Abstract:
An experiment was setup in Makera in 2014 and 2015 cropping seasons toinvestigate the effects of different soil-incorporated organic manure and mineral fertilizer inputs on maize yield components, and soilexchangeable bases (cations).The experiments were laid out as 3 x 4 x 2 factorial in a split-split plot design with three replicates.Data were analysed using Analysis of Variance (ANOVA) at p =.05. Albizialebbeckbiomass had higher mean values of N (3.24%) and C (18.64%)contents and lower mean value of C: N ratio (5.75) than Parkia. Albiziabiomass significantly improved grain yield and harvest index than Parkia. Meanwhile, incorporation of biomass did not have significant effect on soil exchangeable sodium and potassium.It is therefore concluded that incorporation of Albizia with up to 120 kgNha-1 rate improved the yield components of both DMR-ESR-7 and 2009 EVAT maize varieties.
