Abstract
Recently, there is a great demand for bio-fertilizer usage, to reduce the detrimental effects of late sowing and enhance crop cultivation. Thus, the current research aims to improve wheat plant (Gemiza-11 and Sids-13 cultivars) growth, some physiological parameters, grain yield and quality by the use of yeast extract as foliar treatment. Therefore, throughout the course of two consecutive winter seasons, the effects of foliar treating yeast extract (1%, 2% and 3%) at two different sowing times (15th of November and December) on growth, certain biochemical characteristic sand yield attributes were assessed. The obtained results demonstrate the superiority of Gemiza-11 cultivar over Sids-13 cultivar in terms of growth, yield quantity, and quality. Furthermore, compared to plants sown on15th November, the late sowing date Foliar treatment with yeast extract greatly enhanced growth characteristics, photosynthetic pigments, indole acetic acid, some osmoprotectants, yield, and its constituents in wheat plants. Finally, the above findings implied that exogenous yeast extract enhanced photosynthetic pigments, indole acetic acid (IAA), and the studied osmolytes and phenolics which further promoted growth and productivity of the two tested wheat cultivars under late sowing date. Therefore, the stimulative effect of yeast extract may be suggested as an effective strategy for strengthening the late sowing (15th December) stress tolerance of wheat plants.
