Efecto del silicio y bioestimulantes sobre el rendimiento del cultivo de maíz (zea mays l) amarillo duro

The present investigation had as objective to evaluate the efficacy of combined applications of Silicon and biostimulants on the yield of hard yellow corn. Therefore, 3 types of biostimulants (algae extract, phytohormones, humic acid) were evaluated in interaction with different doses of silicon (5 mL L-1 (1 L ha-1), 10 mL L-1 (2 L ha-1), 15 mL L-1 (3 L ha-1)) as well as an absolute witness and a silicon witness. A completely randomized block design (DBCA) was used with two factors in the AxB + 2 study with 9 treatments, 3 replicates and a total of 33 experimental units. The main variables to be evaluated were the following: plant height (m), Number of rows of grain / corn, Number of grains per row, grain weight per corn, corn length (cm), corn diameter (cm), corn weight in kg, and corn yield. The data were subjected to analysis of variance and the separation of means with the Tukey test at 5% probability of error. The results in this investigation determined that the yield of hard yellow corn was not significantly influenced (p> 0.05) by the evaluated treatments. The orthogonal contrast analysis performed between treatments vs. the control was statistically significant (p <0.05). On the other hand, the orthogonal contrast performed between biostimulants vs. silicon did not show significant statistical differences (p> 0.05), which indicates that both silicon and the other biostimulants can be used in isolation and would produce the same effects on performance.
