Abstract
This investigation was carried out during 2018 and 2019 growing seasons on 12- year- old Le Conte pear trees (Pyrus communis L.X Pyrus pyrifolia N.) budded on Pyrus betulaefolia rootstock, planted at 5 × 5 meters apart in sandy soil under drip irrigation system. These study included effected of foliar spray with Mo at 1% and 3%, Fe 1000ppm at and 3000ppm on some Vegetative measurements and Nutritional status. The results showed that, foliar spray with the Mo at 3% and Fe at 1000ppm was the best in some vegetative growth measuremant i.e.(trunk diameter, shoot length, shoot diameter, no.of leaves per shoot and leaf area) and Nutrtional status i.e.(photosynthetic pigment, N, P, K, Fe, Mn, Zn, Ca and Mg). foliar spray with Mo at 3% and Fe at 3000ppm came in the second rank in this respect. Besides, foliar spray with each individual Fe at 3000ppm lonely without Mo, as well as foliar spray with Fe at 1000ppm and Mo at 3% alone were less effective in increasing these properties and subsequently arranged in the third rank in this respect. On the other hand, the untreated trees with any of the investigated treatments was the inferior one in this respect as it recorded the least value of these parameters, followed in ascending order by spraying with Mo at 1% during both seasons of study.
