This study aimed to evaluate the quality of water; some minerals andphytic acid content in some legume seeds. All samples obtained fromElseleim Agricultural Scheme, north Sudan state. Sixteen water samplesfrom wells, tanks, hand pumps and the river Nile were collected insterilized plastic bottles and subjected to laboratory analysis to estimatetheir physical and chemical properties, these sources used for drinkingfor human and animal as well as irrigation in the field site. On the otherhand, minerals and phytic acid were estimated in the seeds of cowpea(Vigna unguiculata), chickpea (Cicer arietinum), pigeon pea (Cajanuscajan), faba bean (Vicia faba), white bean (Phaseolus vulgaris), lablabbean (Lablab purpureus), field pea (Pisum sativum) and chickling(Lathyrus sativus) that irrigated from the same water sources. Theresults showed that pH, odor, taste, electric conductivity, ammonia,nitrate, nitrite, sulfate, alkalinity, cations, anions and heavy metals inwater samples were within the safe limit according to World HealthOrganization, 1993 and Sudanese Standards and MetrologyOrganization, 2002. However, significantly (P<0.05) high levels ofarsenic (0.1mg/l); Fe (0.3 mg/l) and total dissolved solids (156 mg/l)were detected in the River Nile water sample. All the estimated valuesof the total hardness of the water samples collected from hand pumps,tanks and wells were higher than the recommended limit (200 mg/l).Please purchase PDFcamp Printer on http://www.verypdf.com/ to remove this watermark.Moreover, water turbidity of the samples from the well (5.15 mg/l) wassignificantly (P<0.05) higher than the recommended level. All the testedlegume seeds were rich in K (0.97-2.1g/100g), P (0.083- 0.65 g/100g)and Ca (0.1 – 0.18 g/100g), while they contained low amounts of Co(0.005 -0.06 mg/100g). Seeds of faba bean followed by white bean weresignificantly (P<0.05) higher in Zn than the seeds of other legumes,Chickpea seeds contained significantly (P<0.05) the highest amount ofMn. Faba bean, pigeon pea and chickpea were significantly (P<0.05) therichest in Fe. Selenium was found to be deficient in both water samplesand legume seeds. Furthermore, the level of phytic acid wassignificantly (P<0.05) the lowest in chickpea (0.017 g/100g), whilelablab bean had the highest concentration (0.14 g/100g), this perhapsincrease the chelate effect on minerals availability particularlyphosphorus.
