Abstract
Soil acidity problem is one of the bottlenecks to improve crop production in high rainfall regions of Ethiopia in general and in Gozamin District of Amhara region in particular. The aim of this study was to examine the effects of integrated use of lime, manure and mineral P fertilizer on acid soils for wheat production and status of residual soil P. The treatments were factorial combinations of lime, manure and P fertilizer which were laid down in a randomized complete block design with three replications. The field study was conducted on Dystric Nitisols in the 2011 and 2012 main cropping seasons at Enerata Kebele, Gozamin District. Lime application hastened early germination while plant height was enhanced by interaction of lime and P. Most parameters were significantly (p < 0.01) affected by two-way interactions while three-way interactions effect increased grain and straw yield at non-significant (p > 0.05) level. In these interactions lime rates were related in quadratic trend while manure and mineral P related linearly. The combined application of 5 t manure and 2.2 t ha-1 lime increased grain and straw yield by 279% and 187%, respectively over the control treatment through economical analysis result 515 Eth. birr ($28) ha-1 profit obtained due to additional yield obtained. Although all treatments residual soil P were categorized under very low status, it has strong positive correlation (r2 = 0.79) with lime application. The present study showed the combined application of 5 t manure and 2.2 t ha-1 lime was found to be economical feasible to improve wheat yield and yield components and residual soil P of acidic soils of the study area.
