Impact on growth, yield and nutritional status of tomato plants grown in saline soil by vermicompost and ascorbic acid

The experiment was designed to investigate the effect of vermicompost rates (0, 6, 8 and 10 ton fed-1) and ascorbic acid levels (0, 100 and 200 ppm) on growth, yield and nutritional status of tomato plants (Lycopersicum esculentum L. cv Kasel rock) grown in saline soil of Tamia District, El-Fayoum Governorate at two seasons 2018 and 2019. The results indicated that the addition of vermicompost supplemented by spraying with concentrations of ascorbic acid has a significant and clear effect on the growth characteristics and quality and quantity of the tomato plants grown in saline soil at two seasons 2018 and 2019. The highest values of the various components of the tomato plants growth and yield were obtained by adding the high rate of vermicompost (10 ton fed-1) and spraying the high concentration of ascorbic acid (200 ppm). Increasing the addition of vermicompost followed by spraying with ascorbic acid increased the content of the nutrients that benefit tomato plants (nitrogen, phosphorous and potassium), while the sodium content of the leaves decreased
