 Abstract 


A field trial was conducted under drip irrigation over two seasons in 2019 and 2020, at the experimental station of the Department of Agricultural Research in Botswana, to evaluate the effects of planting density on yield and some agro-physiological attributes in common bean (Phaseolus vulgaris L). The experimental design was a split-plot with three replications, and two genotypes (DAB564 and DAB520) as main treatments and three planting densities as sub-treatments; 44,444 plants/ha (0.75 m between rows and 0.3 m between plants), 66 666 plants/ha (0.75 m between rows and 0.2 m between plants) and 133,333 plants/ha (0.75 m between rows and 0.1 m between plants). It came out from data recorded that, over both cropping seasons, common bean genotypes were significantly influenced by the planting density. The Planting density × Genotype effect was also significant which means that both genotypes responded differently to the planting density no matter the cropping season considered.
