agroforestry is one the aspects of sustainable agriculture in which multiple cropping of perennial trees in mixture with crops guarantees the environmental, economical and social sustainability in rural communities. high demands for forage in northern provinces of iran lead to agroforestry in citrus orchards as a potential mean for forage production through agroforestry systems. this research w...

R7 stage (one seed pod at mature color; 50% of leaves yellow) produced forage that was similar in quality to Tall forage soybean [Glycine max (L.) Merr.] cultivars in maturity alfalfa harvested at early bloom. When soybean was groups V, VI, and VII have been developed to supply forage. Our objective was to determine the effect of harvest date and row spacing grown as an intercrop with corn, the...

Diets with low forage concentration may depress feed intake and average daily gain, while diets with high forage concentration may limit feed intake due to rumen filling. Adequate forage level may range from 7% to 14% in ration for feedlot lambs, depending on forage source and ingredient composition. Small amounts of good quality forage may improve growth performance of sheep in the first stage...

Fifty-six mature Polypay ewes were used in two experiments to examine the effects of feeding a high-grain diet at a restricted intake on milk production and composition, lamb performance and out-of-season breeding. Ewes were fed either a high-grain diet (85% concentrate and 15% forage) or a high-forage diet. The high-forage diets were 68% forage and 32% concentrate in Experiment 1 and 80% forag...

sainfoin (onobrychis sativa), a forage legume, is worth attention because of its production and superior quality among pasture and hay forage crops in iran. sainfoin forage yield may be reduced by different levels of salinity. increasing forage yield in saline environments through plant breeding could partially compensate for this shortcoming if sufficient genetic diversity and heritability be ...

In many studies, topographic factors have been considered as an important factor in establishing the vegetation in different ecosystems. So, it affects vegetation composition and diversity by influencing soil moisture, fertility and soil depth. The aim of this research was to investigate the effects of slope, elevation and geographical aspects on species growth, forage production and vegetation...

The objectives of the current study were to determine the amounts of aboveand below-ground plant biomass production, P uptake by forage, and P concentration of cool-season grass forage as influenced by management and season. Five forage management treatments were evaluated over 3 years in smooth bromegrass (Bromus inermis Leyss) pastures. Management practices were: ungrazed (U), hay harvest/fal...

This experiment was conducted to determine the effects of nitrogen and phosphorus fertilizers on nutritive value of safflower forage and silage by in situ and in vitro methods. The safflower forage was harvested at flowering stage, chopped to 3-5 cm particles and then ensiled in the laboratory silos for 60 days. The experimental treatments included: 1. Unfertilized forage (control), 2. Phosphor...

Forage is included in beef cattle growing or finishing diets for several reasons. Nutritionally, forage provides protein, vitamins and minerals. When included as a minor component of high grain finishing diets, forage may increase feed intake and reduce nutritional disorders due to increased salivation, rumination and passage rate. Manipulating dietary moisture content through inclusion of dry ...
