Abstract
This study evaluated the effects of BioNiKPhos Bio-fertilizer (NARO BHL BF) on maize growth and yield, with a focus on determining optimal application rates and economic benefits. The research was conducted at NARL Kawanda and AbiZARDI in Arua, using a randomized complete block design (RCBD). Seven treatment levels were applied (T1: control, T2: 5ml, T3: 10ml, T4: 15ml, T5: 20ml, T6: 25ml, T7: 30ml) per 20L of water, across three replications, over two seasons at NARL and one season at AbiZARDI. BioNiKPhos was applied five days before planting to promote bacterial colonization in the soil. The results revealed that application of BioNiKPhos at 20ml per 20L of water significantly improved maize height, leaf length, dry biomass, grain yield, and 1000 seed weight compared to the control, with a remarkable 32% increase in grain yield. Thus, preplanting application of BioNiKPhos at 20ml per 20L of water was found to be effective in enhancing maize yield by improving soil conditions. Highest value cost ratio (VCR) was obtained from BioNiKPhos at 20ml per 20L of water (2.58). The study recommended application of BioNiKPhos at 20ml per 20L of water as the most agronomically and economically optimum for maize compared to the control.
