain yield, oil percent and chlorophyll content of castor.
- Intervention effect Foliar application of zinc nano-chelate increased grain number of castor by 14.4%.
- Intervention effect Foliar application of zinc nano-chelate increased 100-seed weight of castor by 8.4%.
- Intervention effect Foliar application of zinc nano-chelate increased grain yield of castor by 18.4%.
- Observation The highest oil content of castor, 45.4%, was obtained under normal irrigation.
- Observation The highest oil yield of castor, 943.3 kg/ha, was obtained under normal irrigation.
- Intervention effect Non-application of humic acid decreased leaf chlorophyll content of castor.
- Intervention effect Irrigation up to 65 BBCH decreased leaf chlorophyll content of castor.
- Observation The highest superoxide dismutase activity in castor was observed without foliar zinc nano-chelate and with two-fold humic acid under irrigation up to 65 BBCH.
- Association Seed oil percent of castor was positively correlated with functional traits and total chlorophyll content.
- Association Seed oil percent of castor was negatively and significantly correlated with antioxidant enzyme activity.
- Observation Capsule number, 100-seed weight, grain yield and oil yield were the main factors affecting seed oil percent of castor in regression.
- Intervention effect Humic acid at recommended amounts together with zinc nano-chelate improved growth, physiological traits and tolerance to limited irrigation in castor.
