nitric oxide (no) is a small molecule synthesized by most of mammalian cells with diverse biological activities including vasodilatation, host defense and wound healing. impaired wound healing is a common occurrence among diabetics and patients receiving glucocorticoid therapy. on the other hand the application of laser in biomedical area have been increased. thus, the current studies were desi...
Effects of different levels of nitrogen fertilizer and cutting time of forage on grain and forage yield of barley (Hordeum vulgare L.) Karoon cultivar was studied during 1995-1996 at Ramin Agricultural Research and Educational Center, University of Shahid Chamran, Ahwas, by using a split plot design in randomized complete block with 4 replications. Main plots were assigned to five levels of N...
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...
The effects of maturity of maize at harvest, level of inclusion and potential interactions on the performance, carcass composition, meat quality and potential concentrate-sparing effect when offered to finishing beef cattle were studied. Two maize silages were ensiled that had dry matter (DM) concentrations of 217 and 304 g/kg and starch concentrations of 55 and 258 g/kg DM, respectively. Grass...
Plant breeding researches is based on genetic diversity and evaluation of genetic diversity is also one of the most important steps in introduction of new cultivars. In this study, genetic diversity of 25 grass pea genotypes was studied based on randomized complete block design with three replicates in Khorramabad (Iran). Analysis of variance showed significant differences among genotypes for m...
The aim of the present investigation was to study the growth, yield and yield components of maize (Zea mays L.) single cross 704 under different levels of irrigation, plant density, and ethephon in southern Iran where this particular crop has not yet been studied in detail. A field experiment was performed in the 2004 5 growing season at the experimental farm of the College of Agriculture, Shir...
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...
Maize (Zea mays L.) production requires large amounts of nitrogen (N) thatdirectly affect production cost. Poultry litter can be used as an alternative source ofN. To optimize its use, poultry litter requires technical and economic feasibilityanalyses. Crop simulation models have proven to be efficient tools to support thistype of research. The objectives of this study were to determine yield a...
Sainfoin in believed as an important forage crop regarding its suitable agronomical characteristics and feeding livestock. Evaluation of general combining ability is a critical preliminary stage before selection of suitable parent and production of synthetic varieties. Thirty six sainfoin landraces which have been collected from different parts of Iran were grown in 2000 in a randomized complet...
Cynara cardunculus var. scolymus L. is a herbaceous perennial plant that could be drought tolerant once established after the first year. To evaluate the effects of water stress on growth parametersand forage quality of this plant, a field experiment was conducted using a randomized complete block design with three replications in Isfahan, Iran during 2013-2015. Treatments wer...
