Title: Evaluation of irrigation in triple-cropping of sugarcane
Jamal Saudi is currently a PhD student in Soil Fertility & Chemistry from Islamic Azad University (IAU), Khuzesta n Science & Research Branch. He has completed his MSc in Agriculture Engineering from Islamic Azad University, Khuzestan Science & Resear ch Branch, in 2011 and he has graduated in Agrology from Shahid Chamran University of Ahvaz in 1992. He is presently the Director of Applied Research at Dehkhoda Sugarcane Agro-Industry Co, in Iran. In the course of more than 25 years h e became experienced with many aspects of sugarcane researches an d cultivations.
Sugarcane is one of the important plants in tropical and semi-tropical regions that need plentiful water, these plants cultivates in extended area in Khu zestan province of Iran. In this study, triple-cropping of sugarcane cultivar Cp69-1062 on the ridge was evaluated and compared to double-cropping of sugarca ne cultivar Cp69-1062 on the ridge that is current planting region. Results showed that in spite of higher dense plan ting in triple-cropping, in leaf sheath moisture, leaf nitrogen, ridge EC, qualitative situation of cultivar, plant heig ht, stem diameter and number of shoots, there was not any significant difference between triple-cropping with double-cropping of sugarcane on the ridge. However, the differenc e between numbers of stem per m² in triple-cro pping with double-cropping of s ugarcane was significant at 5% level. Also, water use efficiency (WUE) and the mean y ield of sugarcane and sugar in triple-cropping were more than double-cropping of sugarcane.
