Aplicación combinada de quitosano y HMA en el rendimiento de maíz

Abstract

Two experiments were carried out in field conditions, with the objective of evaluating the QuitoMax ® and EcoMic ® biostimulants, alone and in combination, in the yield of two varieties of corn ( Zea mays L.), during the years 2015 and 2016. In both Experiments, the biostimulants were applied by imbibition of grains in QuitoMax ® solutions, which were then pelletized with EcoMic ® , prior to sowing and, subsequently, the plants were sprinkled in the leaf area with QuitoMax ® . In the first experiment, the different combinations of the bioproducts stimulated the majority of the yield components of corn, Creole variety. In the second, the treatment of the grains with QuitoMax ® and EcoMic ® stimulated the diameter of the ear, the number of rows of grains and the agricultural yield of the P 7928 variety, together with the foliar sprinkling of QuitoMax ® in the crop. In the Creole variety, the treatment of the grains prior to sowing with QuitoMax ® and EcoMic ® followed by the foliar spray of QuitoMax ® , increased the yield with respect to the pelletized control with EcoMic ® by 62 %, while in the P 7928 variety, both the treatments of each product alone and their combinations, increased the yield with respect to the untreated control between 15 and 22 %. In general, corn yield increased significantly with the use of biostimulants, which suggests that application in the field of EcoMic ® and QuitoMax ® , alone and in combination, is a recommended option to increase crop yields, depending on variety.
