Influencia de la fertilización sobre la incidencia de Empoasca kraemeri Ross y Moore en dos tipos de suelos y grado de afectación sobre Phaseolus vulgaris L.

The study of the fertilization about the incidence of the leaf hope (Empoasca kraemeri Ross and Moore) of common bean (Phaseolus vulgaris L.) in Villa Clara had as aspects of interest different fertilization variants and her influence on yield components. For their quantification take sample on parcels with different treatments. The variety Bat-482 was used in two types of soils to determine the answer before the fertilization with Rhizobium, Micorrizas, Compost and Urea. Later on the number of sheaths and grains were averaged by plant to determine the grade of affectation for E. kraemeri about the different varieties. The fertilization with Micorrizas and Compost caused a smaller incidence in comparison with the Urea in both soils. The maximum yields were reached in the varieties of black test note with an average of 9.32 sheaths for plant with a grade of affectation of 3. Velasco Largo and Bat-482 with 3.47 and 2.62 sheaths for plant respectively showed bigger susceptibility with a grade of affectation of 9. [ABSTRACT FROM AUTHOR]
