Abstract: The study aimed at evaluating the effect of tillage practice on vegetative growth and yields of
maize and was guided by the following objectives;i) to evaluate the effect of tillage practice on
vegetative growth of maize,and ii) evaluate the effect of tillage practice on maize yield. The
experiment was conducted in two locations; one at the Zonal Agricultural Research and
Development institute in Ngetta Sub County, Lira district and another one in Njeru Town council
in Buikwe district. Maize varieties Longe 10H and Longe 5 were used in this experiment. The
experiment was arranged in a factorial design with 2 tillage practices (conventional tillage, CT
and minimum tillage, MT) as the main factors and 2 maize varieties (Longe 10H and Longe 5H)
as the levels. The results showed that there was significant difference in plant height, stem girth
and leaf width between the two tillage methods.Conventional tillage practice resulted in higher
maize grain yield (figure 8)than minimum tillage (figure 8) although the yield difference
between the two practices was insignificant. If farmers are to adopt minimum tillage practice in
Uganda, they are advised invest in herbicides in order to control the weed |
