Effect of higher density planting on irrigation water use and Yield of Sugarcane

Sugarcane is one of the important crops that needs plentiful water in tropical and semi-tropical regions. this crop is widely grown in khuzestan province of iran. in this study,triple-row planting of sugarcane was evaluated and compared to double-row planting as currently being practiced in the region. results showed that in spite of the higher density planting in triple-row planting,there was no significant difference between triple-row planting and double-row planting in terms of leaf sheath moisture,leaf nitrogen,ridge ec,qualitative situations of cultivar,plant height and stem diameter. however,the number of shoots and stems per m2 in the triple-row planting were found to be higher than in the double-row planting and the difference between them was significant at 5% level. in addition,water application efficiency,water use efficiency (wue),mean yield of sugarcane and sugar content in triple-row planting were higher than double-row planting. © universiti putra malaysia press.
