Abstract
Two field experiments were carried out at private farm in Qalyobia Governorate, Egypt during the two successive winter seasons of 2016/2017 and 2017/2018. The study aimed to investigate the effect of potassium soil fertilizer levels (0, 50 and 100 kg K2O/fad.) and foliar spray with nutrient compound (Aquacool) on growth, yield and root quality of beetroot plants cv Balady grown in clay soil conditions. The gained results indicated that, the interaction between fertilizing beetroot with potassium at 100 K2O/fad. in the regulate potassium sulfate and spraying with high levels (2 cm/L) of nutrient compound (Aquacool) gave the highest values of plant height, number of leaves/ plant, leaves fresh and dry weight, total roots yield and its components (root weight, length and diameter) as well as highest contents of the percentage of N, P, K, total sugar and vitamin C in root tissue.
