An experiment was conducted to evaluate the effect of soil compaction levels and biochar addition on some soil physical parameters, namely; bulk density, particle density, soil porosity, hydraulic conductivity and infiltration. It included two factors: soil compaction with two levels of 0 and 2 kg and biochar addition with two levels of 0 and 2 %. The results showed that the soil compaction of 2 kg significantly affected in the bulk density, soil porosity, and hydraulic conductivity comparing with the soil compaction 0 kg, with no significant effect on particle density and infiltration. Meanwhile, 2 % biochar addition significantly affected in the bulk density, soil porosity, and hydraulic conductivity compared with 0 % biochar addition, with no significant effect on particle density and infiltration. Moreover, the results showed that the interaction between soil compaction and biochar addition led to a significant effect giving lowest bulk density 0.99 Mg m-3, particle density 2.42 Mg m-3, hydraulic conductivity 1.46 cm h-1, and highest soil porosity 59.20 %, with 0 kg soil compaction and 2 % biochar, but lowest infiltration 8.10 cm h-1 with 2 kg soil compaction and 2 % biochar.

A field experiment was carried out during season 2021-2022 in the fields of university of diyala College of Agriculture Department of Soil Sciences and Water Resources in a sandy loam soil texture. The experiment was designed according to of randomized complete block design (R.C.B.D), the experiment included two factors, the first factor perlite used by two levels they are wihout perlite (P0) and (2%) (P1), the second factor soil compaction and by two levels without compaction (C0) and compaction by 2 Kg (C1). The result show rate increases perlite from (P0) to (P1) led to significant increased the percentage of gravimetric moisture of (16.30 to 24.50)% respectively

A factorial field experiment was conducted in the fields of the college of agriculture / Tikrit university in sandy loam texture soil by using (RCBD) to study the effect of potash fertilizer and the type, source of zinc in the grain yield of wheat. The experiment included two factors the first potassium fertilizer was four levels (0, 80, 160 , 240) Kg K ha-1 as potassium sulphate and the second factor is zinc fertilizer added from two sorouce: the mineral zinc sulphate ZnSO4.7H2O and chelate zinc Zn-EDTA with by five levels of the two fertilizers: control(Zn0) , (10 , 20) Kg mineral

A field experiment was carried out at the Research Station of the College of Agriculture / Tikrit University during the season 2019-2020. To study the effect of different levels of potassium fertilizer, level and source of zinc on nutrients uptake for wheat crop in gypsiferous soil According to a randomized complete block design (RCBD). The experiment included (60) treatments resulted from combinations of two factors, the first potash fertilizer was added at four levels (0, 80 ,160 and 240) Kg K

Field experiment was conducted during the season 2013-2014 in station of Agriculture college – Tikrit University to study the effect of different levels of phosphate and magnesium fertilizers on yield of wheat plant in gypsiferous soil. using RCBD design with two factors. The first was phosphate fertilizer which was added at four levels (0, 50 ,100 ,150 Kg P.ha-1) as TSP , while the second factor was magnesium fertilizer was added at three levels (0, 60, 120 Kg Mg.ha-1) as magnesium sulphate (MgSO4.7H2O). Result of this study indicated that the quantity of available – P and Mg in soil bedon sowing 4.22 and 9.92 mg.Kg-1 respectively and it was below the critical level for plant requirement. Application of P- fertilizer significantly increase grain yield while Mg- fertilizer significantly increase grain yield only at Mg1 level (60 Kg Mg.ha-1). maximum yield was 3246.00 Kg.ha-1 at P2Mg1 treatment. The increase in grain yield was mainly due to the number of grain.ear-1 and secondly to number of ear.m-2 and weight of 100 grain.
