Effects of Agroforestry Trees Biomass and Urea on Maize Tasselling and Silking Production

Agroforestry system relies heavily on the choice of suitable tree species that should offer diversity of benefits and show compatibility with food crops. A 3 × 4 × 2 factorial design in a split-split plot design was used for this experiment in three replicates for two years. The considered factors were; biomass species (Albizia lebbeck and Parkia biglobosa, and control) as main plots, four rates of nitrogen (0, 40, 80, 120 kg N ha-1) as sub-plots, and two maize varieties (DMR-ESR-7 and 2009 EVAT) as sub-sub plots. A. lebbeck (45.3, 52.9) attained early days to 50% tasselling and silking than P. biglobosa (46, 53.9) in combined means respectively. It is therefore, concluded that incorporation of A. lebbeck with application of fertilizer from 40 kg N ha-1 to 120 kg N ha-1 rate into the soil improved the production of tasselling and silking of 2009 EVAT over DMR-ESR-7 maize variety. And the combinations of Albizia and varieties of maize shortened days to 50% tasselling and silking than Parkia.
