Glyphosate is the world's most important herbicide, with many uses that deliver effective and sustained control of a wide spectrum of unwanted (weedy) plant species. Until recently there were relatively few reports of weedy plant species evolving resistance to glyphosate. Since 1996, the advent and subsequent high adoption of transgenic glyphosate-resistant crops in the Americas has meant unpre...
introduction: depressive disorder is a prevalent psychiatric disorder, which affects 21% of the world population. the presently using drugs can impose a variety of side-effects including cardiac toxicity, hypopiesia, sexual dysfunction, body weight gain, and sleep disorder. during the last decade, there is a growing interest in the therapeutic effects of natural products on mental disorders. am...
ریزش سالیانه بذور علفهای هرز و تجمع آنها در خاک بانکبذر پایداری را تشکیل میدهند که میتواند سالهای متمادی منشاء آلودگیهای مزارع به علفهای هرز باشد. به منظور بررسی ارتباط بین بانک بذر خاک و جمعیت مزرعهای گونههای مختلف علفهای هرز مزارع پنبه، آزمایشی دوساله (84-1383) در سطح استان گلستان انجام شد. در مجموع دو سال 49 گونه علفهرز متعلق به 19 خانواده گیاهی در مزارع پنبه شناسایی شدند. بر اسا...
The present investigation has been designed to prepare the organic fertilizer from fish waste and study efficacy of on growth yield plants Amaranthus dubius (amaranthus) Trigonella foenum- graecum (coriander). Fish wastes collected slaughter house converted into nutrient quality in terms protein, carbohydrate, nitrogen, phosphorous potassium contents were tested using standard procedures. For a...
salinity is one of the environmental factors that have a critical influence on the plant emergence and plant growth and establishment. the determination of salinity tolerance threshold is a useful criterion to choose soil and irrigation water for cultivation of halophytes. in order to determine salinity tolerance threshold in amaranthus retrofelexus, an experiment was performed in greenhouse ba...
Plot-scale field studies were conducted to evaluate the efficacy of steam for the control of cropland weeds in comparison with common herbicides. Weed densities, biomass, or emergence after treatment were measured. Steam (3,200 kg/ha, energy dosage equivalent to 890 kJ/m2, speed of 0.8 m/s) and glyphosate (560 g ai/ha) gave similar control (. 90%) of seedling common lambsquarters and seedling r...
Amaranthus species are of underutilized orphan crops grown in tropical and sub-tropical regions the world. Benin’s most appreciated cruentus L. «local» cultivar is susceptible to saline stress. This study aimed create genotypes agronomically, at least, as good useful for further tolerance breeding using mutation breeding. The morphological diversity among 19 gamma-irradiated A. mutant lines (co...
