| Abstract | ||||
| 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 investigate the effect of mineral and bio-phosphorus fertilizers treatments and foliar spraying with salicylic acid, potassium citrate and potassium silicate and their interaction on the vegetative growth and chemical constituents of plant foliage of potato plants cv.Spunta. phosphorus fertilization are phosphoric acid (40 l/fed) + phosphorene as biofertilizer, phosphoric acid 60 l/fed + phosphorene, phosphoric acid 80 l/fed + phosphorene, and Control 400kg calcium superphosphate and foliar spraying treatments with potassium silicate at 2 g/l, potassium citrate at 3 g/l, and Salicylic acid 0.5 g/l in addition to control. Obtained results showed that the interaction effect of phosphorus (phosphoric acid 80 l/fed+ phosphorene and foliar spraying potassium citrate 3g/l significantly improved the vegetative growth parameters (plant height, number of main shoots, fresh and dry weight, total carbohydrate and NPK contents on leaves. | ||||
