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.
