Abstract

Forest is one of the critical factors limiting the productivity of potatoes (Solanum tuberosum L.) during winter season in Egypt. This field experiment was conducted at El Kanater Horticultural Research Station in Kaluobia Governorate, Egypt, during the two winter seasons of 2021/2022and 2022/2023 to investigated the effect of mineral and bi-phosphorus fertilizers treatments and foliar spraying with salicylic acid, potassium citrate and potassium silicate and their interaction on tubers yield and tubers quality of potato (Spunta cv.).: The experiment was laid out as (RCBD) in 4×4 factorial arrangement of phosphorus (phosphoric acid (40 l/fed) + phosphorene, phosphoric acid (60 l/fed) + phosphorene, phosphoric acid (80 l/fed) + phosphorene, and Control 400kg calcium superphosphate) and foliar spraying (tap water as control), potassium silicate at 2 g/l, potassium citrate at 3 g/l, and Salicylic acid 0.5 g/l.).   Analysis of the data revealed that the interaction effect of phosphorus (phosphoric acid 80 l/fed+ phosphorene) and foliar spraying with potassium citrate 3g/l significantly improved the tubers yield/ plant, tubers yield/ fed, number of tubers, potato tuber physical properties (tuber length, tuber diameter, tuber weight) and potato tuber chemical properties (total carbohydrate, Starch, Total protein ana Dry matter).
