Abstract:

Turkish dryland agriculture system had good productivity in the sixties with introduction of high yielding cultivars and increase in fertilizer use. However, the sustainability of this system is questioned due to intensive soil cultivations and insufficient supply of crop residues to the soil. Long term (25 years) rotation experiments revealed that suitable crop rotations could replace clean(black) fallow/wheat system. No-tillage could be a sustainable alternative to the current systems. Six year experience with no-tillage technology showed that black fallow can be substituted with chemical fallow which leave all the residue (straw) on the soil surface. The no-tillage is successful in legumewheat rotations. Early results of green manuring experiments were promising in increasing the efficiency of chemical fertilization. Turkish dryland agriculture can move forward through adoption of reduced tillage and right crop rotation systems and green manuring/residue management technologies.
