چکیده به منظور بررسی اثر تنوع گیاهی و نوع منبع تغذیه ای بر تنوع و تراکم علفهای هرز و حشرات، کارایی مصرف نهاده ها ( نور، آب، عناصر غذایی) و عملکرد و خصوصیات کیفی چند گونه زراعی، آزمایشی به صورت کرتهای خردشده بر پایه طرح بلوکهای کامل تصادفی با سه تکرار در دو سال زراعی 1385-1384 و 1386-1385 در مزرعه تحقیقاتی دانشکده کشاورزی دانشگاه فردوسی مشهد به اجرا درآمد. تیمارهای مورد بررسی دو منبع کود دامی و...
In order to study the effects of different protein feeds on honey bees (Apis mellifera L), experiments were conducted in a completely randomized block design with 15 treatments and 4 replicates. The nutritional effects of different treatments on caged bees were studied through recording half-life time (50% mortality). Pollen substitutes were soybean flour, soybean meal, bread yeast, wheat glute...
Habitat disturbance affects numerous ecosystem components and processes, but its effect on continuous soybean system is less available. Soybean was seeded following six preceding crops, including grain soybean (Glycine max L. Merill.), wheat (Triticum aestivum L.), sugar beet (Beta vulgaris L.), tobacco (Nicotiana tabacum L.), corn (Zea mays L.) and hemp (Cannabis Satia L.), on a Mollisol ...
This study was performed to determine the optimum level of soybean meal diets for two banded sea bream for growth performance, nutrient utilization, body composition and serum biochemistry. Two banded seabream were fed five experimental diets which were formulated replace fish meal by soybean meal at 0, 20, 30, 40 and 50%. Up to 40% of dietary fish meal was successfully replaced with no growth...
In this study, the effects of replacing fish meal with soybean meal on growth performance, feed efficiency, body composition, fatty acid profile and gut lactic acid bacteria of beluga sturgeon, Huso huso. Nine diets were formulated (40% crude protein) in which soybean meal was replaced by fish meal at 0 (control), 40 and 80% supplemented and with three multi-enzyme level 0, 1 or 2 g/kg of Kemin...
Concerning the effects of increasing the species number on the maintenance of ecological stability and agricultural ecosystems sustainability, two field studies were conducted in 2002 and 2003 to evaluate the effects of plant population densities on soybean and sorghum intercropping at the Research Center, the Faculty of Agriculture, Tabriz University, Tabriz, Iran. Cultural pattern was an addi...

in order to evaluate intercropping of soybean (glycine max l. cv. jk) with sweet basil (ocimum basilicum l.) and borage (borago officinalis l.) with weed interference, an experiment was performed in randomized complete block design with 12 treatments and three replications at a field located 10 km of shirvan during year of 2011. the treatments were included 75% soybean: 25%sweet basil, 50%soybe...
This experiment was conducted to determine nitrogen fractions and ruminal dry matter and protein degradability of raw or heated (roasted or extruded) soybean seed. Samples were incubated for 2, 4, 8, 16, 24 and 48 h in the rumen of 4 cannulated Kurdish male lambs (50 ± 3 kg BW) . N itrogen fractions of samples were measured by chemical methods. Results showed that extruding decreased non-prot...
The purpose of this study was to evaluate the effect of different levels of oil and soybean meal and Canola meal separately and mixed on productive performance, rumination and digestibility of nutrients in Holstein dairy cows. This research was carried out in a completely randomized design on 35 Holstein dairy cattle with 7 treatments and 5 cows with an average weight of 650 ± 40 kg. Treatments...
