A study was conducted to ascertain the effect of single-based fertilizers and compound fertilizers on some minor/exotic vegetable crops cultivated for the fresh market using lettuce (var. Eden), carrot (var. Bahia), and sweet pepper (var. Yellow wonder) as reference/test crops, with the objective to determine food yield of each test crop. Done through diagnostic and field studies, Randomized Complete Block Design with four replications was used. Lettuce, sweet pepper, and carrot were tested on 71 kg, 100 kg, and 128 kg of ammonium sulphate (20.5 % N, 23.4 % S) /ha, 350 kg of NPK (15-15-15) /ha, and Control/No fertilizer application; 81 kg, 100 kg, and 138 kg of 6-24-12 NPK/ha, 225 kg of NPK (15-15-15) /ha, and Control; and on 43 kg, 71 kg, and 100 kg of 10-10-30 NPK/ha, 225 kg of NPK (15-15-15) /ha, and Control; respectively. Single-based fertilizer treatments recorded significantly higher food yield at p ˂ 0.05 when compared to Compound fertilizer treatments, and to Control. Maximum application rates (128 kg of ammonium sulphate (20.5 % N 23.4 % S) /ha; 138 kg of 6-24-12 NPK/ha; and 100 kg of 10-10-30 NPK/ha, respectively for lettuce, sweet pepper, and carrot) of the respective single-based fertilizer treatments for the different test crops recorded the highest food yield at p ˂ 0.05, portraying strikingly similar pattern of food yield changes. Higher single-based fertilizer application rates could be added in different trials to ascertain the optimum application rates since all maximum application rates recorded the highest food yield in the present study.
