A field experiment was conducted at the crop pavilion, Faculty of Agriculture, University of Ilorin, Ilorin in the southern Guinea savannah ecology to determine the effect of NPK fertilizer application on the growth and yield of three cucumber varieties.

The experiment was designed as a 3×5 factorial in RCBD, arranged in split-plots, and replicated three times. The main plots consisted of three cucumber varieties (Marketer, Marketmore, and Poinsett), while the sub-plots were made up of five levels (0, 25, 50, 75, and 100kgNha-1) of NPK fertilizer.

Plant growth parameters (plant height, number of leaves/plant, number of branches per plant, leaf area per plant, number of males, the female and total number of flowers), as well as yield characteristics (dry matter, fruit length, fruit circumference, number of fruits per plant and fruit fresh weight), were measured.

Data were analyzed by the Analysis of Variance, using the split-plots model and significant means were separated by the Least Significant Difference at 5 percent probability level (LSD0.05).

The results showed that the application of the NPK fertilizer appreciably improved the growth performances of cucumber, with 100kgNha-1 being the most outstanding rate while the yield characteristics were not improved with the application of NPK fertilizer.

However, significant variety x fertilizer effects revealed that the application of 100kgNha-1 was best for the three varieties, suggesting in differential nutrient requirements of cucumber varieties.

Conclusively, the application of NPK fertilizer is beneficial for cucumber production, and increasing the rate of application up to the highest level of 100 kg/ha gave the best results vegetatively.
