Alfalfa forage yield, milk yield, and nutritive value under intensive cutting

چکیده
Forage yield, nutritive value, and stand persistence are key metrics in alfalfa (Medicago sativa L.) management. The combination of cultivar improvement, longer growing seasons the Midwest, trends shorter rotations offer opportunity to reevaluate effects increasing cutting frequency (CF) on these metrics. We evaluated forage milk production, eight entries with fall dormancy (FD) ranging from two (FD2) five (FD5) under CF four (CF4), (CF5), or six (CF6) annual cuts during production years environments upper midwestern United States. Nutritive value kg–1 increased differed among entries. Cutting entry interactively influenced yield ha–1 yet optimal depended environment. At one environment, CF4 CF5 CF6 caused a 5 29% decrease ha–1, respectively. another had about 16% greater than CF6. reduced 3rd-year density especially severe for some Alfalfa FD was not correlated persistence, but an FD5 consistently those greatest at These results suggest that intensifying harvests per season cultivars can boost without negative environments.

Influence of Different Seeding Dates on Fenugreek (Trigonella foenum-graecum L.) Forage Yield and Nutritive Value
Fenugreek (Trigonella foenum-graecum L.) is used as medicinal plant in many Asian countries and has been reported to have forage quality similar to alfalfa. Fenugreek is an annual crop and may have the potential to diversify forage production systems in the central High Plains. This study evaluated forage dry matter (DM) production and the nutritive value of three fenugreek cultivars as influen...

Influence of Rhizosphere Ionic Strength on Mineral Composition, Dry Matter Yield and Nutritive Value of Forage Chicory
Animal manure and urine deposition can cause localized patches of high ionic strength (IS) soil in pastures, influencing plant production, nutritive value and sward composition. Chicory (Cichorium intybus L.) appears to thrive in high-nutrient input situations, but no information is available on chicory response to increasing IS. In a greenhouse experiment, we evaluated the effect of rhizospher...
متن کاملQTL mapping of forage yield and forage yield component traits in Sorghum bicolor x S. sudanense.
The sorghum-sudangrass hybrid (Sorghum bicolor x S. sudanense) is an important forage crop. However, little is known about the genetic mechanisms related to forage yield and the 4 forage yield component traits in this forage crop. In this study, a linkage map was constructed with 124 assigned SSR markers using an F2 mapping population derived from the crossing of sorghum Tx623A and sudangrass S...
