Effect of Calcium Nitrate, Potassium Nitrate and Anfaton on Growth and Storability of Plastic Houses Cucumber (Cucumis sativus L. cv. Al-Hytham)
Majeed K. Abbas Al-Hamzawi

Abstract:
This experiment was conducted during the period of December 2008 to May 2009 using cucumber (Cucumis sativus L. cv. Al-Hythum). Three concentrations of Anfaton; 0.00, 600 and 1000 mg L¯1 and five concentrations of spray solutions; 0.00 mM (control), 10 and 15 mM of Ca(NO3)2 and 10 and 15 mM of KNO3 in addition to the combination of anfaton and the two nutrients were used. The results revealed that the higher concentration of anfaton and both concentrations of each spray solution were superior in their effect on plant vegetative characters. Maximum flowers number was recorded by the application of KNO3, while maximum fruit set was obtained due to the use of anfaton at 1000 mg L¯1. Dry weight increased due to spray with the two nutrients. All treatments significantly enhanced cucumber productivity especially at the higher concentration of anfaton and KNO3. Nitrogen, phosphorous, potassium and calcium content increased as the concentration of anfaton increased. The highest nitrogen percent and calcium content were recorded due to the use of KNO3 at 15 mM while the highest phosphorous and potassium content was obtained due to the use of 10 and 15 mM of Ca(NO3)2, respectively. Combination of the higher concentration of anfaton and higher concentration of each nutrient revealed a pronounced effect in most of studied characters. Ca(NO3)2 treatments produced the least weight loss compare to KNO3 treatments. Potassium nitrate at both concentrations was the best in keeping the Total Soluble Solid (TSS) at higher levels. Also, all nutrients treatments reduced electrolyte leakage from fruits compare to control especially the Ca(NO3)2 treatments.
