VASQUEZ, Santiago C et al. EFFECT OF PLANT DENSITY ON YIELD COMPONENTS OF COMMON BEAN GROWN UNDER INTER-ANDEAN MOUNTAIN CONDITIONS OF ECUADOR. La Granja [online]. 2024, vol.39, n.1, pp.160-170. ISSN 1390-8596. https://doi.org/10.17163/lgr.n39.2024.10.
Common bean is an important crop due to its high nutritional value. However, its production in Ecuador has decreased due to biotic and abiotic factors. Understanding the mechanisms that determine the yield components of this crop is essential to establish strategies that allow increasing the yield. In this study, the plant density was modified to evaluate its impact on yield and its two main components, the grain number and grain weight under field conditions in an Andean region of Ecuador. Two experiments planted on different dates were performed, where two planting densities 4 and 11 plants m−2 were evaluated. The effect of the treatments was studied on the length of the period, from emergence to anthesis, the number of full and empty pods, grain number, 100 grain weight and grain yield. The results indicate that the plant density has a significant effect (p<0.05) on the yield, reaching an average of 257.15 g m−2 in high density, and 151.45 g m−2 in low density. The yield main components showed a different response to plant density modification; the grain number exhibited a strong variability and was positively associated with final grain yield (p<0.05) while the grain weight was not affected.
