Abstract
Field experiment was conducted during the season 2018-2019 in research station of Agreculture college – Tikrit University to study the effect of different levels of phosphate and magnesium fertilizers on grain yield of wheat plant at two gypsiferous soils with different contents 5% and 15% gypsum, using RCBD design . Magnesium fertilizer was added ) MgSO4.7H2O ( in three levels ( 0 , 60 , 120 Kg Mg.ha-1 ) and phosphate fertilizer ( TSP ) was added at four levels which was calculated from adsorption isotherm curves at suggested phosphorous concentration (0.00, 0.30 , 0.40 μg P. cm-3 )at the three levels of Mg-fertilizers. Result of this study showed that addition of Mg and P-fertilizers significantly increased grain yield and yield components at the two locations, The P-Conc. ( 0.3 ) gave the highest yield at Mg1 and P1 levels . Highest yield was at P1Mg1 treatment ( 300 kg TSP..ha-1 + 60 Kg Mg.ha-1) with value ( 3278.85 and 3355.77 kg grain.ha-1) at 5% and 15% gypsum respectively .The highest level of phosphate fertilizer ( P3 ) and Magnesium ( Mg2 ) decreased grain yield at the two location . The results indicated that the addition of Mg-fertilizer at Mg1 level and P – fertilizer at P1 and ( 0.3 P-Conc. ) was decreased the phosphate fertilizer requirement 200 Kg TSP.ha-1 at 5% soil and more than 250 Kg TSP.ha-1 at 15% location compared with out addition of Mg-fertilizer ( Mg0 ) and at P2 level which corresponding to ( 0.4 P-Conc. ) The increase in grain yield was mainly due to weight of 100 grain and the number of ears.m2 .
