摘要
在2016/2017年和2017/2018年连续两个冬季，在埃及Qalyobia省的私人农场进行了两项田间试验。本试验旨在研究土壤钾肥水平(0、50和100 kg K2O/fad.)和叶面喷施营养液(Aquacool)对粘土条件下甜菜根cv Balady生长、产量和根系品质的影响。结果表明，在100 K2O/fad的条件下，甜菜根与钾的交互作用显著。在硫酸钾调控和高水平(2 cm/L)营养物(水产液)喷施处理下，植株高度、单株叶数、叶片鲜重和干重、根系总产量及其组成(根重、根长和根径)以及根组织中N、P、K、总糖和维生素C含量最高。
Effect of Potassium Fertilization and Foliar application of Compound Fertilizer on Growth, Yield and Root Quality of Beetroot under Clay Soil conditions
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.
