Amaranthus retroflexus or redroot pigweed is a second generation lignocellulosic fuel. Each biomass sample (leaves, inflorescences and stems) was pyrolyzed in lab-scale furnace, nitrogen atmosphere under non-isothermal conditions at heating rates of 10 °C/min until the furnace temperature reached 550 °C. The pyrolysis characteristics three major components were also studied through thermogravim...

Effective weed management depends on correct control timing, which seedling emergence dynamics. Since soil temperature and moisture are the two main factors that determine germination, hydrothermal time model can be used to predict their emergence. The aim of this study was estimate base (Tb) water potential (?b) for germination Chenopodium album, Amaranthus retroflexus, Setaria pumila, Panicum...

a two year field experiment was carried out to evaluate the effects of municipal waste compost (c), composted cattle manure (m), and nitrogen (n) on growth and composition of weeds in a corn field in shiraz using a split-split plot design with 3 replicates. visual inspection of the plots showed that the manure treatments neither introduced new weed species nor increased weed density more than t...

abstract in order to study the effect of different organ extracts of fenugreek (trigonella gracum (on germination of some crops and weeds, an experiment was conducted in completely randomized design with 3 replications. factors included 4 species soybean (glysin max),sesame ( sesamus indicum) , pigweed (amaranthus retroflexus) and velvetleaf (abotilon teophrasti) and the extract of different fe...
