Jaffa orange
The Zionists who immigrated to Palestine introduced the advanced cultivation methods that spurred the 'Jaffa' orange industry. According to the Hope Simpson Enquiry of 1930,"The cultivation of the orange, introduced by the Arabs before the [beginning] of Jewish settlement, has developed [a lot]  [as a] consequence of that settlement. There is no doubt that the pitch of perfection to which the technique of plantation and cultivation of the orange and grapefruit have been brought in Palestine is due to the scientific methods of the Jewish agriculturist."
