An experiment entitled "Influence of pre and post-emergence herbicides on weed dynamics, growth and yield of soybean (Glycine max L.)" was conducted in Kharif season 2015 at research farm of BRAUSS, MHOW, (.). The soil of the experimental field was medium black in texture, neutral in reaction (pH ) with normal EC ( dS/m) and medium organic carbon contents ( %) and analysing low in available N (270 kg/ha), medium in available P ( kg/ha) and high in available K (382 kg/ha) contents. Due to dominance of montmorillonite clay content it has high capacity to swell and shrink and high CEC. | Influence of pre and post-emergence herbicides on weed dynamics growth and yield of soybean Glycine max L.
