red clover (trifolium pretense) has wide adaptability to different soil and climatic conditions, and suitable digestibility of forage compared to the other clover species. new red clover cultivar, nasim, was primarily selected from clover germplasm received from food and agriculture organization (fao), the united nations, in seed and plant improvement institute, karaj, iran. agronomic and yield...

modification of natural polymers like protein by graft co-polymerization is an important method to incorporate the desired properties into the backbone. soy protein concentrate (spc) was grafted with ethylmethacrylate (ema) using ascorbic acid /potassium persulphate as redox initiator system under pressure. different reaction parameters such as reaction time, reaction pressure, solvent amount, ...

Strong benefits of species diversity have been demonstrated in mixed cropping on rangelands. In order to determine the best composition of mixed cropping of alfalfa (Medicago sativa) with three cool season grass species (Agropyron elongatum, Agropyron desertorum and Festuca arundinacea), on yield and quality traits, an experiment was conducted during two years (2009 and 2010) in Bojnourd, Iran....

in order to evaluate forage quality in intercropping, two field experiments were carried out based on randomized complete block design with three replications at the agricultural research station, faculty of agriculture, university of tabriz, iran, in 2005-2006 and 2006-2007 growing seasons. two maize (zea mays l.) hybrids (sc704, sc301), vetch (vicia villosa), bitter vetch (vicia ervilia), ber...

mix cropping of alfalfa (medicago sativa) and annual ryegrass (lolium rigidum) may improve forage production in the rangeland and field conditions, especially in spring after the establishment year. in this study, the effects of different sowing rates of alfalfa and annual ryegrass seeds in the replacement and additive series of mix cropping were evaluated on forage yield in first year after th...

kochia is a halophyte plant and is a good source of forage for livestock under saline irrigation. in order to investigate the salinity effect on morphological and forage characteristics of kochia, an experiment was conducted. three saline waters (5.2, 10.5 and 23.1 ds m-1) and three kochia ecotypes (birjand, borujerd and sabzevar) were allocated as main and sub plots, respectively, in a split p...

introduction amaranth, genus amaranthus, belongs to the amaranthaceae family and includes more than 60 species (28). amaranth forage, is distinguished by high yield performance of up to 70 t/ha (30). plant maturity was found to affect neutral detergent fiber (ndf), acid detergent fiber (adf), lignin, cp and nitrate content of amaranth forage (27). several studies (21, 27, 29) have shown that the ...
