Evaluation of the potential of mycorrhizal fungi and RHIZOBIUM bacteria in the phenological development and yield of the bean (PHASEOLUS VULGARIS) crop

Abstract

The study was carried out at the National Center of Reference in Agroplaticultura (CNRA) of the UNAN-León Agricultural Campus. Beans (Phaseolus vulgaris) have historically been cultivated based on the basic diet of Nicaraguans. . The objective of this research was to evaluate the availability of nutrients in soils inoculated with Mycorrizas and Rhizobium, analyzing their effect on the vegetative development and yields of the bean (Phaseolus vulgaris) crop. The design used was a BCA in which three blocks were established, randomly distributed in the study area, this was divided into 4 treatments (T1: Mycorrizas, T2: Rhizobium, T3 Mycorrizas + Rhizobium and T4: Control) with 3 repetitions for a total of 12 experimental units, each experimental unit was 3m long by 3m wide with a separation between each subplot of 0.50cm. An Analysis of Variance (ANOVA) was performed using the statistical program SPSS with 95% confidence and making a comparison of means with Tukey. The results showed that there was a significant difference between the treatments, where T3 obtained the highest average height, diameter, number of leaves, number of pods, grains per plant, spore count and production with 1,798 Kg/Ha. It is concluded that the variables are influenced by the inoculum with Mycorrizas and Rhizobium, registering the highest averages and the highest yield in the treatment: Mycorrizas + Rhizobium.
