in order to study the effects of nitrogen and drought stress on yield, yield components and seed quality of corn (hybrid single cross 704) a field experiment was conducted at agricultural research station in islamabad gharb in 2009. experiment design was split plots based on randomized complete block design with three replications. main plots included full irrigation requirement, 80 percent and...

The food industry is interested in new plant-based, non-toxic, additives to substitute synthetic ones. Aiming support the development of H. sabdariffa bio-colorant extracts at an early stage, a cradle-to-gate life cycle assessment (LCA) approach was used evaluate primary energy (CED) and global warming potential (GWP) three extraction processes: maceration (A), ultrasound-assisted (UAE) during ...

in order to investigate the effect of nitrogen fertilizer on tea yield and yield components in supplemental irrigation and rain fed conditions an experiment was conducted at feshalam tea research station in fouman (guilan) during (2008-2010). in this study, line-source irrigation technique and the strip plot experiment on randomized complete block design was used. six levels of nitrogen, zero, ...

effect of different irrigation regimes and nitrogen fertilizer on percentage of grain fatty acids, yield, water and nitrogen use efficiency of pumpkin was studies as split plot based on complete randomized block design with three replications in growing season of 2013. irrigation treatments (320, 420, 600 and 900 mm ha-1) were se as main plots and nitrogen fertilizer (0, 130, 260, 390 and 520 k...

In order to examine the effect of the quantity of Nitrogen fertilizer and bush density on vegetative and productive function of henna medicinal plant (Lawsonia inermis)  factorial experimentation in the form of block plan was carried in three stages in agriculture research center in south of kerman  province in corp of 2012. The first factor containing Nitrogen fertilizer in 4 levels i...

Land-use and agricultural practices affect the soil microbial carbon (C) and nitrogen (N) turnover and hence the biosphere-atmosphere exchange of greenhouse gasses (GHG), namely N2O, CH4 and CO2. In view of the global importance of irrigated agriculture, it is crucial to understand how and to which extent this land-use system interferes with the terrestrial N and C cycles and contributes to the...

Emission metrics aggregate climate impacts of greenhouse gases to common units such as CO2-equivalents (CO2-eq.). Examples include the global warming potential (GWP), the global temperature change potential (GTP) and the absolute sustained emission temperature (aSET). Despite the importance of biomass as a primary energy supplier in existing and future scenarios, emission metrics for CO2 from f...
