The factorial combination of lime, manure and P fertilizer was applied in 2011 season to examine the extent of residual effects on 2012 season’s wheat yield and soil properties. In 2012 season each plot was divided into two, one plot received the same treatment and the remained was allowed to produce wheat residually. The residual value of the treatment computed based on the standard procedure. The residuals of lime and manure significantly increased wheat yield, while reapplication of lime and P fertilizer showed significant influence on crop grain yield. Thus, reapplied lime had negative response on wheat yield while positively to reapplied manure and P. The residuals of lime and manure were increased soil P but manure improved soil organic carbon. Residual values for grain yield and soil P were significantly increased by integrated use of lime and manure. Residual of combined use of 2.2 t ha-1 lime and 10 t ha-1 manure gave 0.58 t ha-1 more grain above the control. However, maximum residual value for soil P was observed on combined use of 3.3t lime and 10t ha- 1 manure, whereas P residual value of combine use of 2.2t lime and 10t ha- 1 manure treatment was 0.60. Therefore, the residual of combine use of 2.2t lime and 10t manure improve wheat yield and soil properties.
