in order to evaluate the influence of different tillage methods and autumn pea cultivars (arman, hashem, ilc-482) in first cultivation on corn forage yield (variety of single cross-704) in second cultivation, this research has been done. the experiment was conducted as split-plot in rcbd with the replication of 4 in tehran university from karaj in 2012. the main plots included different tillage...

Estimation of clover content of mixed swards is difficult in practise. We are currently in the processof developing several on-farm methods for clover content estimation. 1. Photos with various clovercontents are published in the Internet. 2. Yield samples with known area from several points of thefield are separated for clovers and grasses and weighted. 3. The clover content of...

To determine if host plant abundance determined the size of clover root weevil (CRW) Sitona obsoletus larval populations, a study was conducted over 4 years in plots sown in ryegrass (Lolium perenne) (cv. Nui) sown at either 6 or 30 kg/ha and white clover (Trifolium repens) sown at a uniform rate of 8 kg/ha. This provided a range of % white clover content to investigate CRW population establish...

in order to investigate the effects of biological and chemical phosphorous fertilizers and various proportions of maize and grass pea intercropping on yield and yield components of both crops, two experiments were conducted simultaneously in research farm of kerman university and commercial convention farm of bardsir-dashtkar in 2009-2010. the experimental design at two regions was randomized c...

Cross-reactive antigens of clover roots and Rhizobium trifolii were detected on their cell surfaces by tube agglutination, immunofluorescent, and radioimmunoassay techniques. Anti-clover root antiserum had a higher agglutinating titer with infective strains of R. trifolii than with noninfective strains. The root antiserum previously adsorbed with noninfective R. trifolii cells remained reactive...

in order to investigate the possibility of planting grass pea and common vetch crops after harvesting wheat and to evaluate the effects of  green manure of these crops on yield of potato-wheat in croprotation cycle, this research was carried out using a randomized complete block design with four replications during 2006-2010 at khair-abad research station, zanjan, iran. the treatments were eith...

BACKGROUND Due to symptoms and its complications, menopause influences the mental, psychological and physical health, social performance and familial relationships. Because of the undesirable side effects of hormone replacement therapy, tendency and desire toward alternative treatments in relieving menopausal symptoms have increased. Among the alternative therapies are herbs and among those, he...

the experiment was conducted in order to evaluate of competitive and economic indices in canola and pea intercropping at different rates of nitrogen fertilizer at shahrekord university research farm during 1390 - 1391. intercropping and sole cropping treatments (100% canola; 66% canola + 33% pea, 50% canola + 50% pea; 33% canola + 66% pea; 100% pea) were evaluated as the first factor and nitrog...

Substantial reproduction of Meloidogyne incognita on winter cover crops may lead to damaging populations in a subsequent cotton (Gossypium hirsutum) crop. The amount of population increase during the winter depends on soil temperature and the host status of the cover crop. Our objectives were to quantify M. incognita race 3 reproduction on rye (Secale cereale) and several leguminous cover crops...

The aim of this study was to assess the associative effects between orchardgrass () and red clover () silages as a model of preserved grass-legume mixture on voluntary intake parameters and digestive efficiency in sheep. Ten sheep were assigned to a repeated 5 × 5 Latin square design, in which 5 proportions of orchardgrass and red clover silages were tested (0:100, 25:75, 50:50, 75:25, and 0:10...
