In order to evaluate water productivity, brix percentage, internode diameter, root dry weight, sugarcane stem height, and chlorophyll content of legume leaves in intercropping of sugarcane with legume plants, an experiment has been conducted in a randomized complete block design with 14 treatments and four replications during 2016-17 at two locations in Ahwaz. The treatments include sole sugarcane, sole soybean, sole cowpea, sole soybean + rhizobium, sole cowpea + rhizobium, sole sugarcane + mycorrhizal, intercropping sugarcane with cowpea, intercropping sugarcane with soybean, intercropping sugarcane with cowpea + rhizobium, intercropping sugarcane with soybean + rhizobium, intercropping sugarcane + mycorrhizal and cowpea, intercropping sugarcane + mycorrhizal and soybean, intercropping sugarcane + mycorrhizal and soybean + rhizobium, and intercropping sugarcane + mycorrhizal and cowpea + rhizobium. Results show that the highest water productivity (4.46 k/m3), the highest sugarcane stem height (215.6 cm), the largest internode diameter in the middle (42 mm) and at the bottom (46.06 mm) of the stem, the highest dry weight roots (187.8 g), and the highest brix percentage (21.88%) of sugarcane stem extract have belonged to intercropped sugarcane + mycorrhizal and cowpea+ rhizobium treatment, which is 31.61%, 16.14%, 32.42%, 28.35%, 8.89%, and 8.31% higher than sole sugarcane. Mycorrhizal symbiosis has been positive in sugarcane, and when mycorrhizal fungi and cowpea are present simultaneously in a treatment, their synergistic effect on the evaluated traits is positive, too.
