Implication of Planting Media / Initial Soil Nutrient to the Quality Parameters of Flour Produced from Some Selected Yam Varieties for Processing and Export

To combat insufficient space for planting food, insecurity and to ensure the availability of adequate food nutrients crops are grown in different media. In this study, three yam varieties: Dioscorea alata, Dioscorea rotundata, and Dioscorea cayennesis were sourced from a local market in Ebonyi State and divided into two portions. One portion was processed into flour and was evaluated the second portion of the yam was planted in two different planting media: soil and bag and their nutrient composition was assessed. The result generated the mineral composition of Mg, P, K of the yam samples were better improved and retained when planted in direct soil than in bags, except DR in which the P content was better retained in DRB than DRS. The mineral composition of calculi is retained better when planted in bags than in direct soil except in DR.
