(1998): Improving the productivity of winter wheat in Iran through rotation of wheat, fallow, soybean and alfalfa and manuring.
Die Bodenkultur, 49, 151-157

The effect of preceding crops on succeeding winter wheat was tested on a rendzic leptosol, 30 km west of Teheran (altitude 1350 m, rainfall 370 mm, average annual temperature 13.6 degrees C). In 1993/94 and 1994/95 the field was maintained twice under fallow and planted with winter wheat, alfalfa, soybean or left fallow in 1995/96. Winter wheat was planted as the test crop in 1996/97 on all plots, with 0 or 5 t per hectar manure in a split plot arrangement in four replications. Both manure and rotation significantly and positively influenced winter wheat grain yield and yield components. Yields were 1.86, 2.75, 4.08 and 4.83 t/ha with manure and 1.43, 2.09, 3.13 and 4.10 t/ha without manure, when followed fallow, winter wheat, soybean or alfalfa respectively.
