Abstract:

This study was designed to investigate the effect of different plant densities on architectural traits and yield components at the experimental field of ATTC- Lushnja, Albania, and to analyze the associations between plant density and above mentioned traits. Line L-3221 of dry bean (Phaseolus vulgaris) was sown at densities of 15, 20, 25, 30,35, 40 and 45 plants/m² during the growing seasons 2010 and 2011. A randomized complete block design with four replications was implemented. The results showed significant effect of plant density on architectural traits and yield components. In general, increasing plant density leads to reduced values of these traits in single plants, but increases their values per unit area. Although the increase in the plant density leads to a linear reduction of the plant yield components, the yield itself results higher. The densities of 35 and 40 plants per m² are most indicated to obtain the highest dry bean seed yield. Seed yield was highly and positively correlated (r = 0.91**) with plant density, but the yield components of plant were negatively associated with density. Also, significant and negative correlations between plant density and branch/plant (r = -0.93**), node/plant (r = -0.98**) and diameter of plant (r = -0.87**) were observed.
