A field experiment was conducted for three years to study the effect of farm wastes and organic manures on soil properties, nutrient availability and yield of rice and wheat on sodic Vertisols. The treatments were pressmud, dried biogas slurry, FYM, and wheat straw. Cropping sequence followed was rice in kharif and wheat in rabi season. All the treatments increased the y)eld of both the crops significantly over control. The treatment FYM @25t ha−1 plus pressmud @20 t ha−1 was the bestfor increasing yields of rice and wheat. In general, all the treatments decreased the pH and ESP of the soil. The infiltration rates increased due to application of organic wastes and manures. All the treatments increased the status of organic carbon, available N, P andK of soil. FYM plus pressmud was also the best in this respect.
