studies on the Proximate Chemical Composition, and Mineral Element Contents of Five New Lowland Rice Varieties Planted in Ebonyi State

摘要

We investigated the proximate chemical compositions and mineral element contents of five new lowland rice varieties viz: IR77384-12-17-3-18-2-B, IR68, PSBRcSO, IR77647-3B-8-2-2-14-4 and IR75395-2B-1-1-2.4 with a view to recommending them to farmers and consumers in Ebonyi state and its environs.. After the analysis, data were collected for percentage proximate composition (moisture, crude protein, fat, crude fiber, ash and carbohydrate) and mineral element contents (nitrogen, phosphorus, potassium, calcium, magnesium and sodium). The results were obtained as mean and standard deviation of the values expressed in percentage as follows; 11.5~ ± 9.8 moisture 25 ± 0.8 fat, 5.8 ± 1.2 crude protein, 1.6 ± 0.3 crude fiber, ( ± 0.2 ash, 78.0 ± 13.2 carbohydrate, 09± 0.04 nitrogen, 0.11±0.05 calcium, 0.21±0.002 potassium, 0.13 ± 0.00 sodium, 0.53 ± 0.03 phosphorus and 0.17 ± 0.02 magnesium.Based on the percentages of the various chemical components of these five rice varieties, we therefore persuade farmers and consumers in Ebonyi state and its environs to accept these rice varieties.
