Cutting Date Effects Of Yield And Quality Of Unimproved Kudzu (Pueraria Lobata (Willd.) Ohwi.), T H. Terrill, S Gelaye, S Mahotiere, E A. Amoah, S Miller, W R. Windham
IGC Proceedings (1997-2023)
Kudzu (Pueraria lobata (Willd.) Ohwi.), a vigorous, perennial warmseason legume, is considered a weed in the southern United States. It is tolerant of drought and low soil fertility and has potential as a low-input forage for livestock production. A field experiment tested effects of cutting date on yield and nutritive value of an unimproved stand of kudzu (10-15 yr old) in central Georgia. Yield measurements were made in June, July, September, and November, 1994, with forage samples taken to determine quality parameters. Soil fertility was unaffected by cutting treatment. Whole plant and leaf dry matter (DM) production and crude …

Dry Matter Production And Nutritive Value Of Forage Of Digitaria Eriantha Cv. Irene In Two Locations Of The Central Semi-Arid Region Of Argentina, C A. Frasinelli, H J. Petruzzi, J H. Veneciano, C M. Ferri, V V. Jouve, N P. Stritzler, O A. Terenti
IGC Proceedings (1997-2023)
The aim of this experiment was to compare dry matter (DM) production rates and nutritive value of a warm-season grass, Digitaria eriantha cv. Irene, in two locations of Central Argentina, Santa Rosa (SR) and Villa Mercedes (VM). The plants were established in two identical groups of plots, within a randomized block design. DM rates were calculated from serial, out of phase clippings, and in vitro dry matter digestibility (IVDMD) and crude protein (CP) content analyzed on subsamples. The study lasted for three consecutive growing seasons. Results showed that DM production rates were generally higher (P<0.05) in SR than in VM, but IVDMD and CP content showed no clear trends between both locations. DM production tended to lower from year 1 to 3, related to processes of N depletion from soils (VM) and diminishing rainfall (SR). It is concluded that D.eriantha is a very promising warm-season grass to Central Argentina. Data of nutritive value obtained in one location can be used in others, but results of DM production rates should be taken under the conditions where they will be used.
Separate Harvest Of Leaves From The Stems Of Lucerne Stands, L Schmidt
Separate Harvest Of Leaves From The Stems Of Lucerne Stands, L Schmidt
IGC Proceedings (1997-2023)
Lucerne leaves have significantly higher crude protein and lower crude fibre contents than the stems. The present methods for separating the leaves from the stems have serious deficiencies. Early harvesting, for example, weakens the lucerne stand, and sifting after artificial drying impairs quality. Above that, preparation of leaf protein concentrates is rather expensive. Field trials with a pronged cylinder which strips the leaves from the stems produced leaf yields of ž 80 % with a stem portion of £ 15 % (containing ž 26 % crude protein and £ 18 % crude fibre in the dry matter). Lucerne leaves can …

Spring Triticale Forage Yield And Nutritive Value As Affected By Location And Maturity In Wisconsin, Y. Newman, K. Jarek, P. Holman, M. Akins, E. Schreifer, R. Zogbaum
IGC Proceedings (1997-2023)
Spring triticale (X Triticosecale Wittm.) has a nutritional value that is like other spring cereal grain forages and presents a wide range in value and potential for ruminant feed (Emile et al. 2007). As varieties are improved, they may compete with oats as a spring forage source. A multi-location evaluation was conducted during 2021 in Wisconsin (Spooner, Marshfield and Lancaster) to evaluate spring triticale varieties harvested at two maturities (boot and mature stage) for yield and nutritive value. Treatments included six spring triticale varieties (AR-1, AR-2, AR-3, AR-4 and a local oat (WI-O) and triticale (WI-T) variety. Response variables measured …
