The genetic diversity of 19 bitter vetch landraces (Vicia ervilia L.) from four provinces (East Azerbaijan, West Azerbaijan, Ardabil and Zanjan) of Iran was evaluated using 18 pairs of SSR primers. The extracted genomic DNA was amplified with eight pair primers and PCR products were separated on DNA sequencing gels. In this research, eight pair of SSR primers detected a total of 27 alleles...
تأثیر آبیاری تکمیلی و تیمار پیش جوانهزنی بذر بر صفات کیفی، عملکرد علوفه تر و خشک ماشک رقم دیم مراغه
To evaluate the effect of supplemental irrigation and seed priming on yield and some quantity and quality characteristics of vetch (Vicia dasycarpa) rainfed maragheh cultivar, an experiment was carried out at the Research Farm of Faculty of Agriculture, University of Urmia, West Azarbaijan province, Iran, during 2011. The experiment was laid out using split-plot, based on Randomized Complete Bl...
Nod factors secreted by Rhizobium leguminosarum bv. viciae induce root hair deformation, involving a reinitiation of tip growth, and the formation of nodule primordia in Vicia sativa (vetch). Ethylene is a potent inhibitor of cortical cell division, an effect that can be counteracted by applying silver ions (Ag+) or aminoethoxy-vinylglycine (AVG). In contrast to the inhibitory effect on cortica...
A 10-year-long field trial (between 2001 and 2010) was conducted to investigate the effect of paddy-upland rotation on rice yield, soil properties, and bacteria community diversity. Six types of paddy-upland crop rotations were evaluated: rice-fallow (control; CK), rice-rye grass (RR), rice-potato with rice straw mulches (RP), rice-rapeseed with straw incorporated into soil at flowering (ROF), ...
A 2 × 2 factorial experiment was carried out to evaluate the effect of herbage or concentrate feeding system and tannin addition to diet on skatole and indole in ruminal fluid and adipose tissue and meat sensory properties. Twenty-eight male lambs aged 45 days were randomly assigned to one of two feeding systems (vetch green herbage or concentrates, n = 14) and within feeding system to one supp...
This study explores the effect of phosphorus (P) fractions, under P addition or not, based on a common vetch-rape model cropping system in alkaline soil. A two year field experiment was conducted at Tuzuo Banner modern agricultural Park Inner Mongolia, China. Two levels, including P0 (no fertilizer) and P45 (45 kg·ha?1 P), were performed vetch rape either grown alone intercropped. We analyzed c...
Field experiments at Oakes, ND, USA in 2010 and Carrington, ND, USA in 2011 were conducted to evaluate the potential for cover crops grown in the Northern Great Plains, USA in order to reduce weed emergence and density in irrigated potatoes. Treatments included five cover crop treatments and three cover crop termination treatments. Termination of cover crops was done with glyphosate, disk-till,...
Nematicides are used to control a wide variety of nematodes on many crops; unfortunately, oftentimes the control they provide is erratic. This erratic behavior is not always predictable and has been associated with chemical, physical, and biological degradation of nematicides. Their accelerated degradation is an agricultural problem that has been observed in crop monocultures and in other crop ...
background and objectives: suitable tillage methods and planting cover crops are such factors in sustainable agricultural systems, which play an important role in the sustainability of agricultural production systems. minimum and no-tillage systems methods that leave instead of usually more than 30 percent of crop residue on the soil surface, are used to reduce soil erosion, improve soil physic...
Producers are interested in tactics for managing crop residues when growing corn after spring wheat. We compared five systems of managing spring wheat residues: conventional tillage, no-till, strip-till, cover crop (hairy vetch) with no-till, and cover crop with strip-till following spring wheat. Conventional tillage consisted of chisel plowing and disking, whereas strip-till consisted of tilli...
