In order to study the intercropping of basil (Ocimum basiilicum L.) and cowpea (Vigna unguiculata L.) under different levels of nitrogen supply and weed competition conditions, a field experiment was carried out in split-split plot arrangement based on a randomized complete block design with three replications during 2010 and 2011 at Sari Agricultural Science and Natural Resources University. ...
Allocation methodological choices in Life Cycle Assessment (LCA) is a relevant issue for the Circular Bioeconomy context. The recent Product Environmental Footprint Guide from European Commission includes Formula (CFF) as new way to deal with energy recovery/recycling processes. This paper investigated CFF vs. other different LCA allocation methods Brazilian briquette production. A cradle-to-ga...
Using water and fertilizer management at the farm level can be increased water use efficiency and reduce the volume of drainage water, fertilizer losses, and other pollutants in farmland with deep underground drains such as Khuzestan agro-industrial Companies. In the present study, a comprehensive simulation model for the water cycle and the nitrogen dynamics modeling was used for water and fer...
The role of grassland ecosystems as net sinks or sources of greenhouse gases (GHGs) is limited by a paucity of information regarding management impacts on the flux of nitrous oxide (N(2)O) and methane (CH(4)). Furthermore, no long-term evaluation of net global warming potential (GWP) for grassland ecosystems in the northern Great Plains (NGP) of North America has been reported. Given this need,...
Wetland rice cultivation contributes significantly to global warming potential (GWP), an effect which is largely attributed emissions of methane (CH 4 ). Emerging technologies for wetland production such as conservation agriculture (CA) may mitigate greenhouse gas (GHG) emissions, but the effects are not well defined. Investigations were carried out in irrigated (Boro rice) field fifth crop aft...
In order to determine the interaction of residual nitrogen (N) and different N rates on seed and oil yield of rapeseed, an experiment was conducted at Shahrekord University, Shahrekord, Iran, in 2008-2009 growing season. The experimental design was split plots arranged in randomized complete block design with three replications. Seven treatments of residual N (217, 435 and 652 kg/ha from urea...
in the present experiment, the effects of nitrogen and phosphor fertilizer application in two methods of furrow and trickle irrigation on the yield and quality of sugar beet seed cultivar 7233 were studied. the experiment was conducted as a split factorial in a completely randomized block design with three replications during 2003 and 2004 in hamedan province. main plots were allocated to irrig...
BACKGROUND: Bio-fertilizers being essential components of organic farming play vital role in maintaining long term soil fertility and sustainability.OBJECTIVES: Study yield and growth indices of sorghum in response to consume chemical fertilizer and Nitroxin bio-fertilizer.METHODS: This research was conducted via split plot experime...
in order to evaluate the effects of different levels of potassium and nitrogen on nitrogen use efficiency (nue) and yield of rapeseed (hyola 401), a field experiment was conducted at rice research institute of iran (rasht) in a factorial experiment based on a complete randomized block design with 3 replications for two years (2008-2010). the first factor was pure potassium fertilizer in three l...
