Light use efficiency (LUE) defines the vegetation of converting radiative energy into biochemical through photosynthesis. Estimating maximum LUE (εmax) is critical yet challenging for quantifying gross primary production (GPP) using LUE-based models. This study describes an analytical method estimating εmax based on water (WUE) as determined by plant and carbon gain. Unlike other complex parame...

Phytoremediation is a promising technology to remediate carcass burial sites where deep soil layers are contaminated with nitrogen (N), phosphorus (P) and other potential contaminants by leachate. The current study was conducted to examine the remedial efficiency of two different woody plants, poplar (Populus euramericana) and willow (Salix alba), by employing the deep-planting technique for th...

this study was carried out to investigate the effects of different irrigation regimes and planting methods on yield, yield components, morphological traits, and storage characteristics of a local onion cultivar, namely, goli ghesse. the experiment was conducted as a factorial split plot design with rcbd arrangement in four replications and for three years at kheirabad research station. irrigati...

in order to study of effects of integrated biological and chemical  fertilizers on  fertilizer use efficiency, grain yield and related traits to  grain growth of barley (hordeum vulgaris l.), a factorial experiment was conducted based on randomized complete block design with three replications in research farm of the faculty of agriculture sciences, university of mohaghegh ardabili in 2012. tre...

Water, salinity and nitrogen are the major factors affecting maize production in arid and semi-arid areas. The objectives of this study were to investigate the effects of different water, salinity and nitrogen levels on yield-water relationships, water use, water productivity (WP), water use efficiency (WUE) and water uptake reduction function by maize hybrid SC-704 in a semi-arid area and ...

Dryland winter wheat (Triticum aestivum L.) production plays an extremely important role in the southeast of Loess Plateau. Planting patterns have great influence on improving soil water storage and yield, should be matched with different seeding rates. In order to assess effect sowing methods drought resistance stable yield dryland wheat, a field experiment was conducted Wenxi County Wheat Exp...

abstract in order to analyse of soil volume humidity and water potential of turf using of different amounts of water absorbent polymer in sort of acryl amid potassium, an experiment conducted at research farm of meybod azad university in 2005. the experiment was conducted in randomized completed block design in four levels of polymers of 3, 6, 12 and 24 gr/m2 and 0 gr/m2 of polymers was conside...

eld to prepare for planting, while the tractor and crew on the right are planting trees. This method provides a weed-free soil immediately after planting for preemergence herbicide applications. W eeds reduce the value of nursery crops. They compete with crops for nutrients, light, and water. Some vine weeds climb nursery crops, requiring excessive labor for hand removal. Most serious are peren...

Information on the effect of planting date and irrigation on soybean [Glycine max (L.) Merr.] seed composition in the Early Soybean Production System (ESPS) is deficient, and what is available is inconclusive. The objective of this research was to investigate the effects of planting date on seed protein, oil, fatty acids, sugars, and minerals in soybean grown under irrigated (I) and non-irrigat...
