An experiment was conducted at the experimental site of the Institute of Agricultural Research and Training, Moor Plantation, Ibadan, Nigeria to examine the effect of different combination levels of OBD organic based and 300 kg/ ha NPK fertilizers on viability and fungal incidence of harvested maize (Zea mays) seeds. Six treatment combinations of OBD and NPK fertilizers were applied as a split plot in a randomized complete block design in three replicates. The treatment levels were OBD-plus organic fertilizer at 5t/ha (OBD5), 10t/ha (OBD10) and 15t/ha (OBD15), and in combination with NPK 15-15-15 mineral fertilizer applied at 300 kg/ha: (OBD5NPK, OBD10NPK and OBD15NPK). Fertilizer NPK applied at 300 kg/ha, served as control treatment. Twelve weeks after planting, the seeds were harvested, shelled, dried and stored for 4 weeks at room temperature. They were cultured weekly usi.. View more»
