### Effect of OMET Growing Technique on Elemental Nutrient Content in Okra Leaves and Pods  
The protein content was significantly affected by the OMET growth technique in okra pods and leaves. Hence, samples grown under OMET contained higher protein levels in comparison to non-OMET. Furthermore, the levels of protein in the leaves were more than that detected in the pods, as shown in Table 2.  
Evaluating the effect of the OMET growing technique showed a significant (\(p\leq 0.05\)) impact on the mineral composition of okra. The results showed that elemental nutrients, including calcium (Ca), potassium (K), magnesium (Mg) and phosphorus (P), were predominant attributes for the nutritional status of okra leaves and pods. The highest content of Ca (237 mg/kg), Mg (163 mg/kg), K (110 mg/kg), and P (6.6 mg/kg) was recorded in OMET leaves, whilst the lowest contents for Ca (49 mg/kg), Mg (36.6 mg/kg) and P (4.8 mg/kg) were recorded in okra non-OMET pods, except for K (110 mg/kg) which recorded the lowest content in the leaves of non-OMET (Table 2). Thus, this suggested the great impact of OMET on enhancing the macronutrient contents. These macronutrients (calcium, potassium, and magnesium) were found in okra, and they contributed 8%, 9% and 14%, respectively, of the daily required nutritional value [34]. Calcium is well known for its function in maintaining bone and teeth health but is also critical to cell signaling, blood clotting, muscle contraction, and nerve functions. Dietary potassium intake has been demonstrated to significantly lower blood pressure in a dose-responsive manner in both hypertensive and normotensive individuals in observational studies [35]Micro elemental nutrients, including (in descending order) selenium (Se), sodium (Na), zinc (Zn), iron (Fe), and molybdenum (Mn), were studied, and there were significant (\(p\leq 0.05\)) differences among the studied samples. The results pointed out OMET-grown pods and leaves as exhibiting similar and the highest contents of Se (12.2 and 12.8 mg/kg) and Na (6.2 and 6.8 mg/kg), which were slightly higher than Se (11.8 mg/kg) and two-fold higher than the Na (3.7 mg/kg) content found in non-OMET leaves. OMET-grown leaves maintained the highest contents of Zn, Fe, and Mn, which were recorded to be up to three-fold, six-fold and two-fold higher than the mean values presented in non-OMET pods, as shown in Table 2. In this study, nutritional elements (in descending order): Ca, K, P, Mg, and NA were predominant in okra leaves and pods, irrespective of the growing technique (OMET). These results were similar to those reported by [PERSON] et al. [35], who stated that severe drought conditions of up to 30% water application increased Ca and Mg in _Amaranthus curentus_ species. The same study reported an increase in the contents of Zn, Na, P, and K with 60% of water availability. According to [PERSON] et al. [36], moderate deficit irrigation on cowpeas increased the carbohydrate and fiber content due to water availability around the root surface. These reports accounted for the impacts of water availability on okra nutrient availability. On the other hand, multichaping using plant materials such as increased N, P, K, Ca and Mg nutrient contents in okra leaves [14]. Therefore, different cropping systems affected the nutritional composition. According to [PERSON] et al. [15], plastic mulder the _Elaes guineensis_ (Jacq.) canopy reduced to ash, crude protein, and carbohydrates compared to the canopy without multichaping. In addition, different multichaping materials, including _Pueraria phaseoloides_, _Mucuna pruriens_, _Pennisetum pur-pureum_, _and Panicum maximum_ impacted the mineral element composition such that nitrogen, phosphorus, potassium, calcium and magnesium all increased in comparison to the no-muld treatment [15]. In this study, the OMET growing technique maintained higher contents of the minerals than in non-OMET.
