Different aspects of non-standard foliar fertilizers based on amino acids, phytohormones and plant extracts

Abstract

We studied different aspects of application of foliar non-standard fertilizers based on amino acids, phytohormones and plant extracts. The trials were carried out at the level of the seedlings, individual plants grown in semi-controled conditions and plants grown in the field. Various energetic and thermodynamic parameters were analyzed, then the chemical composition (mineral elements, different sugars, secondary metabolites, etc.), as well as parameters of plant growth and their yield, in order to better assess the impact of these fertilizers on crops. We found that on maize seedlings it works by changing the content of various elements, then the polyphenol profiles, as well as thermodynamic parameters, where this effect does not only depend on the dosage of the fertilizers, but also on the corn genotype. We also found that the fertilizers affect the energetic and thermodynamic parameters of individual maize plants, as well as the parameters of plant growth. The most significant and most diverse results were obtained by analyzing the yield and components of the yield of many different crops (crop, fruit, vegetable), as well as their chemical composition (mineral elements, different sugars, secondary metabolites, etc.) in terms of improving nutritive quality. It was noticed that these fertilizers greatly affect the content of microelements, starch and crude proteins in maize and barley, sugar and polyphenol content in various fruit trees, as well as in soybeans, in which we note that in certain agroecological situations these fertilizers have led to spectacular magnification yields of different crops, but there were also situations when they did not have any positive effect on crop yields. Overall, the early treatment of cultivated plants with non-standard fertilizers greatly affects the vigor of seedlings of these plants, which is of great importance for crop yield. These fertilizers also significantly affect the quality of crop yield in terms of improved chemical composition of edible parts of these plants.
