Abstract: This study was conducted to evaluate the effects of planting density and planting pattern on weed species, weed density and weed biomass, growth and cob yield of baby corn. The field experiment was conducted in 2020 spring in Gia Lam, Ha Noi using a split-plot design with three replications. The main plot was planting densities with four levels: 138,888 plants ha-1, 111,111 plants ha-1, 92,593 plants ha-1, and 79,365 plants ha-1. The sub-plot factor was two planting patterns: quadrate planting and triangular planting. The results showed that increasing planting density suppressed weed growth while increasing corn yield. However, the planting patterns did not affect the weed growth as well as the growth and yield of corn. With the same planting pattern, increasing planting density significantly reduced weed density and weed biomass, and increased yield of baby corn. The highest corn yield (1.69-1.77 tons/ha) was obtained at the planting density of 111,111-138,888 plants/ha combined with quadrate planting or triangular planting
