Photosynthesis and Nutritive Value in Leaves of Three Warm-Season Grasses before and after Defoliation
Variation in the nutritive value of forages with maturity has been extensively researched (Buxton and MerForage yields are influenced by plant response to defoliation. We tens, 1995; Sollenberger and Cherney, 1995) and shifts examined the photosynthesis and nutritive value of first (first leaves) in proportions of leaf and stem during maturation of and third (third leaves) fully expanded leaves...
متن کاملNutritive Value Response of Native Warm-Season Forage Grasses to Harvest Intervals and Durations in Mixed Stands
Interest in management of native warm-season grasses for multiple uses is growing in southeastern USA. Forage quality response of early-succession mixed stands of big bluestem (BB, Andropogon gerardii), indiangrass (IG, Sorghastrum nutans), and little bluestem (SG, Schizachyrium scoparium) to harvest intervals (30-, 40-, 60-, 90 or 120-d) and durations (one or two years) were assessed in crop-f...
متن کاملInfluence of livestock grazing on C sequestration in semi-arid mixed-grass and short-grass rangelands.
We evaluated the effects of livestock grazing on C content of the plant-soil system (to 60 cm) of two semi-arid grasslands: a mixed-grass prairie (grazed 12 years), and a short-grass steppe (grazed 56 years). Grazing treatments included season-long grazing at heavy and light stocking rates, and non-grazed exclosures. Significantly higher soil C (0-30cm) was measured in grazed pastures compared ...

متن کاملYield and nutritive value of sainfoin (Onobrychis vicifolia Scop.) populations in different cuttings
Sainfoin (Onobrychis vicifolia Scop.) is one of the most important forage legumes cultivated as high quality forage. Fifty three species have been identified in this genus in Iran. A field experiment was conducted using randomized complete block design to compare yield and forage quality of 20 populations of sainfoin in Isfahan Agricultural and Natural Resources Center, Iran during 2013 – 2014....
