Abstract

The results of a study on registered seed of sugar cane developed in areas of the Basic Seed Bank of the province of Cienfuegos (BSB) and in the Registered Seed Bank (BSR) of the Antonio Sánchez Agroindustrial sugar company, in the province of Cienfuegos are presented. Plant cane strain, the cultivar used was in BSB C86-12 and in BSR Co997. The trial was fertilized at the time of planting with cachaça, doses, 30 tons ha^-1 and Potassium Chloride at 90 and 60kg ha^-1, in accordance with the recommendations of the Fertilizers and Amendments Recommendations Service (SERFE) for this carrier by type of soil, additionally two bio-stimulants and their combinations were used. The randomized block design was used with five treatments and five repetitions in 64m2 plots. The variables evaluated were cane t ha^-1, total number of roots, juice quality expressed as percentage of cane pol (PPC) and reducing sugars and economic valuation. Simple classification variance analyzes were performed for the first three variables studied, as well as Tukey’s multiple range test p<0.05 whenever there were significant differences between treatments, in addition a regression analysis was performed between the total roots per treatment. and cane production. As effects, it was obtained that the application of the bio-stimulant FITOMÁSPLUS at a total dose of 2 liters ha^-1 and 5.2 milliliters of underplant ha^-1 with one and two applications achieved the best results in cane production and the number of total roots. It was also observed that the number of total roots had a positive and significant relationship with agricultural yield, which may be one of the possible causes of the increase in agricultural production and in the variables of the quality of the juice under study there were no differences, between the treatments, in addition the economic valuation demonstrated a positive benefit/cost relationship.
