Carried out research during the growing season (2014 m) in the halo village of hand dignity - Raqqa on clay soil in order to assess cotton crop response category (Paper 5) to the effect of tillage and mineral fertilizers system and various organic in some of the physical characteristics of the depth (0-30 cm) from the soil and productivity of cotton crop - class (paper 5). Use design dissident sectors arranged randomized complete sectors and three replicates per treatment, and the number of transactions (three tillage systems and six coefficients different fertilization and three replicates per treatment (3 x 6 x 3) = 54 experimental piece. and has represented major transactions tillage systems are as follows: - Agriculture on the skin (no-till) .- plow tillage using Almtrahi flap (0-30) using the CM-hard plow tillage of the soil (chisel plow (.oama secondary transactions are: coefficients (chemical fertilizers and organic): - urea 120 kg N /e (the witness). - urea / 240 / kg N/e - remnants of sheep 30 t/h - remnants of sheep 60 t/h - glaucoma Poultry 10 t/h - glaucoma Poultry 20 tons /h.ajeryt agricultural service operations in all transactions of sowing stage until the harvest stage Most important results that have been reachedtillage using a plow Almtrahi flap to reduce significantly the value of the contributed (bulk density, and a significant increase in the values of both the average value of the total porosity, and the values of average
