Farm manure and tillage management are among the importantfactors affecting soil physical properties and crop yield. A fieldstudy was conducted to investigate the residual effect of tillage andfarm manure on N, P and K content in soil and plant shoot in wheat.The experiment was laid out in randomized complete block designwith split plots. Four tillage methods (zero, minimum, deep andconventional tillage) and three farm manure levels (control, FM atthe rate of 10 and 20 Mg ha- 1) were used in the previouscrop/year. Wheat was grown up to maturity and levels of, P and Kin soil and plant were determined. Tillage methods significantlyincreased K content in wheat shoots only, while their effect on K insoil and N and P content both in shoot and soil was non-significant.Farm manure significantly increased N content in wheat shoots, Pcontent in soil and K content both in wheat shoots and soil, while itseffect on P content in wheat shoots and N content in soil was non-significant.
