Abstract
This work was conducted at a private Farm in El-Kasr city, El-Dakhla Oasis, New Valley Governorate, during 2022 and 2023 seasons to study the effect of two sowing dates (1st and 20th February), foliar spray with some safe materials, i.e., salicylic acid (SA) at 0.5 and 1.0 mM, ascorbic acid (AsA) at 50 and 100 ppm, and potassium silicate (KSil) at 4 and 8 ml/l, beside untreated control, and the interaction between them on growth, yield and fruit quality of watermelon (cv. Aswan F1). The interaction between sowing watermelon on 20th Feb. and foliar spray with KSil at 8 ml/l recorded the highest values of vegetative growth parameters and dry weight/plant, nitrogen, phosphorus and potassium % in leaves and average fruit weight, fruit quality, i.e., total soluble solids, total and reducing sugars, lycopene concentration and ferric reducing antioxidant power assay. While the interaction between sowing on 20th Feb. and spraying plants with AsA at 50 ppm gave the highest total yield/faddan without significant differences in the interaction between sowing at the same date and spraying plants with KSil at 8 ml/l in both seasons. The relative increase in total yield/faddan were about 71.96 and 70.93% for the interaction between sowing on 20th Feb. and spraying plants with KSil at 8 ml/l and 73.83 and 72.40% for the interaction between sowing on 20th Feb. and spraying plants with AsA at 50 ppm over sowing date on 1st Feb. and (spraying plants with distilled water) in the 1st and 2nd seasons, respectively.
