| Abstract | ||
| Field experiment was carried out during winter season 2018 / 2019 in Mareyout, the agriculture experiment station of the Desert Research Center, south west Alexandria, Egypt to study the influence of foliar application of phosphorous at rates of 0, 1, 2 and 4 kg P/ fed. And the mixture of some microelements (Fe, Mn and Zn) at rates of 0, 150, 300 and 600 ppm / fed. On the growth and productivity of barley grown in calcareous soil under surface irrigation system. Foliar spraying of the treatments were added through three doses, i.e. in tailoring, elongation and budding stages, of barley plants (Giza 123 c.v). Results showed that spraying barley by 4 kg P /fed, combined with 600 ppm /fed of mixture (Fe, Mn and Zn), which were very effective in improving grain, straw and biological yields, which recorded 2.2 , 5.3 and 7.5 ton/fed, respectively. And gave the highest increases yield parameters (plant height, No. of tillers/ m2, No. of spikes/m2 and spike length. Also, this treatment recoded the highest values of nitrogen, potassium, phosphorus, Fe, Mn and Zn as concentration and uptake in both grain and straw of barley plants. It is noticed that, increasing application of P and microelements mixture lead to a significant increases of the studied parameters. | ||
