Response of different sugar beet cultivars to nitrogen fertilizer rates under the arid land conditions

الملخص EN

This study was conducted during 2016-2018 at the Agriculture Research Station of King Abdulaziz University at Hada Al-Sham, Saudi Arabia.

The study aimed to evaluate three sugar beet cultivars (Farida, Dita and Heros) under three nitrogen fertilizer rates (100, 200 and 300 kg N/ha).

As nitrogen fertilizer rate increased root yield, yield components, sucrose (%) and yield significantly increased in both seasons.

Fresh root yield under 300 kg N/ha was the highest in both seasons.

Farida cv.

was the highest in root yield (60.62 t/ha and 97.00 t/ha) and sucrose yield (4.15 and 6.95 t/ha) in both seasons, respectively.
