DESCRIPTION
The present study has been conducted in the framework of the Italy - Lybia bilateral cooperation project "Improvement and Valorisation of Date Palm in Al Jufrah Oasis", funded by Iatlian Cooperation and carried out by Istituto Agronomico per l'Oltremare (Italy) in collaboration with the Libyan Ministry of Agriculture. In this framework, the characterisation and description of local varieties, performed through the sampling and description of genetic, morphometric and chemical characteristics, is accompanied by an integrated study of the palm dates cropping system in the Al Jufrah Region. Such study has been carried out by means of the set up of Geographical Information System of Date plantations for the five oasis of Waddan, Hun, Sokna, Zellah and Al Fugha.

Passport
Origin and distribution: common variety of Waddan,
Sokna and Hun. It’s one of the most widespread variety
in Al Fugha and Zellah
Productive area in Al Jufrah Oasis: 3 %
Mean Production in Al Jufrah Oasis: 65 Kg/tree
Agronomic characteristics: rapid growth of the plant
with quick ageing process. High productivity, sensitive
to pests and water salinity, good rooting capacity in bad
soil situation. Good offshoot capacity, with high
percentage of offshoot developing during plantation
Flowering period: February - March
Commercial maturity stage: Tamar
Harvest period: in October by removing of bunches
Fruit and trade characteristics: with a low sugar
content, this is the date variety most recommended for
diabetes sufferers. Good for postharvest processing and
other uses for animal feed
