Abstract Alternative strategies are needed for management of glyphosate-resistant (GR) horseweed in soybean. Integrating a cereal rye cover crop with soybean planted narrow rows may improve control and reduce herbicide selection pressure herbicide-resistant biotypes. Four site-years experiments were conducted Michigan to determine whether fall-planted terminated glyphosate 1 wk prior (early ter...
increasing level of carbon dioxide co2 due to industrial activity is primarily cause of global warming. planting artoplex lentiformis can help to reduce atmospheric co2 buildup partly replacing use of fuels and by carbon storage. the objective of this study was to determine the effects of row spacing on carbon storage. a split- plot design with three replications included three row spacing (2×2...
abstract sensitive and precise voltammetric methods for the determination of trace amounts of furaldehydes, mainly as furfural (f) and 5-hydroxymethyl-2-furaldehyde (hmf), in waste waters and other matrices is described. determination of total furaldehyde at < ?g g-1 levels in alkaline buffered aqueous media was individually investigated. by the use of ordinary swv and adsorptive square wave ...
This study had the objective to evaluate effect of irrigation and fertigation (N) in crop yield its impact on total cost, addition influence conductivity hydraulic capacity logarithmic an Oxisol under vinasse application cultivated with sugarcane (second year), state Goiás, Brazil. The experimental design comprised randomized blocks a 5 × 2 factorial scheme, four replications. Treatments consis...
this work is presented in five parts. in the first part preparation of the starting complex [pt(c^n)cl(dmso)], 1, in which c^n = n(1),c(2?)-chelated, deprotonated 2-phenylpyridine, and dmso = dimethylsulfoxide, and its reaction with 1 equiv of the biphosphine ligands bis(diphenylphosphino)amine, dppa, or bis(diphenylphosphino)methane, dppm, to give the complex [pt(c^n)cl(dppa)], 2, or [pt(c^n)c...
This experiment was conducted at the Agricultural Research Station of Isfahan University of Technolgy in 2006 to evaluate the effects of planting pattern and the level of soil moisture on two safflower cultivars. A factorial split plot arrangement was used in a randomized complete block design with three replications. Two planting patternS (flat and bed planting) and two levels of soil moisture...
in order to evaluate the effects of different planting dates and biological fertilizers on yield, yield components and essential oil content in cumin (cuminum cyminum) and fenugreek (trigonella foenum-graecum) intercropping, an experiment was conducted in a split-plot factorial arrangement in a randomized complete block design with three replications in research farm of ferdowsi university of m...
A numerical method called Multiple Attribute Decision Making (MADM) has been used for rational selection of a cotton harvester out of a finite number of cotton harvesters available the world over. In India, efforts are being made to design and develop a commercial cotton harvester to harvest selected cotton varieties sown by adopting common agronomic practices locally for cotton cultivation. Th...
