Thank you very much, but the title of the paper indicates that this for durum wheat, is it be effective for hexaploid wheat in the soil conditions like that of Pakistan..

Ok, Thanks for your proper guidance.....

I do not think that there is a single "best" technique. Suitable land preparation techniques need to be designed based on the local agroecological conditions (especially soil-climate interactions). One way to do this consists in assessing the diversity of techniques already used by wheat growers in the area (they are the result of their, sometimes very long, empirical experience) to identify the superior ones under different conditions.
