Influencia de la fertilización foliar sobre el comportamiento agronómico y rendimiento del cultivo de maíz (Zea mays L.).

VIII. SUMARY The objective of the present experimental work was to define the influence of foliar fertilization on the agronomic behavior and performance in the cultivation of maize, through the implementation of 5 Biostimulants with 2 dosage levels in the area of Ricaurte. The Biostimulants employees are: Bombardier, Bioalgax, Humisolve 14 ION, Aminoalga and Evergreen; the planting material was the 7088 Dekalb maize hybrid. The experimental work was carried out in the grounds of the Finca "La Otilia", located in the enclosure Las Cañitas, Parish Ricaurte, Canton Urdaneta, Province of Los Ríos, whose geographical coordinates are longitude 679 581 UTM, latitude 9819 985 UTM and altitude of 38 Masl. The treatments were arranged in a randomized complete block random design with three replications. To determine differences between treatments, we used the multiple range test Tukey to 1 % of significance; by which it was determined that the Biostimulants presented statistical differences in the variables width of cob and weight of 1000 seeds. The Biostimulants showed no significant effect on the performance of the hybrid. The biostimulant Bombardier in doses of 2 L/has been applied to the 20 and 35 days after sowing reached the higher yields of maize hybrid of 10 843.20 kg/ha, respectively, and According to the economic analysis report the highest profitability with a utility of $ 3 091.67 with a benefit-cost ratio of $3,92. Witness obtained the lower yield of 6 385,82 with a utility of $1 408,63. Keywords: Influence, foliar fertilization, performance, corn.
