The aim of this research was to find out if there were any differences in nutrient composition of Citrullus vulgaries (water melon) during storage period after plucking were studied. The moisture content from Zaria and Kaduna (Central Market) was found to be 94.6 and 94.2%, respectively while that from Jaji was 93.4% due to the period of storage. The ash content from Kaduna and Zaria were 0.55 and 0.50, respectively while that from Jaji was 0.50. The dry powder of the whole water melon was fairly rich in lipids (Jaji 0.15%, Zaria 0.10% and Central Market 0.10%) while an acceptable amount of protein was found (Jaji 0.50, Zaria 0.50 and Central market 0.60). Mg, Ca, and Fe were also found in the samples. The result of this work suggest that water melon fruit that cannot be consumed within the shelf life period can be dried, ground into powder and used as animal feed supplement instead of leaving to spoil.
