Effect of Higher Density Planting on Irrigation Water Use and Yield of Sugarcane
Author: Khodadadi Dehkordi, D.
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.
