  • 1. NUTRITIONAL PROFILEOF SHEA FRUIT PULPFROM NIGERIAF.D UGESEI, K. P. BAIYERI2 & B.N.MBAH21 Department of Crop Production, University of Agriculture, Makurdi,Nigeria2 Department of Crop Science, University of Nigeria, Nsukka, Nigeria.
  • 2. INTRODUCTIONThe shea tree occurs abundantlyacross Nigeria’s savanna zoneMajor zones are the southern guinea-,northern guinea- and the sudansavannaDifferent parts of the tree are usefulFruit pulp is edible and ripens at avery critical time of the year
  • 3. PROBLEM STATEMENTNutritional content of fruit pulpnot adequately exploredPossible relationships amongnutritional traits unknownThe above could underminedomestication efforts
  • 4. OBJECTIVESDetermine proximate traits ofNigerian shea fruit pulpAscertain elemental nutrientcomposition of the fruit pulpObserve possible relationshipsamong nutritional parameters
  • 5. MATERIALS AND METHODSFruit pulps collected across 7 locationsin 3 agroecological zonesLocations: Lokoja, Makurdi, Akwanga,Kachia, Jalingo, Yola, Kano15-25 trees were sampled in each zoneMilled oven dry samples subjected tolaboratory analyses using standardmethods
  • 6. STATISTICAL ANALYSISAnalysis of variance (ANOVA)F-LSD where applicableCorrelation analysis
