Foliar spray with potassiumcitrate at 4 g/ ℓ led to a significant increase in number of fruits per plant, yield per plant and total yield per 100m2 in both seasons and improving fruit quality expressed as firmness, color, TSS and vitamin C during storage at 10 oC and 90% RH for 21 days. Spraying sweet pepper Shanghai hybrid with potassiumcitrate at 4g/ ℓ recorded the best values of yield and its components, and improved storability during cold storage for 14 days by reducing weight loss percentage and gave fruits with good color.
