Two field experiments were conducted at EL-Kharga Oasis, Research Station, Desert Research Center (D.R.C.), New Valley Governorate, South Western, Egypt, during two winter growing seasons of 2015/ 2016 and 2016/ 2017 to study the effect of poultry manure extract (PME) as a foliar application (1, 2, 3 and 4 m/ fed.) compared with control and soaking grains in selenium (Se) on growth, yield and its components and chemical composition of wheat. Increasing PME rates from 1 up to 4 m/ fed .increased significantly all characters under study growth, yield and its components and chemical composition except % selenium compared to zero PME in both seasons. The differences between the two levels 3 and 4 m/ fed. of PME were not significantly for plant length (cm), no. of tillers/ plant, no. of leaves/ plant, plant fresh weight, plant dry weight and all yield and its components in both seasons. The highest values of growth parameters, yield and its components were obtained by spraying of wheat plants with 3 m PME / fed.in both growing seasons, while, chemical composition were obtained by 4 m PME/fed.in both growing seasons. Increasing Se rates by soaking grains from 5.0 up to 10 mg Se/ l, increased all parameters under studied except, number of leaves/ plant and flag specific leaf weight F.S.L.W. mg/ cm, spike length (cm) and number of spikelets/ spike and total carbohydrates % compared to zero selenium in both seasons. All concentrations of Se percentage of all chemical composition were significantly increased in both seasons. However proline were significantly decreased compared with the control in both seasons. The highest values of these parameters were obtained by soaking grains with 10 mg Se/ l while, the differences between this level and the high level 20 mg Se/ l were don’t significant in both seasons. Furthermore, the results showed that the interaction between PME foliar application and grains soaking with Se rates had a significant effect on all parameters studied in both seasons, except no. of leaves/ plant, flag specific leaf weight mg/ cm and grains and % potassium were insignificant in the two growing seasons. The maximum increments for growth parameters, yield, its components and chemical parameters were obtained by spraying wheat plants by 3 m PME/ feddan and grains soaking by 10 mg Se/ l in both seasons compared with the control except, leaves content of proline had the opposite trend of the other parameters. It could be concluded that grains soaking by Se (10 mg Se/ l) and foliar spraying of PME at 3 m/ fed. At every 15 days after sowing in most cases led to increase wheat productivity under New Valley conditions.
