| Abstract | ||
| This study was conducted over two consecutive growing seasons of 2022/2023 and 2023/2024 to investigate the effects of humic acid (HA) and some biofertilizers on chia plants with respect to vegetative growth characteristics, seeds/yield, fixed oil content and chemical composition. Concerning this, two factors were examined the first factor (A) was HA at 3, 6 and 9 ml/L, while the second factor (B) was biofertilizers effective microorganisms (EM) or Minia azotein (MA). Highest main branch number/plant, herb dry weight, seed yield, fixed oil percentage and yield as well as,, photosynthetic pigments were significantly promoted by fertilizing chia plants with HA compared with control treatment. The best values for all previous characters were obtained from the high level of HA. Also, the same results were obtained with the treatments of EM or MA at different concentrations however, the best treatment was EM at 50% or MA at 25%. The best interaction treatment for the highest yield of chia plants was recorded with the HA at 9 ml/L combined with EM at 50% or MA at 25%. | ||
