crops that better tolerate weed competition or preempt resources from weeds may reduce dependence on herbicides and benefit an integrated weed management program. a field trail was conducted to determine the morphophysiological characteristics affecting tolerance and weed suppressive ability of some winter wheat cultivars in competition with rocket. the experimental treatments consisted of eigh...

The need to increase cowpea production solve the menace of malnutrition is a global challenge and land limitations have also made intercropping indispensable. Field trials were carried out at Teaching Research Farm, Kwara State University, Malete, National Centre for Agricultural Mechanization (NCAM) Idofian evaluate growth yield cultivars sorghum with their competitive behavior in cowpea-sorgh...

in order to determine the responses of morphological characteristics, yield and yield components of rapeseed (brassica napus l.) to plant density and weed interference duration, a factorial experiment was conducted using a randomized complete block design with 3 replications at the rice research institute of iran (rrii) in rasht, in the 2008 growing season. the factors comprised plant density a...

Poppy seed production is susceptible to abiotic and biotic stress weed infestation, which introduces the risk of total crop failure. For purpose minimization, poppy was grown in additive intercropping systems with early late sown white clover spring barley at three different densities a year field trial assess their roles cropping while adding ecological benefits rotation. yielded between 798.7...

Crop rows oriented at a right angle to sunlight direction (i.e., east–west within the winter cropping system in Western Australia) may suppress weed growth through greater shading of weeds in the interrow spaces. This was investigated in the districts of Merredin and Beverley, Western Australian (latitudes of 31u and 32uS) from 2002 to 2005 (four trials). Winter grain crops (wheat, barley, cano...

Seed production of annual weeds persisting through cropping phases replenishes/establishes viable seed banks from which these weeds will continue to interfere with crop production. Harvest weed seed control (HWSC) systems are now viewed as an effective means of interrupting this process by targeting mature weed seed, preventing seed bank inputs. However, the efficacy of these systems is directl...
