Summary

The potentials of compost supplemented with jatropha cake as soil amendments were evaluated under screenhouse at Kwara State University. Maize (variety EVDT-W99 STR) was used as test crop. The experiment consisted of two consecutive experiments in which residual effect was observed in the second experiment. The treatment were; control (Zero addition), NPK 15 –15-15 at 60 kg N/ha, 30% Grade B + 70% Jatropha cake at 1.5, 2.0 and 2.5 t /ha, 40% Grade B + 60% Jatropha cake at 1.5, 2.0 and 2.5 t /ha, 50% Grade B + 50% Jatropha cake at 1.5, 2.0 and 2.5 t /ha, 60% Grade B + 40% Jatropha cake at 1.5, 2.0 and 2.5 t /ha . The design was completely randomized design replicated three times. Results obtained showed that 50% Grade B + 50% Jatropha cake greatly influenced growth parameters of maize at first and second cropping. The 50% Grade B + 50% Jatropha cake treatment gave the highest Nitrogen, phosphorus and potassium uptake value; 13.28, 0.32 and 14.60 mg/pot respectively at second planting which differed significantly from all other treatments. The study showed that jatropha cake supplemented with compost at 2.5 t/ha gave higher growth parameters and nutrient uptake when compared with NPK at second planting.
