(1) Ipomoea hederacea, a common weed in cultivated fields of eastern North America, disappears quickly following abandonment of farming. (2) The effects of competition and nitrogen addition on the growth and reproduction of I . hederacea were studied during the first year of abandonment. (3) Competition and fertilization had significant absolute effects on almost all biomass variables measured ...
In order to investigate the effect of quinoa seed inoculation on photosynthesis rate, yield and competitive ability with weeds, an experiment was conducted as split-plot based on a randomized complete block design with three replications at experimental farm of School of Agriculture, Shiraz University, Shiraz, Iran during 2020 growing season. Treatments were three levels of weed management as m...
Borage (Borago officinalis L.) is a valuable medicinal plant and its production to meet the needs of the pharmaceutical industry has a high value. The objectives of this work were to evaluate water quality and different fertilizer systems on some physiological and biochemical characteristics of borage. The experiment was conducted as a split-plot arrangement based on compelet block design with ...
One of the negative effects of water stress on growth and crop production is micronutrient uptake reduction by plant root. Therefore, to evaluate the effect of foliar application of Fe and Zn on some physiological and morphological characteristics of red bean (Akhtar cultivar) under drought stress this experiment was designed as a split plot in a completely randomized block design with three re...
The negative effects of water stress, reduced water use and nutritional disorders in plants. So in order to study the effects of foliar application of iron and manganese on some morphological and physiological characteristics of Mungbean (cultivar beam) under water deficit stress, this experiment was conducted in the Faculty of Agriculture of Tarbiat Modares University as randomized complete bl...
the aim of this study was to determine the monthly dtr mass load of amphetamine-type compounds in poland as well as an investigation of cyclical behaviour by using time series analysis and especially trends analysis.amphetamine, methamphetamine and mdma (ecstasy) were detected in wastewater samples collected from the main wastewater treatment plant in the city of poznan using liquid chromatogra...
this experiment was conducted at the agricultural research farm of isfahan university of technology in 2007-2008 to evaluate the effects of seed treatment and the levels of irrigation regimes on three safflower cultivars. a split plot factorial arrangement was used in a randomized complete block design with three replications. main-plot consisted of three irrigation regimes (60, 105 and 140 mm ...
In order to study the effects of water stress and different amounts of sulfur fertilizer on grain yield, nutrient status and chlorophyll content in black cumin (Nigella sativa L.) a field experiment as split plot design with three replications was conducted at Ghaen city in 2009. Treatments included three levels of irrigation after 50, 100 and 150 mm evaporation from Class A pan as main plot an...
In order to evaluate effect of plant density and water deficit on the growth, yield and yield component of soybean, an experiment was carried out in split plot design based on RCBD with four replications at the research station of Seed and Plant Improvement Institute in Karaj-Iran in 2006. In this experiment, water deficit treatment in three levels was placed as main plot (water withholding at ...
