CHAVEZ REA, Melanie Arline  and  VASQUEZ-GUZMAN, José Eliécer. Efecto de la aplicación de tres dosis de Bacillus subtilis en tres variedades de fréjol arbustivo. Siembra [online]. 2021, vol.8, n.2, e2657. ISSN 2477-8850.  https://doi.org/10.29166/siembra.v8i2.2657.

The objective of this research was to evaluate the effect of applying three dosages of Bacillus subtilis to three varieties of beans (Phaseolus vulgaris L.) to determine an increase in yield and in other traits. Three dosages were applied, D1 without apliction (check), D2 250 ml and D3 500 ml, of biological inoculant NITO (Bacillus subtilis), dissolved in 200 L of water to Paragachi, Campeón and Centenario varieties. The trial was sat up in the Campo Académico Docente Experimental La Tola, using an split plot arrangement in a experimental Randomized complete block design, with three replications. The following traits were evaluated: days to harvest, pods per plant-1, beans per pod-1, weight of 100 seeds, and yield in kg per ha-1. The highest yield got the interaction 500 ml dose x Centenario variety with a seed yield of 3763.89 kg ha-1 providing an economic profitability of 1.32 dollars. Likewise, differences were observed in concentration of available phosphorus due to the Bacillus subtilis, with dosage 3 providing the highest concentration of phosphorus with 351.97 ppm.

Keywords : seed yield; phosphorus; plant pathogens; roots.
