Abstract

This study was aimed to determine the level of selected metals and nutritional composition of pigeon pea seed collected from seven districts of Wolaita zone. A wet digestion procedure involving the use of mixtures of (69% - 72%) HNO3 and (70%) HClO4 at an optimum temperature and time duration was used to determine metals by using flame atomic absorption spectrometry. Kjeldahl digestion method, Soxhlet extraction and furnace were used to determine nutritional values of pigeon pea, and physicochemical properties of soils were assessed using standard methods. The results showed that the levels of concentration of metals in mg/kg dry weight were ranged 105.17 to 144.07 for K, 8.95 to 12.67 for Mg, 7.74 to 12.27 for Ca, 0.247 to 0.543 for Fe, 0.122 to 0.313 for Zn, 0.061 to 0.432 for Mn, 0.087 to 0.134 for Cu and 0.0011 to 0.00196 for Cr. The proximate composition of pigeon pea was in the range of 19.28% to 25.79% for crude protein, 0.993% to 1.75% for crude fat, 3.75% to 5.31% for ash, 10.65% to 13.73% for moisture, 2.28% to 3.06% for fiber, 54.36% to 60.1% for carbohydrate and 326.8 to 345.23 Kcal for energy. The pH of the soil was in the range from pH 5.09 (strongly acidic) to 6.77 (slightly acidic), EC of the soil ranged from 0.047 to 0.14 dS/m (low), the soil OC level was from 1.6% to 2.42% (moderate), total Nitrogen was from 0.12% to 0.23% (low to moderate), the available Phosphorus content of the soil was from 6.82 to 13.52 mg/kg (low to moderate), CEC value of the soil was from 14.8 to 23.53 meq/100g (moderate). The textural classes of soil were sandy clay loam for all sites except Abela abaya. The study confirmed that pigeon pea was a good source of proteins, carbohydrates, and selected metals such as Mg, K, Ca, Fe, Zn, Mn, Cu, and Cr. The concentration of metals and nutritional compositions of pigeon pea seed were found at a permissible level.

埃塞俄比亚沃莱塔地区栽培的Pigeon Pea(Cajanus cajan)所选金属和营养成分的测定
本研究旨在测定从沃莱塔地区七个地区采集的鸽子豌豆种子中所选金属的含量和营养成分。通过使用火焰原子吸收光谱法,使用在最佳温度和持续时间下使用(69%-72%)HNO3和(70%)HClO4的混合物的湿法消化程序来测定金属。采用凯氏消解法、索氏提取法和加热炉法测定了鸽子豌豆的营养价值,并采用标准方法对土壤理化性质进行了评价。结果表明,金属浓度以mg/kg干重计,K为105.17~144.07,mg为8.95~12.67,Ca为7.74~12.27,Fe为0.247~0.543,Zn为0.122~0.313,Mn为0.061~0.432,Cu为0.087~0.134,Cr为0.0011~0.00196,粗脂肪为0.993%至1.75%,灰分为3.75%至5.31%,水分为10.65%至13.73%,纤维为2.28%至3.06%,碳水化合物为54.36%至60.1%,能量为326.8至345.23千卡。土壤pH值在5.09(强酸)至6.77(微酸)之间,EC在0.047至0.14 dS/m(低)之间,土壤OC水平在1.6%至2.42%(中等)之间,总氮在0.12%至0.23%(低至中等)之间。土壤有效磷含量在6.82至13.52 mg/kg(低至中度)之间,土壤CEC值为14.8~23.53meq/100g(中等)。除Abela abaya外,所有场地的土壤质地类别均为砂质粘壤土。研究证实,鸽子豌豆是蛋白质、碳水化合物和选定金属(如Mg、K、Ca、Fe、Zn、Mn、Cu和Cr)的良好来源。鸽子豌豆种子的金属浓度和营养成分处于允许水平。
