A major constraint faced by farmers is managing plantains in the nursery and obtaining high quality planting materials. Methods: A study was carried out to compare the effects of a locally made biofertilizer – ‘Njoku’ with pesticide properties, foliar fertilizers and a synthetic inorganic fertilizer on plantain growth and infestation in the nursery. A randomized complete block design of six treatments with four replications was used. The treatments (T) per plant were as follows; T1 = Control (no application), T2 = 5g of biofertilizer (Njoku), T3 = Inorganic NPK (20-10-10), T4 = 2.5g of Counter® (terbufos) + 2.5g of NPK (20-10-10), T5 = 50ml of Radix Tim® solution + 2.5g of biofertilizer and T6 = 100ml of Radix Tim® solution. Results: The vegetative growth parameters (Plant height, leaf number, leaf area, and collar girth) of the fertilized plants were significantly higher as compared to the control plants. The highest mean plant heights were recorded in T4 (21.88cm) and T5 (21.5cm) while the least mean plant height was from T1 (9.82cm). The highest mean leaf area of 289.12cm2 and 282.37cm2 were recorded respectively from T5 and T6. T4, T5 and T6 had the same mean number of leaves (4 leaves) while T2 and T3 had mean number of leaves of 3. The highest mean collar girth of 5.6cm and 5.5cm was recorded in T5 and T6 respectively and the mean collar girth for T2, T3, T4, T5 and T6 never differed significantly. T2 harboured many types of pests but recorded the least mean number of pests while T4 harboured the highest number of snails followed by T6 and T1. Conclusions: Due to the high cost and potential environmental hazards posed by synthetic chemicals, T5 (a combination of reduced doses of the biofertilizer and Radix Tim®) is most suitable for the growth and maintenance of plantain plantlets in the nursery.
