Abstract EN
A field experiment were conducted in Al-Najme field's bergessa region, which is located in Zubair district Basrah governorate, in spring season 2016.
The soil texture was Loamy Sand.
The aims of the experiments are to study the effect of different levels of sludge and incubation periods on some physical and chemical properties of the soil during the growing stages of sorghum crop (Sorghum bicolor L.) (middle of the season, 40 days from the sowing dates) and the end of the growing stage, after the harvest and depths of application (0-30) cm (d1) and (30-60) cm (d2) in addition to the growing and production parameters.
The sludge factor includes five levels 0 (S0), 25 (S1), 50 (S2), 75 (S3) and 100 tons ha-1 (S4).
The incubation before seeds sowing factor included three levels namely, 30 (T1), 60 (T2), and 90 (T3).The statistical design used R.C.B.D.
The field area was divided into three equal areas blocks The blocks were smoothly leveled .
Each block was divided into 15 units.
The treatments were randomly distributed in each block.
The sorghum seeds were sown in row in 1/4/2016.The irrigation water was added according to the reduction in the water of the basin due to evaporation.
The irrigation water amount was equal to 100% of the amount evaporated plus 20% as leaching requirement.
Crop harvesting was carried out in 10/7/2016.The results of the experiment showed the followings: Soil water content (pw) significantly increased due to addition of sludge .S4 recorded the highest value of pw while S0 recorded the lowest value.S1, S2, S3 recorded medium value of pw at mid and end stages of crop growth.
Incubation period of 90 days surpassed 30 and 60 day periods at mid and end stages of growth.d2 significantly surpassed d1in increasing pw, where as pw decreased at the end of growth stage compared with the mid stage.
The sludge significantly increased MWD at mid and final stages of growth of sorghum crop.S4 and S3 recorded the highest values while S0 recorded the lowest values of MWD.
MWD values also increased with incubation periods while decreased with depth of application the final stage of growth gave higher values of MWD compared with mid stage
