This study aimed to evaluate the performance, some carcass characteristics from feedlot lambs receiving sunflower crushed (SC) in the diet on partial replacement of soybean meal. The experimental design was randomized block with four levels of SC in the diet (0, 10, 20 and 30% of dry matter (DM)). There was a linear reduction of 0.02; 0.003; 0.003 and 0.17% for each percentage unit of added SC ...

to study the effect of strip intercropping pattern with cowpea and soybean on sorghum fodder yield an experiment was conducted at research farm of university of tehran (karaj) during 2005. the experiment was arranged in a randomized complete block design of four replications. the plant proportions included pure culture of sorghum (sss); cowpea (ccc) and soybean (ggg) each in 12 rows; vs differe...

in order to evaluation the different sowing date and different harvest time in intercropping of maize and legume plants on maize forage quality, a randomized complete block with three replications conducted in research field of university of sari agricultural sciences and natural resources in 2011. treatments were included three legume plants (soybean, fenugreek and cowpea) at two sowing time (...

potential for decreasing the amount of symbiotic N2 fixation. In contrast, Lory et al. (1992) reported that Although most of the N required by soybean [Glycine max (L.) topdressed manure addition to alfalfa (Medicago sativa L.) Merr.] is provided through the process of symbiotic N2 fixation, supplemental N using broiler litter may boost soybean grain yields. The efdid not affect N2 fixation. Ga...

Intercropping is a sustainable practice to achieve higher production with the aim to limit external inputs. A field experiment was conducted at the research farm of the Faculty of Agriculture, University of Maragheh, Maragheh, Iran, during 2016 growing seasons with ten treatments to evaluate the yield, analyze the competition and insect’s assemblages in sunflower (as main plant)/soybean (as com...

An 11-year field study was initiated in 1979 to monitor population development of Heterodera glycines. Fifty cysts of a race 5 population were introduced into plots in a field with no history of soybean production and that had been in sod for 20 years. Soybean cultivars either susceptible or resistant to H. glycines were grown either in monoculture or rotated with maize in a 2-year rotation. Du...

Crop simulation models are valuable research tools in agricultural decision making. In order to increase its general applicability, models need to be evaluated in diverse conditions. To achieve this, CROPGRO-Soybean model was evaluated on Vertic Inceptisols in a climatically variable semi-arid tropical condition. The model predicted reasonably the temporal changes in leaf area index, biomass an...

The use of glyphosate resistant soybean (GRS) cultivars has increased rapidly from their introduction in 1996 to over 50% of Wisconsin soybean acres in 1999. While much research has been conducted using conventional cultivars to measure the influence of row spacing and seeding rates on soybean growth and yield, little has been done with new GRS cultivars. It may be necessary and/or more profita...
