Trianthema portulacastrum L. (Family: Aizoaceae), commonly known as horse pursulane is a troublesome broadleaved weed in India. Aggressive growth of this type of weeds with high invasion potential it becomes an important constraint in crop cultivation. Yield losses are most severe when weeds and crops emerge simultaneously and compete with each other for resources. Crop yield usually decreases with increase in weed density and interference duration. The competition effect of Horse pursulane on growth and yield attributes of maize experiment was conducted during January 2018 at Agricultural College and Research Institute, Tamil Nadu Agricultural University, Madurai. Treatments like weed free check, horse pursulane densities (7, 14, 21, 28 and 35 m-2) and unweeded check were laid out in Randamized block design (RBD) with three replications. The results indicated that, higher weed density m-2 reduce the growth parameters like LAI and dry matter production and yield attributes. Weed free check recorded higher grain yield of 8577 kg/ha. The yield loss (%) was higher (44.78%) in T6 with 35 plants m-2 than other weed density treatments. Horse pursulane infests maize heavily, causing enormous yield losses and threatens the sustainability of maize production.
