Substitution of chemical fertilizers with biofertilizers is a key component of sustainable agricultural plans in crop production. This field experiment has been conducted during two successive seasons 2018/2019 and 2019/2020 to examine the effect of substitution of mineral NPK fertilizers with biostimulant (yeast and/or moringa extract). Three fertilization treatments have been conducted in this experiment in factorial design. Yeast, moringa extract and their combination have been used compared to control (100% NPK). Treatment with 100% NPK significantly increased growth and yield components of chia plants. Plant height, number of branches, leaf area, spike height, number of spikes, fresh and dry spike weight, seed yield, leaf greenness, and protein content gave highest values under 100% NPK dose, and decreased with biostimulant treatments; yeast and/or moringa extract. In contrast, treatment with yeast and/or moringa extract significantly increased the quality components of chia. Treatment with yeast and/or moringa gave the highest fatty acid content. It is concluded that completely substitution of mineral fertilizer with biostimulants had negative impact on growth and yield components. In contract, the quality significantly improved under biostimulant treatments. The results of this study suggest that partial substitution of mineral fertilization with yeast and/or moringa extract may maintain high yield with high quality
