Integrated fertilization strategies to improve agronomic parameters of common bean

Resumen

Objective: To investigate the effect of biofertilizers and phosphorus rates on overall growth, biomass production, chlorophyll content and yield of common bean Azufrado Reyna under field conditions.

Design/methodology/approach: Split plot in a randomized complete block design with four replicates and four treatments (three phosphorus rates and the control). Growth index, growth components, aboveground biomass and yield were evaluated.

Results: The phosphorus rates influenced the growth index, growth components, aboveground biomass and yield with respect to the control; while the combination of biofertilizers positively interact with some of the parameters evaluated.

Limitations on study/implications: The study only assessed the evaluation of agronomic parameters; therefore, it is convenient to quantify the performance of biofertilizers in contrasting soil conditions.

Findings/conclusions: The aplication of biofertilizers with lower phosphorus rates had a positive effect on grain yield, thus reducing the amount of chemical fertilizers. Also, the dry weight of grains showed the highest correlation with grain yield.
