Eficacia de enmiendas y aminoácidos sobre el crecimiento de plántulas de soya (Glycine max) en suelo de tendencia salina

The objective of the research was to evaluate the efficacy of amendments and amino acids on the growth of soybean seedlings (Glycine max L) in saline-prone soil. The experiment was carried out under shady conditions at the ESPAM MFL polytechnic campus. Two trials separated in time were developed. In the first, three doses of agricultural gypsum - YA (14, 28 and 42 g per pot) and three doses of compost - CP (14, 28 and 42 g per pot) were evaluated. The second trials, three sources of amino acids (vegetable, marine and animal origin) were evaluated. As an amendment, the best combination of YA + CP obtained in the first experiment was used. In experiments, root and plant dry mass and leaf area were recorded. The data obtained were analyzed through ANOVA, orthogonal contrast and the separation of means was carried out with the Tukey test (α = 0.05). No significant differences (p>0.05) were found for the YA x CP interaction, nor for the YA and CP doses in a simple way. The orthogonal contrast between the averages of YA+CP vs. The control, did show significant differences (p<0.05), so it is concluded that the minimum doses of YA and CP are sufficient to enhance the growth of soybean seedlings in soil of saline trend. For the second experiment, significant differences (p<0.05) were found between the amino acid sources, where the amino acid of plant origin was the one that reached the highest values in all the growth variables evaluated
