Abstract :Phosphorus fixation in soils is a big problem, for that, it affects negatively on phosphorus use efficiency of the plant. The amount of phosphorus which had fixed depends on orthophosphate ions and some soil properties. The goal of two experiments [In the first maize insert ignore into journalissuearticles values(Zea mays L.); and the second bread wheat insert ignore into journalissuearticles values(Triticum aestivum L.);] to know the different influence of mono-ammonium phosphate [MAP NH4H2PO4] and di-ammonium phosphate [DAP insert ignore into journalissuearticles values(NH4);2HPO4] fertilizers when were applied in the soil at rates insert ignore into journalissuearticles values(0, 30, 60 and 90 mg P2O5 kg-1); on phosphorus use efficiency under greenhouse condition. Completely Randomized Design insert ignore into journalissuearticles values(CRD); was arranged for both experiments in four replications in first experiment and three in the second. Results cleared that plant dry weight insert ignore into journalissuearticles values(PDW, g pot-1); and plant phosphorus uptake insert ignore into journalissuearticles values(PPU, mg P pot-1); were increased with increasing doses of MAP and DAP fertilizers in both experiments according to control insert ignore into journalissuearticles values(0 ppm);. Furthermore, apparent recovery phosphorus use efficiency insert ignore into journalissuearticles values(ARPUE, %); increased in DAP at maize and decreased in MAP at wheat trial when increasing phosphorus doses. All parameters had highly significantly affected by phosphorus. Also, fertilizers were a highly significant effect on PDW, PPU and agronomic phosphorus use efficiency insert ignore into journalissuearticles values(APUE); in maize and PPU in the wheat trial. Otherwise, interaction insert ignore into journalissuearticles values(F×P); had a highly significantly affected on PPU, physiological phosphorus use efficiency insert ignore into journalissuearticles values(PPUE); and ARPUE in wheat and APUE in maize. Additionally, PDW had a significant effect on interaction. When the MAP and DAP were increasing, that means increased PDW and PPU but MAP is better than DAP. Additionally, the results of the MAP in phosphorus use efficiency are better than DAP too.
