Where the effect of the application of seven bioles in three propagative methods was studied; using (DBCA) with arrangement of divided plots resulting in 21 treatments; including a witness, it was worked with three repetitions. Phenological, physiological, health and productive variables were evaluated; and the cost-benefit ratio of each of the treatments was established. Tukey (P≤0.05) was used for the statistical analysis of the means. Based on the variables studied, it was concluded; that in sprouting the highest average was presented by T13 (b4a0); with a moderate sprouting. In flowering and fruiting, the highest value was obtained by T14 (b4a1) obtaining 100%. The highest plant height was presented by T3 (b0a2) with a height of 3.80m. The highest value in stem diameter was presented by T15 (b4 a2) with 12.05 cm; This treatment obtained a good leaf color and strong vigor. In the incidence of witch's broom, T12 (b3a2) was less affected due to its high potassium content; In cherelle wilt there was no statistical significance; however, a notable reduction was observed. After 120 days of application of the bioles the number of diseased ears (NME) decreased the treatments, presented averages lower than 1.33 (NME). Regarding the productive variables, the highest average was obtained by T14 (b4 a1) with an average of 30.17 healthy ears. This treatment also obtained the highest yield with a value of 2790.67 kg / ha / year. In soil analyzes, an increase in macro and micronutrients was found, as well as a noticeable reduction in heavy metals. In the B / C ratio, T14 (b4 a1) stood out with a B / C of USD 4.11. Keywords: Soil, biol, heavy metals. |
