Simultaneous Application Effect Triple Super Phosphate and Powder of Hosphate Rock on Dry Matter Yield and Phosphorus Absorption by Alfalfa

This research has been conducted to determine the main and residual effects of simultaneous application of triple super phosphate and powder of phosphate rock on yield indices and nutrient elements (P,Fe, Zn) concentration in alfalfa(Medicago sativa L.cv Hamedani). The experiment has performed in randomized complete block design by six treatments and three replication on research station of Agricultural and nutural resources research center of shahrekord. the treatments of this study were consist of: T1= TSP, T2=0.8 TSP + 0.2 PR, T3= 0.5 TSP + 0.5 PR, T4=0.2 TSP + 0.8 PR, T5= PR, T6= control
