Comportamiento agronómico y aporte nutricional de maíz híbrido y criollo para ensilaje con aplicación de bacterias acidolácticas en el trópico húmedo.

Abstract

A research project was carried out on the grounds of the Río Suma experimental farm of the agricultural engineering career of the Laica Eloy Alfaro University of Manabí, located in El Carmen Manabí canton at kilometer 30 of Santo Domingo Chone road, with the objective of evaluating the agronomic behavior and nutritional contribution of hybrid and creole corn for silage with the application of lactic acid bacteria in the humid tropics, for this silos were prepared with covers of 1 cubic m in which they were supplied with 6 ml of the Silobacter® plus molasses; the corn plants were planted at a distance of 20 cm by 70 cm in the hybrid variety, while in the creole it was grown at 20 cm by 80 cm; 80 days after sowing, the plants were cut and the threads were made, which were opened after 40 days; a completely randomized block design (DBCA) was established with the 2 varieties as treatments and 7 repetitions, a 5% Tukey test was performed to compare the means. In the results obtained on the agronomic performance, it was determined that the Creole corn reached the highest production in green matter with 48,999.31 kg per hectare and a percentage of dry matter of 24.59%; Regarding the bromatological analysis, it was determined that the hybrid corn variety had the best percentages in crude protein with 11.19% in ether extract with 4.51% and ash with 8.42%.
