cultivated on different soil texture types, sandy clay loam, silty clay loam, clay loam, loam, and control soils, were evaluated for proximate compositions, antinutrients, vitamins, and mineral composition with plant age using standard analytical methods. Accumulation of trace elements using translocation factor was studied to determine their toxic levels in plant tissues. Data were analysed by ANOVA and results expressed as means and standard deviation. Ash content, crude fibre, protein, alkaloid, phytate, and saponin ranged between 11.4 and 12%, 19.24 and 19.95%, 34.23 and 38.98, 42.08 and 45.76 mg/ml, 0.84 and 1.17%, and 94.10 and 97.00%, respectively. Vitamins A, C, and B were present in high quantity. Macro- and micronutrients recorded showed that is a potential reservoir of minerals. Accumulation of micronutrients was observed to be the highest at the flowering stage between the 4th and 5th weeks after transplanting. Plants cultivated on clay loam, silty clay loam, and loam soils accumulated elevated nutritional compositions and abundant antinutrients. However, the accumulated trace metals in the plants are within the recommended safe levels. All nutrient values are in the recommended requirements for daily consumption.
在不同土壤质地类型（砂质粘壤土、粉质粘壤土、粘壤土、壤土和对照土壤）上种植的作物，采用标准分析方法，对其近似成分、抗营养物质、维生素和矿物质成分随植株年龄进行了评估。利用转运因子研究了微量元素的积累情况，以确定它们在植物组织中的毒性水平。数据通过方差分析进行分析，结果以均值和标准差表示。灰分、粗纤维、蛋白质、生物碱、植酸盐和皂苷的含量分别在11.4%至12%、19.24%至19.95%、34.23至38.98、42.08至45.76毫克/毫升、0.84%至1.17%和94.10%至97.00%之间。维生素A、C和B含量很高。记录的大量和微量营养素表明，该作物是一种潜在的矿物质储存库。观察到微量营养素的积累在移栽后第4至5周的开花期最高。在粘壤土、粉质粘壤土和壤土上种植的作物积累了较高的营养成分和丰富的抗营养物质。然而，植物中积累的微量金属在推荐的安全水平范围内。所有营养成分值均在每日消费的推荐需求量之内。
