Crop biostimulation is increasingly emerging as a necessary complement for plant stress management and yield optimization in integrated and sustainable agriculture programs. Likewise, the use of remote sensing as a diagnostic and decision-making tool in olive groves has also been established within the framework of precision agriculture.
One of the limitations that have been presented in the cultivation of coffee in the Central American region have been climatic variables, in which high temperatures, together with ultraviolet light levels, as well as rainfall and its intensity, have caused serious problems for the development of the crop. There are physiological imbalances that cause losses in stimulation and flower setting, reaching losses of more than 60% depending on the variety. The objective of this work was to evaluate...
The flowering and fruit set is one of the most sensitive and critical phenological stages for the productive development of the crop, especially if some stress factor is involved that can unbalance the plant and negatively affect fruit set. The state of health and nutritional balance of the plant will also determine the capacity of retention of fruits that the vegetable will be able to develop later. Organic biostimulants, such as amino acids or algae extracts, have been used for years preci...
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...
