Fertilizers are used to improve soil fertility and crop production, but high cost and environmental effects have necessitated cost-effective fertilizer management strategies. A field experiment was setup as randomised complete block design with three treatments (Control – no fertilizer, soil NPK and foliar NPK) to compare the benefits of soil and foliar fertilizers on cucumber yield and income. Yield ranged from 9.8–12.3 kg ha-1 and differed significantly (P < 0.001) across treatments, with the highest in foliar NPK followed by soil NPK and control. Cucumber yield correlated significantly (P < 0.05) with plant height, stem girth and number of leaves. Cucumber fruit length ranged from 16.1–19.1 cm and differed significantly (P < 0.001) across treatments, with the longest in foliar NPK. Plant height ranged from 38.6–70.7 cm and differed significantly (P < 0.001) across treatments, with the highest in foliar NPK, followed by soil NPK and control. Stem girth ranged from 4.9–5.5 cm and differed significantly (P < 0.05) across treatments, with the highest in foliar NPK as compared to control. The number of leaves ranged from 13–16 per plant and differed significantly (P < 0.05) across treatments, with the highest in foliar NPK as compared to control. Number of branches ranged from 12–15 per plant and differed significantly (P < 0.05) across treatments, with the highest in foliar NPK as compared to control. Income ranged from $7,154–9,289 per hectare and differed significantly (P < 0.001) across treatments, with more income for foliar than soil NPK and control. Overall, the foliar NPK fertilizer recorded more yield and profitability than soil NPK.
