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...

abstract in order to evaluate of yield and yield components of eight wheat cultivars against flix weed (descurainia sophia), an experiment was conducted using a factorial arrangement of treatments in a randomized complete block design with four replications during 2003-2004 growing season in varamin region. the wheat cultivars were tabasi, roshan, karaj2, azadi, niknejad, mahdavi, shiraz and pi...

S Studies evaluating the effectiveness of herbicides on weed control, coupled with sustainability management system, are great importance. The present study aims to evaluate efficacy post-emergence applied maize while inferring treatments employing an ecological approach. experiment was installed in a randomized block design four replications. consisted application atrazine at dose 1500 g ha-1;...

in order to evaluate the effects of intercropping of maize- peanut, weeding and their planting design on weed population dynamics, an experiment was conducted as a factorial experiment in the form of rcbd with three replications at the research farm of agriculture center of zabol university (iran) in 2012. the treatments including sowing system in four levels as first factor  (sole maize, sole ...

Livestock is an important sector of agriculture, but good quality forage is one of the major limiting factors for the growth of this industry. Studies were conducted to compare the forage quality of maize and legumes sown in pure stand and in mixture in randomized complete blocks during 2005 and 2006 at the University of Agriculture Faisalabad, Pakistan. Maize (Zea mays L.) and three legumes [c...

Eastern star clover (Trifolium dasyurum C. Presl.) is a new pasture legume developed for use in short phases between extended cropping sequences in Western Australian dryland agriculture. Its delayed germination provides an opportunity to obtain almost complete control of the highly-competitive crop weed rigid ryegrass (Lolium rigidum Gaudin) through non-selective herbicide application and/or g...

Scolothrips longicornis Priesner is one of the important predators of tetranychid mites with a wide distribution throughout Iran. Life table and population growth parameters of S. longicornis feeding on two-spotted spider mite, Tetranychus turkestani Ugarov & Nikolski were investigated under laboratory condition (26±1oC, 65±5% R.H. and 16L: 8D). To carry of these experiments, S. longicornis col...

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...
