Abstract
Background and Objective: The study was conducted in order to investigate the effect of ecological inputs on some quantitative and qualitative characteristics of Borago officinalis.
Materials and Methods: The experiment was used in a completely randomized block design with three replications in 2018-2019 in Fahlian, Noorabad, Fars province. The first factor includes compost at three levels (0, 5 and 10 ton.ha-1) and the second factor includes biological fertilizers at four levels (Control, Mycorrhizal, Bacillus and Mycorrhiza + Bacillus).
Results: The results showed a significant increase in the chlorophyll index and mucilage of borage leaf with increasing compost levels from 0 to 10 tons per hectare, and among the biofertilizer levels, the highest amount of these characteristics was obtained from the combined treatment of mycorrhizae and bacteria biofertilizers. The highest amount of studied morphological and functional characteristics, especially the number of flowers per branch, the number of flowers per plant and flower yield was obtained when applying 10 ton.ha-1 of compost and integrated application of the studied micro organisms, and the lowest amount was obtained from control, which had no compost and biological fertilizers were not used.
Conclusion: The application of compost and biological fertilizers studied (mycorrhizae and Bacillus) had a positive effect on quantitative and qualitative characteristics of borage. Although each of these nutritional sources in the production of borage led to the improvement of studied characteristics, nevertheless, the combined use of compost and biological fertilizers had a greater effect and efficiency in increasing these traits.
