fertilizer effect on proximate composition and nutritive value of exotic/minor vegetable crops

Purpose: a study was conducted on the effect of single-based fertilizers and compound fertilizers on the nutritive quality potential of lettuce (var. eden), sweet pepper (var. yellow wonder), and carrot (var. bahia). research method: this was accomplished following completely randomized design (crd) with four replications. lettuce, sweet pepper, and carrot were fertilized using 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. findings: compound fertilizer resulted in high fe content in lettuce whiles single 2 treatment was in favour of that in carrot and sweet pepper. single 3 treatment resulted in high ca content in lettuce and sweet pepper whiles single 2 treatment was in favour of that in carrot. compound fertilizer resulted in high mg content in lettuce whiles single 3 treatment was in favour of that in carrot and sweet pepper. crude protein content of lettuce, carrot, and sweet pepper was significantly high in the single- based fertilizer treatments. compound fertilizer treatments recorded high carbohydrate content for lettuce and sweet pepper. all treatments recorded high moisture and high fat content. limitations: no limitations. originality/value: proximate composition patterns were strikingly dissimilar in all test crops.
