Assessment of important minerals in tomato genotypes in Meghalaya, India
This study assessed the nutritional profile of tomatoes grown in various parts of Meghalaya, an Indian plateau state distinguished by a temperate climate conducive to year-round tomato cultivation. The investigation was conducted using a completely randomised design (CRD) to assess nutritional components. Concentrations of phosphorus, sodium, potassium, and selenium were quantified utilising inductively coupled plasma mass spectrometry. With the exception of the Mawkyrwat genotypes, the levels of phosphorus, sodium, potassium, and selenium were found to be below the safety limits established by the US Department of Agriculture. The results revealed that the highest concentrations of sodium and phosphorus were found in the genotypes from Nongpoh village; the maximum levels of potassium were noted in the genotypes from Jowai; and the highest selenium content was detected in the genotypes from Tura. The study indicates favourable potential for food safety and agricultural nutrition. Meghalaya possesses the capacity to become a major supplier of nutrient-rich genotypes through continuous tomato growth, hence improving agribusiness and local food security.
