    Abstract


    This study evaluated the effect of different of mulching materials and planting densities on weed species, weed density and weed biomass, growth and grain yield of quinoa. The field experiment was conducted in Gia Lam, Ha Noi, consisting of two factors and using a randomized complete block design (RCBD) with three replications. Mulching materials consist of weed stem and leaves mulch, rice straws mulch and black plastic mulch, and non-mulch. Planting densities were sown at three different levles: 80.000 plants ha-1, 100.000 plants ha-1, and 133.333 plants ha-1. The results showed that mulching materials such as weed stem and leaves, rice straws or black plastic in combination with a planting density of 100.000 plants ha-1 significantly reduced weed density and weed biomass. Additionally, these conditions enhanced the growth and grain yield of quinoa.
