Le Conte (Pyrus communis, L.) budded on Pyrus communis rootstock, uniform in vigor, thirteen years old, grown in sandy soil spaced at 4x4 m, under drip irrigation system in a private orchard located at El-Tall El-Kepeer, Ismailia Governorate, Egypt. Trees were foliar sprayed by five mineral iron concentrations (0.0, 250, 500, 1000 and 2000 ppm) as ferrous sulphate (FeSO4.7H2O) form at two times (Mid May and June) during successive seasons 2014 and 2015. This study was conducted with the aim to examine the response of leaf chlorophyll content, active iron, nutrient status, yield components quantity and quality of Le Conte pear trees to foliar feeding of iron concentrations as well as to evaluation the current status of foliar fertilization... |
