Most crops are affected by various factors, plastic mulch emerges as an alternative, causing a positive impact on the temperature in root zone, microbial life and physical properties of soil associated with improvement crop yield. The objective research was to evaluate yield soybean (Glycine max L.) under conditions. Geotemperature parameters, net heat flow from morphological variables were ana...

in order to study the effect of soil nitrogen content and water hardness on glyphosate efficacy on common lambsquarter (chenopodium album l.) and redroot pigweed (amaranthus retroflexus l.) control, an experiment was carried out as a completely randomized design in a factorial arrangement with three replications. experimental treatments were included soil nitrogen content (18, 50, 90, 200 and 3...

The field experiments were conducted during the wet season of 2015 and 2016 (June to October) at Agricultural Farm, Institute Agriculture, Visva-Bharati, Sriniketan, India study impact integrated use weed mulch herbicide with closer spacing on growth yield direct seeded dry sown rice (Oryza sativa L.) cultivar MTU 1010. experiment consisted twelve treatments involving sole or application pre-em...

in order to investigate the efficacy of split, reduced and whole rates of oxyfluorfen in controlling redroot pigweed (amarnthus retroflexus) and also to evaluate possible soybean (glycine max) injuries a experiment was conducted in research greenhouses of karaj collage of agriculture, university of tehran in 2005. treatments included oxyfluorfen doses at 0.25, 0.5, 0.75 and 1 l/ha in one stage ...

in order to evaluate the effect of different sources and rates of nitrogen the growth and biomass production of purslane, a randomized complete block design was conducted with three replications at the agricultural research farm of shahrekord university in 2012. fertilization treatments were consisted of control (no n amendment), 30 and 90 kg n ha-1in the form of urea fertilizer, 30 and 90 kg n...

to study the effect of glyphosate application rate and timing on johnsongrass (sorghum halepense) vegetative and reproductive growth, three experiments were conducted in field, greenhouse, and laboratory in the agronomy department of university of tehran, karaj, in 2007 & 2008. in each experiment, treatments were arranged in completely randomized (greenhouse & laboratory) and completely randomi...

There is an increased interest in the use of soil-biodegradable plastic mulch due to limited disposal options for conventional polyethylene mulch. However, information about impact continuous on environment limited. Here, we show effects soil and groundwater quality from mulches crop production four consecutive seasons. Two products were assessed at two locations (Knoxville, TN Mount Vernon, WA...
