the influence of nitrogen and weed interference periods on corn
abstract in order to evaluate the influence of nitrogen application and duration of weed interference on corn (zea mays l.) yield and yield components, a field study was conducted in 2004 at the ferdowsi university of mashhad research field. the experimental design was a randomized complete block with a factorial treatment arrangement replicated three times. nitrogen fertilizer was applied at r...
متن کاملEffect of Nitrogen and Weed Interference on the Quality and Quantity of Sugar Beet (Beta vulgaris L.)
In order to determine the effect of weeds interference and nitrogen on the sugar beet growth and yield, a field study was performed in the 2010 growing season as a split plot design based on RCBD with three replications in Hana region (Semirom, Esfahan). Treatments were four levels of nitrogen from urea source as the main factor (0, 70, 150 and 210 kg ha-1) and weed interference at five levels ...
متن کاملResidual Soil Nitrogen and Nitrogen Response of Corn on Sandy Loam Soil
Groundwater contamination is an ever-increasing concern on a national level as well as locally. Increasing amounts of nitrate-nitrogen (NO3-N) being delivered by rivers, including the Mississippi, have resulted in an oxygen-depleted area or hypoxic zone in the Gulf of Mexico. (Turner and Rabalais, 1994b). This nutrient loading has caused nitrogen-limited phytoplankton to bloom. Decom-position o...
متن کاملEffects of manure, municipal waste compost and nitrogen on weed communities in corn (Zea mays L.)
A two year field experiment was carried out to evaluate the effects of municipal waste compost (C), composted cattle manure (M), and nitrogen (N) on growth and composition of weeds in a corn field in Shiraz using a split-split plot design with 3 replicates. Visual inspection of the plots showed that the manure treatments neither introduced new weed species nor increased weed density more than t...
متن کاملDepth of nitrogen fertiliser placement affects nitrogen accumulation, translocation and nitrate-nitrogen content in soil of rainfed wheat
A field experiment was conducted to examine the effects of different depths ofnitrogen (N) fertiliser placements on N accumulation, remobilisation and NO3−-Ncontent in soil of rainfed wheat. Nitrogen was applied on the surface (D1) and inthe 10 cm (D2), 20 cm (D3) and 30 cm (D4) soil layers from 2010 to 2012.Compared with D1 and D2, D3 and D4 treatments obtained significant higher Ndistribution...
