Effect of tuber cutiing, phosphorus levels and micro-elements on jerusolem artichoke yield and quality under drip-irrigation on sandy soil [electronic resource].

Includes references.

Jerusalem artichoke is one of the comparatively new and non-traditional vegetable crop intrOduced in the Egyptian agriculture. In a field experiment, two cultivars of Jerusalem artichoke (Helianthus tuberosus L.,)i.e., cv. Local and cv. Fuseau were subjected to different supplies of phosphorus levels (7.5, 15 and 22.5 Kg P₂O₅ / Fed) with or without microelements (Zn, Fe, and Mn) and two planting materials i.e. whole seed tuber and cut· tubers under drip-irrigated sandy soil during 2005 and 2006 seasons. Results indicated that' Ftiseau and Local cultivars growth parameters responded positively with whole seed tuber in the two seasons. Fuseau cultivar had higher stem length, No. of branches, fresh weight of branches/plant, leaf chlorophyll content, tuber fresh weight plant per total yield and dry matter percentage. Meanwhile, the Local cultivar had higher No. of main stems.
