Weed interference in annual cropping systems can be highly variable from year-to-year, as well as spatially heterogeneous. These factors have confounded efforts to develop simple methods for predicting competitive outcomes early in the growing season. A 2-year study was conducted with maize in competition with four annual weed species (Setaria faberi, Abutilon theophrasti, Chenopodium album and...

Weed interference is a major threat to rice production, leading high yield reduction and reduced profitability. Therefore, field experiments were conducted evaluate the effect of different timings weed control on growth upland in 2015 2016 cropping seasons. The treatments consisted periods when crop was allowed be weed-infested for first 3, 6 9 weeks after sowing (WAS) weeds controlled WAS. Two...

Four million hectares of wheat are planted after cotton and rice in Pakistan. Little research has been done on the aronomy of wheat following these crops on a cropping pattern basis. Both of these crops delay wheat planting, and it is estimated that 40–50 kg of wheat grain is lost for every day that planting is delayed past 20 November. Current recommendations for land preparation, fertilizer u...

Abstract Background Low plant density and wide intra-plant spacing in traditional cowpea cropping systems are among the factors responsible for low yield on farmers’ fields. Sole improved intercropping have been advocated last few years to increase dry savannah areas of Nigeria. This study investigated level adoption high yielding including that influenced their use perceived production constra...

Cropping systems in Western Australia (WA) are strongly dominated by cereals (wheat, barley and oaten hay) and are inextricably linked to soil quality and moisture supply. So a major research challenge is to devise cropping systems that improve soil health and maximise water-use efficiency. For a profitable and sustainable production system there is a clear need for ‘break crop’ to provide a pe...

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...

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...
