The solutions varied in the amount of NPK (20-10-10) and granules (25 g, 50&nbsp;g, 75 g, 100 g, 125 g and 150 g, respectively) dissolved in water containing micronutrients. The growth media were M<sup>25</sup>NPK, M<sup>50</sup>NPK, M<sup>75</sup>NPK, M<sup>100</sup>NPK, M<sup>125</sup>NPK, M<sup>150</sup>NPK, and Control. Two-week old seedlings of fluted pumpkin raised using River-sand were transferred into the growth media; in four replicates. The nutrient (proximate composition, vitamins, and amino acids) and minerals were determined 5 weeks after planting (WAP) following standard procedures. Among the growth media, fluted pumpkin grown in M<sup>125</sup>NPK medium had the highest energy level (1622.12&nbsp;KJ/100&nbsp;g) while the lowest energy content (1437.43 KJ/100g) was recorded at M<sup>25</sup>NPK medium. Fluted pumpkin grown in M<sup>25</sup>NPK medium had the lowest percentage crude fibre content, crude fat, fatty acid when compared with other growth media. The leaves grown in M<sup>75</sup>NPK medium had the highest value for total vitamins (water-soluble and fat-soluble). The percentage ratio of EAA to NEAA for the growth media was Control (42.33:57.67), M<sup>25</sup>NPK (38.88:61.12), M<sup>50</sup>NPK (40.45:59.55), M<sup>75</sup>NPK (42.06:57.94), M<sup>100</sup>NPK (41.04:58.96), M<sup>125</sup>NPK (45.97:54.03) and M<sup>150</sup>NPK (41.54:58.46). The results recorded indicated that the proportion of the minerals varied in the hydroponic solutions. The nutrient contents of fluted pumpkin leaves grown in the NPK 20-10-10 media varied at <em>P ≤ 0.05</em>. The proportion of mineral elements in fluted pumpkin leaves grown under different concentrations of NPK media at 5 WAP varies in their concentrations.</p> ER -
