Abstract

In order to investigate the growth reaction, yield and quality of sunflower and guar in mixed crops under the influence of mycorrhizal inoculation, an experiment was conducted in a research farm of Agricultural Sciences and Natural Resources University of Khuzestan in the winter of 2019 in a factorial based on a randomized complete block design with Four repetitions were performed. The experiment consisted of two levels of mycorrhiza (inoculation and non-inoculation) and five planting ratios including (100% sunflower), (100% guar), (75% sunflower + 25% guar), (25% sunflower + 75% guar) and (50% sunflower + 50% guar). The results showed that dry matter yield in guar and sunflower was affected by a significant planting ratio, so that the highest dry matter yield of guar and sunflower was from 100% guar treatments with an average of 827/23 kg / ha and 2617/9 kg / ha treatment of 75% sunflower + 25% guar gum. Plant height in sunflower and guar had a significant effect on planting ratio, so that the highest plant height in sunflower and guar was from 75% sunflower + 25% guar, with a mean 116/96 cm, and 100% guar With an average of26/38 cm.
