Effect of Integrated Weed Management and Nitrogen Levels on Weed Infestation and NPK Depletion by Weeds in Onion

Effect of tillage systems on weed infestation of durum wheat

Weed infestation of durum wheat was determined in the systems of conventional tillage(CT), reduced tillage (RT) and herbicide tillage (HT). Cultivations measures performed after theharvest of the previous crop included shallow ploughing (at a depth of 10-12 cm) and pre-winterploughing (25-30 cm) in the CT system; only field cultivation (10-15 cm) in the RT system; andspraying with glyphosate (R...

True integrated weed management

Using the simplest of definitions, integrated weed management has been described as “putting components [of weed control] together, not taking them apart.” Yet, weed science has stopped at the “field edge” in assembling the components into a truly integrated approach. What is keeping weed scientists from developing real integrated weed control regardless of space and time? The answer to this qu...

Weeds and Weed Management in India - A Review

India has a wide range of agroclimates and soil types. The highly diverse agriculture and fanning systems are beset with different types of weed problems. Weeds cause 10-80% crop yield losses besides impairing product quality and causing health and environmental hazards. Invasive alien weeds are a major constraint to agriculture, forestry and aquatic environment. Crop-specific problematic weeds...
