Changes in growth, yield and fruit quality of cucumber (Cucumis sativus L.) in response to foliar application of calcium and potassium nitrate under plastic house conditions.

This study was designed to determine the influence of foliar application of calcium and potassium nitrate concentrations (0,10 and 15 mM) on growth, yield and fruit quality of cucumber grown under plastic house conditions. The results revealed that, the higher concentration (15 mM) of each spray solution of calcium and potassium nitrate was superior in […]

Effect of Foliar Spray of Different Potassium Sources on Growth, Yield and Mineral Composition of Potato (Solanum tuberosum L.)

Two field experiments were conducted during 2013 and 2014 winter seasons to study the effect of foliar spray with potassium nitrate, potassium silicate, potassium chloride and mono potassium phosphate at the rates 1000 ppm and 2000 ppm on growth, yield parameters and some biochemical constituents of potato plant (Solanum tuberosum L.). Two samples were taken […]

Potassium Sulfate Foliar Spray Effects on Yield, Quality, and after Harvest for Banana

This study was on banana, where potassium sulphate was used as a foliar spray on banana at three concentrations (0.5% -1.00% and 1.5%) twice after the opening of the last hand (i.e. 7th month after planting), and 30 days later. Number of leaves, total Chlorophyll in leaves, Number of days required for maturation, Average weight […]

The effect of using some sources and types of phosphorus on flowering, fruiting and productivity in some olive trees

This research was in 2014 and 2015 seasons on Picual and Kalamata olive cultivars. Trees were about 15 years old, planted at 6×4 meters apart in a sandy soil, under drip irrigation system at privet orchard located at Cairo –Alexandria desert road. The research aimed to study the independent effects of foliar application with Mono […]
