COMPARATIVE ANALYSIS ON ESSENTIAL ELEMENTS IN MORINGA AND SPINACH OBTAINED FROM KWAKWACI FARM AND KANO STATE POLYTECHNIC GARDEN.

This study presents a comparative analysis of essential elements, specifically calcium, magnesium, and nitrogen, in Moringa and Spinach obtained from polluted and unkwakwaci farm s. The aim was to assess the influence of environmental pollution on the concentration of these key elements in these two plant species. Samples of Spinach and Moringa were collected from both Kano state polytechnic Garden and kwakwaci Farm, and the levels of calcium, magnesium, and nitrogen were measured using Palin test photometer. The results revealed significant differences in the concentrations of these elements between the plants from kwakwaci farm and Kano state polytechnic Garden. In terms of calcium, Spinach from the kwakwaci farm had 50 mg/l, while the Kano state polytechnic Garden and kwakwaci farm had 40 mg/l. Moringa, on the other hand, showed a higher concentration of calcium in the kwakwaci Farm (96 mg/l) compared to the Kano state polytechnic Garden and kwakwaci (56 mg/l). Magnesium levels followed a similar trend, with Spinach from the kwakwaci farm showing 46 mg/l, and Moringa from the kwakwaci farm showing 240 mg/l. Nitrogen levels in the samples were also measured, with Spinach from the kwakwaci farm exhibiting a nitrogen concentration of 0.033 mg/l, while Moringa from the Kano state polytechnic Garden and kwakwaci had 0.037 mg/l. These findings suggest that environmental pollution plays a significant role in altering the nutritional composition of these plants, with Moringa showing higher concentrations of essential elements in polluted environments compared to Spinach. The results of this study emphasize the need for monitoring the impact of pollution on agricultural products, as it may affect their nutritional quality and public health. x
