Abstract:
The potential of three (3) organic wastes solely and in combination with NPK (20:10:10)
fertilizer was evaluated on soil chemical properties at the University of Ilorin Dam site, Ilorin,
Kwara State. Randomized Complete Block design in split plot arrangement was adopted using
three treatments at five levels with three replicates. Treatment levels were: 0, 10t/ha, 15t/ha,
10t/ha+NPK and 15t/ha+NPK for Poultry Droppings (PD) and Rice Husk (RH), while Abattoir
Effluent (AE) was at 0, 1.3 t/ha, 2.6t/ha, 1.3t/ha+NPK and 2.6t/ha+NPK. Low Nitrogen Tolerant
Population White (LNTPw) maize was used as test crop. Results showed that TN, P, Ca, Mg,
CEC, ECEC, were significant at p<0.05 for all the amended plots but were higher in poultry
amended plots. The results also showed that sole application of poultry droppings at 10t/ha and
complementary use of poultry droppings and NPK fertilizer at 15t/ha+NPK. Therefore,
complimentary use of poultry droppings and NPK could be recommended for improved soil
productivity. |
