The estrogenic isoflavones of soybeans and their glycosides are products of the shikimate pathway, the target pathway of glyphosate. This study tested the hypothesis that nonphytotoxic levels of glyphosate and other herbicides known to affect phenolic compound biosynthesis might influence levels of these nutraceutical compounds in glyphosate-resistant soybeans. The effects of glyphosate and oth...
In order to determine the optimal rates of Pertilachlor and Sunrice-plus herbicides for weed control of rice (Oryza sativa Var.Tarom Hashemi), a factorial experiment was conducted with a randomized complete block design with four replications in Rice Research Farm of Faculty of Agriculture, University of Guilan, Rasht, northern Iran. The first factor was weed control treatment which consiste...
A Palmer amaranth (Amaranthus palmeri S. Watson) biotype has evolved resistance to photosystem (PS) II- (atrazine) and 4-hydroxyphenylpyruvate dioxygenase (HPPD)-inhibiting herbicides (mesotrione, tembotrione, and topramezone) in maize seed production field in Nebraska, USA. The objectives of this study were to determine the effect of soil residual pre-emergence (PRE) herbicides followed by (fb...
In order to evaluate the effect of biofertilizers (nitroxin and phosphate barvar2), vermicompost and chemical fertilizers on the quantity and quality traits of sugar beet (Beta vulgaris L.), an experiment was conducted in randomized complete block design (RCBD) with 13 treatments and three replications at Agricultural and Natural Resources Research Station of Miandoab, Iran in 2015. The treatme...
The study compares energy production from semi-natural grasslands by the integrated generation of solid fuel and biogas from biomass (IFBB) through mechanical separation of the biomass with the dry fermentation (DF) and hay combustion system (HC). In addition, traditional use for beef cattle production and non-refining systems of landscape conservation, i.e. mulching and composting, are conside...
We studied the effects of five thinning treatments (T1 = 5.5, T2 = 11, T3 = 16.5, T4 = 22.5 and T5 = 28.5 m(2) ha(-1) basal area under bark) x two fertilizer treatments (F0 = unfertilized and F1 = fertilized with 400 kg ha(-1) N plus 229 kg ha(-1) P) on growth and water relations of pole-sized Eucalyptus marginata J. Donn ex Sm. trees growing in southwestern Australia. Thinning reduced leaf are...
To investigate the effect of biofertilizers and N levels on yield and yield components of wheat, a two-year study (2012-2013) was carried out in Isfahan by using strip split plot based on randomized complete block design in three replications. Four treatments of biofertilizers (control, Nitroxin, Supernitroplus, and Vacosium seed plus) were assigned as vertical factor and four N levels (0, 25, ...
Effect of potassium and magnesium fertilizers on safflower grain yield was studied, using a factorial experiment based on completely randomized block design with three replications at the Agricultural Research Station of University of Mohaghegh Ardabili in 2011. The treatments consisted of potassium fertilizer with three levels (0, 60 and 120 kg ha-1) and magnesium fertilizer (0, 75 and 150 kg ...
A series of experiments was carried out at Students Farm, Sindh Agriculture University, Tandojam to evaluate the effect of NPK, micronutrients and N-placement on the growth and yield of sunflower during 2005-2006. The sunflower cv. HO-1 was studied under 7 different NPK levels and placement methods (0-0-0 NPK kg ha, 6030-30 NPK kg ha (N as broadcast), 60-30-30 NPK kg ha (N as fertigation), 90-4...
Metam sodium (MS) is often applied to potato fields via sprinkler irrigation systems (water-run, WR) to reduce propagules of soil-borne pathogenic fungi, particularly Verticillium dahliae, to prevent yield loss from potato early dying disease. However, this procedure has not been effective for controlling quality defects in tubers caused by Columbia root-knot nematode (Meloidogyne chitwoodi). I...
