Abstract

Two experiments werecarried outduring winter seasons of 2011/2012 and 2012/2013 in a Private Farm at Al-Salhia El-Jadida, Region, Sharkia Governorate, and Laboratory of Handling of Vegetable Crops Department, Horticulture Research Institute, Agriculture Research Center, Giza, Egypt, to study the effect of foliar spray with potassiumcitrate at three levels (Zero, 2g/ ℓ and 4 g/ ℓ) on yield and its components, fruit quality and storability during cold storage of some sweet pepper hybrids (Drasena and Shanghai) grown under plastic house conditions.                                                                        There were no significant differences between the two hybrids with respect to yield and its components. 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. Conclusively, from the previous results of this investigation, it could be concluded that spraying sweet pepper Shanghai hybrid with potassium citrate at 4g /ℓ was sufficient to produce the highest yield and its components, and improved quality and storability of fruits.
