To study the effects of vegetable oils on the performance of Imazethapyr (a herbicide with a relatively high amount of residue in the soil and environment) in barnyardgrass (Echinochloa crus-galli Beauv) control, a factorial experiment based on completely randomized design with four replications was conducted in the Research Greenhouse of College of Agriculture, Birjand University, Birjand, Ira...
در سالهای اخیر، علایم بیماریهای ویروسی شامل موزاییک مخطط، بدشکل شدن پهنک برگ و لاغری خوشه در سطح وسیعی از مزارع غلات استان گلستان مشاهده شدهاند. بهمنظور بررسی علل این عوارض، اقدام به ردیابی ویروس موزاییک مخطط گندم (WSMV) در میزبانهای زراعی از جمله گندم و علفهای هرز غالب مزارع شامل سوروف (Echinochloa crus-galli)، قیاق (Sorghum halepense)، دمروباهی (Setaria glauca)، علف خرچنگی (Digitaria s...
Dicamba plus glyphosate (DpG) tank mixture has been widely adopted for broad-spectrum weed control. However, recent studies indicated antagonistic interactions between these herbicides. Furthermore, little is known about the effect of non-ammonium sulfate water conditioner (non-AMS WC) adjuvant on activity DpG mixture. Thus, present study was elaborated to evaluate (1) interaction mixtures comb...
Weed behaviour in crop fields has been extensively studied; nevertheless, limited knowledge is available for particular cropping systems, such as no-till systems. Improving weed management under conditions requires an understanding of the interaction between residues and seedling emergence process. This study aimed to evaluate influence maize wheat residues, applied three different quantities (...
in recent years, symptoms of a viral disease including streak mosaic, leaf blade malformation, and thickness (scrawniness) of raceme have been observed in the vast areas of grain fields in golestan province. in order to identify the causes of this disease, detection of wheat streak mosaic virus (wsmv) in cultivated hosts including wheat, dominant weeds of fields involving barnyardgrass (echinoc...
Solid-based residues (SBRs) of Cordyceps militaris are often considered as waste after the cultivation fruiting body. To demonstrate value this by-product, different ratios two favorable green solvents (EtOH and water) were employed to optimize yields cordycepin (Cor) adenosine (Ado) investigate relevant activities plant growth inhibition (allelopathy), antioxidants, xanthine oxidase. The SBR e...
Preliminary data from newly excavated archaeological site no. 8 in Kraków-Górka Narodowa (southern Poland) show that two main phases of Early Neolithic occupation can be distinguished based on pottery finds, one associated with the Malice culture and other Pleszów- Modlnica group Lengyel culture. These are presented along lithic materials discussed context results archaeobotanical analysis. Cha...
به منظور بررسی غنای گونهای علفهایهرز در مزارع محصولات تابستانه (ذرت، برنج، لوبیا، یونجه) استان ایلام، 21 مزرعه در شهرستانهای سرابله، درهشهر و دهلران که دارای الگوی اقلیمی متفاوتی بودند طی سال زراعی 89-1388 انتخاب گردید و شاخصهای جمعیتی و پراکنش آنها بررسی شد. در هر مزرعه مشخصات جغرافیایی توسط دستگاه GPSثبت گردید. نتایج نشان داد که در مزارع ذرت استان 26 گونه علفهرز وجود دارد. بر اساس شا...
