چکیده
|
A field study was conducted at new developmental farm (ndf) at the university of agriculture peshawar-pakistan during winter 2013. the aim of this study was to evaluate the influence of grazing on wheat yield, yield components, lodging and related weeds. the experiment was laid out in randomized complete block design (rcbd) with 10 replications. results of this experiment indicated that 70 days post sowing grazing declined tillers m^-2 by 13.32%, spikes m^-2 by 23.85%, plant height by 24.16%, grains spike^-1 by 14.97%, 1000 grains weight by 12.22%, grain yield by 22.16%, biological yield by 26.03% and lodging by 94% whereas weeds fresh and dry weight (g m^-2) were increased by 54.7 and 60.25% respectively. keeping in view the negative aspects of grazing on crop growth, it is therefore, recommended that wheat crop may not be used for grazing.
