Abstract
In order to investigate the effects of spraying with various potassium sources, such as potassium silicate (KSil at 4.25 ml/l), potassium citrate (KCit at 1 g/l), potassium folvate (KF at 4.5 g/l), and potassium thiosulpahte (KTS at 1.25 ml/l), as well as the control (spraying with water) on the plant growth, N, P and K uptake by shoots, yield, and tuber quality of some potato cultivars, i.e., Spunta, Santana, Cara, Lady rosetta, and Hermes, two field experiments were conducted at a private farm in El-Salhyia El-Gadida District, Sharkia Governorate during 2021 and 2022 summer seasons. Fertilizing Santana cultivar with KCit as foliar spray gave the tallest plants and recorded maximum values of number of leaves/plant, and concentrations of total chlorophyll (a+b) in leaf tissues, P and K uptake by shoots, whereas fertilizing Cara cultivar with the same source increased number of aerial stems/ plant at 90 days after planting, yield/plant and total yield /fad in both seasons. Moreover, fertilizing Cara with KSil as foliar application gave the highest values of N, P and K contents in tuber at harvesting time. Spraying Hermes cultivar with KSil increased specific gravity in tubers Meanwhile, Fertilizing Lady rosetta cultivar with KCit as foliar application increased the concentration of Vit. C in tubers.
