“…Caucasian bluestem had a crude protein level of 5.8% and was followed by the little bluestems and indiangrasses with averages of 5.5 and 4.8%. These warmseason grass crude protein values are similar to those that were found by other investigators (3,7,20).…”

“…Several studies in the Great Plains have shown that P fertilizer increased yields and forage P concentrations of warm-season grasses (7,10,11,16). In Pennsylvania, Griffin 3 found that without applied N, P fertilization increased P concentration in the leaves and stems of switchgrass (Panicum virgatum L.) only slightly and had little effect on yield.…”

Millions of hectares of pasture in the Northeast have low available soil P levels. Introducing forage species that produce well on these soils could increase forage production with minimum economic input. The objective of this study was to compare the performance of warm and cool‐season grasses under low or high available P. Several warm and cool‐season forage grasses were grown on a Berks shaly silt loam soil (Typic Dystrochrept; fine, loamy, skeletal, mesic), low in native available P (5 ppm Bray and Kurtz #1 extractable P), with and without added P. The warm‐season grasses included two Old World bluestems, ‘Caucasian’ Bothriochloa caucasica (Trin.), C. E. Hubb. and “B”‐strain, B. intermedia (R. Br.) A. Camus; three big bluestem cultivars, Andropogon gerardi Vitman; three little bluestem cultivars, Schizachyrium scoparium, Michx.; six switchgrass cultivars, Panicum virgatum L.; and two indiangrass cultivars, Sorghastrum nutans (L.) Nash. The cool‐season grasses were Ky 31 tall fescue, Festuca arundinacea Schreb., ‘Pennlate’ orchardgrass, Dactylis glomerata L., and ‘Tioga’ deertongue grass, Dichanthelium clandestinum (L.) Gould. Yields of most warm‐season grasses nearly doubled from 1977 to 1978, whereas yields of the cool‐season grasses decreased. Forage yields and P concentrations of all cultivars generally were greater with applied P both years. At the low P level, warm‐season grass yields in the second year were up to three times higher than yields of cool‐season grasses, whereas P concentrations in forage of cool‐season grasses were twice those of warm‐season grasses: The warmseason grasses, Ky 729 and ‘Blackwell’ switchgrass, Ky 2 Caucasian and B‐strain Old World bluestems, and NJ 1617‐72 indiangrass absorbed more total P than all other cultivars. Warm‐season grasses had relatively low crude protein and IVDMD levels, ranging from 4.7 to 8.5% and 34.0 to 52.3%, respectively. Of the warm‐season grasses, Old World bluestems, Caucasian and B‐strain, had the highest IVDMD values, 52.2 and 51.2%. The cool‐season grasses had an average crude protein level of 14.6% and IVDMD value of 59.4%, respectively. The two Old World bluestems, Ky 729 and Blackwell switchgrasses, and NJ 1617‐72 indiangrass appear to have the highest potential to produce forage on soils with low levels of available P.

“…Phosphorus content of forage decreases with maturity (Fraps and Fudge, 1945;Lampkin et al, 1961), and there is a positive correlation between crude protein and phosphorus content in plants (Hemingway, 1967). Shin (1976) summarized that phosphorus supplementation of diets for ruminant animals The rate of disappearance from rumen is a function of both rate of pa~sage and particle size (Mertens, 1973).…”
