Mostafa Mohamed Zahran Alexandria Journal of Soil and Water Sciences/Alexandria Journal of Soil and Water Sciences 2024. doi:10.21608/ajsws.2024.303372.1017

Other claims from this paper (11)

Intervention effect Biostimulants decreased the negative impact of water shortage on onion.
Intervention effect YE gave the highest onion bulb yield and water-use efficiency, followed by YE+KH.
Intervention effect YE gave the highest onion dry matter and NPK content and uptake, followed by YE+KH.
Intervention effect YE gave the highest onion protein yield, followed by YE+KH.
Intervention effect YE produced the highest soil water holding capacity, followed by YE+KH.
Intervention effect KH gave the highest available soil NPK, EC and soluble ions, followed by YE+KH or YE.
Intervention effect Soil pH was lowest under KH or KH+YE.
Intervention effect At 80% ETc, YE reduced dry onion yield by only 3.18% relative to YE at 100% ETc.
Intervention effect YE at 80% ETc saved 20% irrigation water against YE at 100% ETc.
Intervention effect YE at 80% ETc increased onion dry production by 24.36% relative to untreated plants at 100% ETc.
