“…and Russia (8,12).' Seveial worker; (6, 7) have shown that alfalfa should be cut only after it has been given an opportunity to-stole a maximum amount of fooh reserves. Fall cutting should be regulated so that food reserves are not depleted prior to hardening of the Plants in PrePalatlon for the rigors of the winter season.…”

“…Root starch is thought to be an important source of carbon necessary for winter survival and initiation of growth in spring (8,9,16). It may also serve as an important source of carbon used to support shoot regrowth after defoliation (12,25,26).…”

The objective of this study was to examine the composition and branch chain lengths of alfalfa (Medicago sativa L.) The 12-KI absorbance properties of the low molecular weight starches from roots of the low starch genotype indicated that some branching may be present. The distribution of chain lengths from amylopectin did not change during starch degradation and reaccumulation for the high starch genotype. In the low starch genotype, the proportion of low molecular weight branches having a degree of polymerization between 1 and 30 was decreased at the very low starch concentrations observed on the 14th day of regrowth. Higher concentrations and/or quantities of starch in roots of the high starch genotype were not associated with greater rate of herbage regrowth, when compared to the low starch genotype.

“…On average over the cuttings in 2014, planting alfalfa with annual ryegrass had significantly lower crude protein contents, higher acid detergent fiber and neutral detergent fiber contents than other cover crop treatments. Nutritive values of alfalfa are generally affected by stage of maturity, cutting frequency, and harvest management (Brink and Marten, 1989;Brink et al, 2010;Kallenbach et al, 2002;Kust and Smith, 1961;Moyer et al, 1999) but nutritive values of alfalfa were also affected by cover crop tested in this study. It's not certain why alfalfa planted with annual ryegrass had the lowest nutritive values as compared to other cover crop treatments.…”

The objective of this study was to evaluate the effect of planting alfalfa (Medicago sativa L.) with-and without cover crops on forage dry matter yield and nutritive values of alfalfa in Kansas, USA. In the first production year 2014, dry matter yield of mono-culture alfalfa appears to be compatible or even higher than planting with certain species of winter annual forages as a cover crop. Alfalfa planted with a combination of four different multi-species winter annual forages such as oats (Avena sativa L.), oilseed radish (Raphanus sativus L.), annual ryegrass (Lolium multiflorum L.), and turnip (Brassica rapa L.) had the highest dry matter yield of alfalfa in 2014. Dry matter yield of alfalfa in 2 nd production year 2015 was similar to alfalfa + oats and alfalfa + oats + oilseed radish + annual ryegrass + turnip or significantly higher than alfalfa planted with annual ryegrass, oilseed radish, and turnip together. Based on two year of data in 2014 and 2015, the highest alfalfa yield occurred when alfalfa was planted with a combination of oats, oilseed radish, annual ryegrass, and turnip. The lowest dry matter yield of alfalfa occurred when alfalfa was planted with annual ryegrass. No significant differences in crude protein (CP), acid detergent fiber (ADF), and neutral detergent fiber (NDF) were found when comparing alfalfa monoculture with alfalfa + oats, alfalfa + oilseed radish, alfalfa + oats + oilseed radish + annual ryegrass + turnip, and alfalfa + turnip treatments. When considering both dry matter and nutritive values of alfalfa, planting alfalfa with cover crops appears to be compatible or better practice than planting alfalfa monoculture.
