Abstract

Growth stimulation anticipated to ultra-low doses of various herbicides in some crop species has been observed equally in under control and field conditions; however available data of hermetic affects on growth of weeds is extremely restricted. This study explores the promotive impact of low doses of atrazine on Tribulus terrestris growth. Pot experiments were trialed at Agronomic Research Area, collage of Agriculture, University of Sargodha, during 2019. Six different concentrations of atrazine [0, 5, 10, 20, 40 and 80 g active ingredient  ha-1] were employed as post emergence herbicides at weeds stages having 3- 4 leaves under two different water regimes (60 % and 100 % water concentrations). Results revealed that increase in plant chlorophyll content, fresh and dry weight, root and shoot length were observed after spraying of atrazine @ 5, 10 and 20 g active ingredient ha-1 at 100 percent (%) water concentration. Atrazine doses exceeding 20 g active ingredient ha-1 destructively disturb the growth of Tribulus terrestris.
