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...

Compatible rhizobia strains are essential for nodulation and biological nitrogen fixation (BNF) of hairy vetch (Vicia villosa Roth, HV). We evaluated how past HV cultivation affected nodulation and BNF across host genotypes. Five groups of similar HV genotypes were inoculated with soil dilutions from six paired fields, three with 10-year HV cultivation history (HV+) and three with no history (H...

this experiment was carried out to evaluations the allopathic foliar application of safflower)carthamus tintorius) aqueous extracts on growth and leaf cell membrane leakage of hairy vetech (vicia villosa).  the experimental arrangement was crd in four replications. results showed that by increasing the concentration of safflower extracts, shoot dry weight and peroxidase enzyme activity decrease...

in order to evaluate quantity and quality hairy vetch (vicia villosa l.) yield in the pure and mixed cropping with barley (hordeum vulgare l.) and triticale (triticosecale) the experiment was conducted at agricultural research station (khodabande) under dryland conditions during 2006 -2008. field experiments were arranged in a randomized complete blocks design with 9 treatments in four replicat...

Grass and legume mixtures work well, but there are no data on the mixed planting of desho grass (Pennisetum glaucifolium) Vicia species. A study was conducted to investigate whether forage dry matter yield (DMY) quality can be improved by growing species in with grass. The experimental layout followed a randomized complete block design four replications, where treatments consisted pure stands t...

This experiment was designed to evaluate the effects of the processing method of common vetch seed (CVS) (Vicia sativa) on laying performance, egg quality, metabolic parameters and liver histopatology during the peak production period in hens. Lohman layers, 46 wk of age in 6 replicate cages each containing 4 hens, were allocated randomly to one of four dietary treatments. Diets were control (C...
