Ibn Bassal the Pioneer of Research in Experimental Agronomy in the Arab Islamic Culture

This research work rates among those studies, which deal with agronomy as one type of the scientific aspects of the Islamic Arab Legacy. In the period between the 4th and the 6th centuries of the Hijri calendar, Andalusia witnessed the emergence of an agricultural school, whose leaders‘ concerns focused on studying plants from an agronomist perspective. They held meetings and had their own deliberations, and wrote books in this field. The Andalusite Al Haj Abu Abdallah Moh‘d Ibn Ibraheem Ibn Bassal was a pioneer of that school. He successfully used the scientific experimental method in conducting his research, and eventually obtained substantial conclusions, which he embodied in a book, that was clearly outstanding among all other volumes available in Andalusia, East and West. His contemporary authors, and those who came after him as well, described it as the book that is completely based on its authors personal experience. Indeed, the book reflects the practically proven hands, on the one hand, and the applicable ones on the other. The book is exclusive, too; it is free of quotations from any other source. The author did not mention any title of any reference he had acquainted himself with. as he was quite aware that he was only writing hard scientific facts, which, hence, need no reference. Finally, its actually a book that is rich with knowledge and information related to tree planting, pruning and texture improving, and with issues dealing with land, water and fertilizers.
