BACKGROUND Second generation (2G) bioenergy from lignocellulosic feedstocks has the potential to develop as a sustainable source of renewable energy; however, significant hurdles still remain for large-scale commercialisation. Populus is considered as a promising 2G feedstock and understanding the genetic basis of biomass yield and feedstock quality are a research priority in this model tree sp...

in order to study yield and yield components in intercropping bean (phaseolus vulgaris l.) and sweet basil (ocimum basilicum l.) and evaluating effect of intercropping on weed control, a field experiment was conducted at the agricultural research station, ferdowsi university of mashhad during growing season of 2008. treatments: included 1- sole crop of bean 2- sole crop of sweet basil 3- strip ...

studies manipulating the source-sink relationships during post anthesis in wheat have shown inconsistent results, concluding that wheat yield could be either sinkor source-limited. the aim of this study was to determine source limitation degree of 36 iranian wheat cultivars andto investigate their intrinsic compensatory mechanism in response to source size reduction. a split plot design based o...

Soil salinity adversely affects the growth, yield, and quality parameters of sugar beet, leading to a reduction in root yields. Improving physical chemical properties salt-affected soils is essential for sustainable cultivation beet production. A field experiment was conducted at Delta Sugar Company Research Farm, El-Hamool, Kafr El-Sheikh, Egypt, evaluate response application filter cake treat...

Drought is one of the major limiting factors in wheat production in Pakistan. Five commercial wheat varieties; Chakwal-97, Inqilab-91, Margalla-99, NR-234 and Wafaq2001 were grown in pots in glasshouse. Plants were subjected to three consecutive drought cycles at tillering, pre-anthesis and milky growth stages by withholding water till leaf rolling started. Measurements of physiological respons...

Objective: Environmental and economic challenges resulting from the application of nitrogen fertilizers have increased Concerns about its productivity in the agricultural systems. Thus an experiment in order to investigate ability SSM-Wheat for simulation growth and yield of wheat (cultivar N-87-20) in response to fertilizer nitrogen in the direction decrease Pollution environm...

Regional scale vegetation monitoring and yield forecasting require the estimation of biophysical parameters, such as Leaf Area Index (LAI), biomass and canopy water content (CWC). The CWC is also targeted for fire risk and drought monitoring. This work presents a methodology for jointly retrieval of Canopy Water Content (CWC) and Leaf Area Index (LAI) from coarse resolution satellite data. The ...
