ABSTRACT

Field experiments were carried out to study the effect of tillage method on soil organic matter on yield of maize under rain-fed conditions on a sandy loam soil of Michael Okpara University Of Agriculture, Umudike, Nigeria. The field was divided into four blocks, in which each block was assigned to four tillage treatments; ploughing alone (P) , harrowing alone, (H), ploghing and harrowing alone, (PH) and no-tillage (NT). The four tillage treatments were randomly distributed according to split plot arrangement with randomized complete block design. The rainfall and temperature data were collected from National Root Crops Research Institute, Umudike meteorological station. The result of these experiment were subjected to statistical analysis using the ANOV A Model. Soil moisture content was higher with a corresponding average values of23.4% in ploughing alone (P) and harrowing alone with least corresponding average values of 6.0% compared with other tillage treatment. Generally, for all the parameters determined from soil analysis except bulk density and porosity, was not significance at 0.05 level of confidence due to tillage treatments. Soil tilled two times (ploughing and harrowing alone, PH) produced significanty higher yield than other tillage treatment. Fresh and dry weights of maize were not significantly affected by different treatment combinations. In general, result shows that the tillage effect leads to an increase in soil fertility, free air circulation in the soil and moisture retention capacity for maize growth. Following these observation, disc ploughing alone is most recommended for Umudike soil following by disc harrowing alone.
