A study on the allelopathic tolerance of garden pea varieties to 'Sorghum halepense' (L.) Pers. extracts

The present research study identified garden pea varieties with pronounced tolerance to the allelopatic action of Sorghum halepense. Nine varieties were selected to study the effects of shoot and root weed biomass, applied in three extract concentrations (1, 5 and 10%), on seed germination and initi...
