During the past two decades the presence of amino acid based biostimulants in the market has shown a steep growth. Many products have become available but, for many of them, a through analytical characterization of their composition has remained elusive.
The following article shows the results of an exhaustive comparative study of both analytical characterization and agronomic efficacy of four biostimulant products based on amino acids from different sources of raw material (animal and plant origin) and methods of obtaining (chemical hydrolysis or enzymatic). Regarding the analytical characterization, the results show a greater degree of hydrolysis (greater amount of free amino acids) and a more complete and balanced amino acid profile of th...
Post-emergence herbicides are commonly used to control weeds in field crops worldwide Depending on their crop selectivity, herbicides may cause crop adverse effects particularly under stress conditions, such as reduction of chlorophyll content, affection in photosynthesis performance and appearance of micronutrient deficiencies On the other hand, the application of amino acid based biostimulants have beneficial effects on crops reducing production losses caused by environmental stresses Howe...
Biostimulants offer a novel approach for the regulation of crucial physiological processes in plants. Recently, it has been observed that the application of biostimulants on both seeds and plants may ameliorate to some extent the negative effects of abiotic stresses such as drought, heat, salinity, and others. In the climate conditions of Bulgaria, the early developmental stages of warm climate crops, like maize, often occur under suboptimal temperatures. Although the mitigation of abiotic s...
In order to characterize the effect of the INICIUM® product, the aerial and underground development of pepper plants treated and untreated with the root application biostimulant was monitored. The results showed an incentive effect of growth in the post-transplant phase in plants treated with INICIUM®, which is visualized in an early growth of the root system. This effect seems to be associated with the production of thinner and longer roots that would provide a greater surface area of wat...
