Effect of some conditioners on properties of soil different texture and emergency and yield of wheat

Abstract

Soils samples were collected from different sites in southern Iraq sedimentary soils of the surface layer depth of 0-20 cm.. The analysis showed that the soils include a wide range of particle sizes distribution such as sandy sandy loamy to Clay texture, the results showed that most soils have ability to form hard surface crust . Soils with a high content of (clay + silt) gave the highest values of modulus of rupture (MOR) (6366-5677) mill bar as Akkad control treatment soils (siltyclay)texture after and before agricultural .Positive and negative linear relationship between Clay and sand with MOR, the correlation coefficient highly significant (r = 0.682) and (r = 0.703), respectively . The biological experience of Conducted agricultural in poet experiment three replicates, the experience of its texture random to determine the impact toughness crust soils surface ratios germination of five soil different texture factory waste and organic material ,left treatment compared each soil without adding. Results showed that the ratios germination inversely proportional to the strength of the surface crust as ranged germination of 18% of the clay soils and 96% of sandy loam soils comparison. Adding Polymeric as conditions to the soil reduce the coefficient of (MOR) and reduced the appearance of rigid surface crust. And differing conditioners gave different germination rates for the same soil and transactions compared with the Control treatment and soils treatment with (Torellat, Brailat, organic matter Control treatment) respectively.
