Sugar beet growth and yield as influenced by irrigation source as well as fertilization

A trial experiments laid out in Al- Amarna village , El-Manzala center, El- Dakahlia Governorate, Egypt during 2021/2022 and 2022/2023 seasons, to investigate sugar beet growth, yield and quality, variety (Melodia ) influenced by water source ) canal water 100%, mixed water (canal water50% + drainage water50%) and drainage water 100%) and fertilization treatments i.e Control (without any fertilization), 90 ,120 Kg N / feddan,24 , 48 Kg K2 O / feddan , 90 Kg N plus 24 Kg K2 O / feddan, 90 Kg N + 48 Kg K2 O / feddan ,120 Kg N plus 24 Kg K2 O / feddan and 120 Kg N + 48 Kg K2O/ feddan). Results illustrated that the interaction between sources of irrigation water and treatment of fertilization on all measured characters was significant in both seasons. At all water sources treated plants by 120 Kg N / feddan plus 48 Kg K2O/ feddan had the highest values of all traits measurements.This study recommended that applied 120 Kg N / feddan+ 48 Kg K2O/ feddan treatment alleviated the deleterious effect of drainage water and improvement sugar beet growth and productivity.
