The productivity of a perennial lupin/cocksfoot mix was compared to that of lucerne in summer dry conditions at Lincoln University, Canterbury, New Zealand. The pastures were planted in December 2013 and rotationally grazed by ewe lambs in autumn 2014 (Year 1), and by ewe hoggets in spring-summer and ewe lambs in autumn of 2014/2015 (Year 2) and 2015/2016 (Year 3). For lupin/cocksfoot relative ...

The alfalfa weevil, Hypera postica (Gyllenhal), is a serious, yet sporadic defoliator of alfalfa, Medicago sativa L., in Nebraska. A 2-yr study was conducted in 2005 and 2006 to test for variation in degree-day requirements by location in eastern Nebraska. Sampling took place along a latitudinal gradient in three regions of eastern Nebraska. Three fields were sampled in each region during the 2...

in order to identification of allelopathic compounds and investigation of the effect of aerial part extract of orchard grass on germination and seedling growth of alfalfa an experiment conducted as completely randomized design with four replications at university of mohaghegh ardabili, iran. treatments were concentrations of orchard grass extracts including 0, 25, 50, 75, and 100%. radicle and ...

Birdsfoot trefoil is a high-quality forage recommended for irrigated perennial pastures, either in mixtures with grasses or in pure stands. In this bulletin we report on the forage nutritive value of pure stands of birdsfoot trefoil harvested at 6week intervals, and compare it to alfalfa harvested at the same intervals. We found that the digestibility of the two forages was similar, but that al...

Integrated pest management in alfalfa continues to be challenged by changes in the pests, alfalfa production system, environmental conditions, and other undetermined factors. Many of the underlying principles of integrated pest management (IPM) were developed from research conducted in the alfalfa system in the 1960-80’s. However, as indicated by challenges in controlling alfalfa weevil larvae ...

We conducted two experiments to determine the feeding value and effects on diet digestibilities, passage rates, and ruminal metabolism of wheat middlings (WM) fed as a replacement for either the concentrate or roughage components of finishing diets of steers. In Exp. 1, 120 medium-framed steers were blocked by weight and randomly allocated to one of six treatments of high-concentrate diets: con...

Transgenic alfalfa over-expressing a nodule-enhanced malate dehydrogenase (neMDH) cDNA and untransformed alfalfa plants were grown at the same field site and rhizosphere soils collected after 53 weeks of plant growth. These alfalfa lines differ in the amount and composition of root organic acids produced and exuded into the rhizosphere. Nucleotide sequencing of PCR-based 16S ribosomal DNA (rDNA...

Alfalfa is one of the most important legume forage crops in the world. In spite of its agronomic and nutritive advantages, alfalfa has some limitations in the usage of pasture forage and hay supplement. High rapid degradation of protein in alfalfa poses a risk of rumen bloat to ruminants which could cause huge economic losses for farmers. Coupled with the relatively high lignin content, which i...
