Two field experiment was carried out in the feed crop studies station of the Ministry of Agriculture - Haditha agriculture division located in the village of Sakran - Haditha district 260 km west of Baghdad. The location lies on longitude 42 22' 21'' east and longitude 34 08' 23'' north, and 80 m above sea level, On the ground dimensions (21 x 30 m) for each experiment, during the autumn season 2018. The aim of this study is to find out the role of soil surface crusting and its relationship with tillage pattern, irrigation interval and its relationship with soil moisture content, under surface and drip irrigation methods. The treatments of each experiment were distributed individually using Split-Plot Design, with three replication. Transactions were distributed randomly, with each experiment included two experiment on six treatments using zero tillage mode T0, minimum tillage T1 and conventional tillage T2 and two irrigation intervals are two days I1 and four days I2. The results showed, Zero tillage of both irrigation methods (surface and drip irrigation) and two-day irrigation interval resulted in more soil moisture content compared to conventional tillage, Conventional tillage reduced the soil penetration resistance by half at the same percentage of water. for all experiment treatments and both irrigation methods compared with zero tillage and minimum tillage, where the soil penetration resistance by using conventional tillage was 0.5 kg cmˉ² and at 30% pw. The results showed that the longest height and the highest dry root weight was for T0I2 treatment reached to 0.33m and 14 gm, respectively when drip irrigation method was used, while the root length for the T1I1 treatment was 0.29 m and the highest dry root weight of 13 g was for T2I1 treatment when drip irrigation method was used also.
