An irrigation experiment with sweet sorghum was carried out in La Rinconada (Sevilla), as a part of a series of experiments being performed in Andalucia to study the possibilities of this promising crop in the area. 2 different regimes of water application, normal and restrictive during the season of maximum growth were assayed. 2 different dates to stop irrigation, September 1st., and October 1st., were considered in each treatment. The amount of water applied ranged between 749,5 mm and 1.064,5 m. Three varieties, "Dale", "Keller" and "Wray" were used. The standard regime of irrigation was clearly better than the restrictive one, however, no significant difference could be found between the 2 dates in which irrigation was no longer applied. (Each treatment, or combination of treatments, was harvested in different date, according with its maturity). "Keller" variety was better, specially when dry matter was considered. The best results, 10,29 t/ha of sugars (juice and bagasse) and 18,19 t/ha of dry fiber, were obtained by irrigating the "Keller" variety with 864,9 mm of water until September 1st.
