“…Starting with the beginning of flowering, harvesting time has a positive, significant influence at the 0.01 probability level (Table 1). The results of this study had similar trend with the conclusions of Alibés et al (1991), Layug et al (1996), , Pecetti et al (2001), Rimi et al (2010), Shroyer et al (1984), in studies conducted on the influence of the harvesting time on plant height.…”

Alternative use of alfalfa, for various purposes, including the production of biofuels or food supplement for human alimentation, is a study topic still in its early stages of research. Studying and understanding the biology of alfalfa and the factors with a major influence on it are very important activities. The productivity and quality of alfalfa are two indicators that help determine, in addition to economic value, the way in which alfalfa can be used. Evolution of alfalfa yield and quality depends on many factors, such as the growth stage of alfalfa plants at harvesting. It was observed over three years of vegetation the influence of alfalfa plant growth stage at harvest on plant height, leaves/stems ratio, production of leaves, stems and whole plant (DM -dry matter) per hectare and on quality indicators (CP -crude protein, NDF -neutral detergent fiber and ADFacid detergent fiber). The results showed that, with the advancement of phenological phases, from early bud stage to complete flowering, the total biomass output raised from 2.79 Mg·ha -1 to 4.60 Mg·ha -1, the neutral detergent fiber raised from 48.4-50.6% to 62.0-67.7%, while crude protein content decreased from 21.2-24.0% to 13.3-16.5%. The parameter values were correlated with alfalfa growth stage during the harvesting (significant at the 0.05 and 0.01 probability levels).

“…Neither red clover (T. pratense, L.) nor lucerne is considered suitable for repeated grazing, because of low persistence and slow recovery of damaged plant parts. However, recently selected varieties have shown some potential with respect to this aspect (Wang et al, 1996a;Pecetti et al, 2001). For lotus (Lotus corniculatus, L. and L. pedunculatus, Cav) or Caucasian (Kura) clover (T. ambiguum, M. Bieb), there have been few investigations in Europe on their suitability for grazing and there are several unsolved questions concerning the integration of these species into grassland systems (Abberton et al, 1998;Paul et al, 2002;Seguin et al, 2002).…”

In many parts of Europe there has been a net decline in the use of forage legumes since the 1980s, despite the reputed value of legumes for low-input livestock production systems. The political environment within which livestock farming in much of Europe operates (Common Agricultural Policy) is shifting the balance of economic advantage towards legumes and away from high usage of inorganic fertilizer. This has already been found for legume and grass-legume silages when compared with grass silages with a potential economic gain for farmers averaging 137 ha )1 , corresponding to an annual benefit for the European livestock farming sector of as much as 1300 million. Recent literature has shown that legume-based grazing systems have the ability to reduce environmental problems by increasing the efficiency of N use and by avoiding a high transient surplus of soil mineral N. From the perspective of livestock nutrition, when forage legumes contain moderate levels of secondary compounds, such as condensed tannins and flavonoids, they offer considerable advantages including increased efficiency of N utilization within the digestive tract, reduced incidence of bloat hazard and higher resilience to parasites.Nevertheless, these benefits are partially counterbalanced in both temperate and Mediterranean regions by difficulties in establishment, maintenance and management under grazing. To gain knowledge on mixed grass-legume pastures, further research is required on: (i) the development of sustainable systems of livestock production which can maintain sward persistence and agricultural production under environmental stress; (ii) increasing knowledge of soil-plant-animal relations for a wide range of leguminous species, and under different soil types and climatic situations; and (iii) the benefits for consumers of food produced from low-input livestock production systems.

“…1996), and this accounts for the low number of plants of this kind used in this investigation. Although an environmental effect on the observed differences in morphology among models could not be excluded, later evaluation of the replicated, clonal progenies of each selected genotype in a randomized complete block design (nine cuttings per plot) confirmed the presence of these differences for characters, such as plant height, vigour, and spreading ability, as well as forage quality features (Pecetti et al. 2001), thus corroborating an actual genetic bearing of the differentiation among morphological patterns.…”

Previous evidence indicates that differences in the concentration of underground organic reserves can drive the survival and growing ability of lucerne under cold and defoliation stresses. In order to provide the selection process with further information on compounds that may influence plant performance under grazing, we assessed variations in coldseason concentrations of nitrogen and carbon reserves on genotypes that had been identified for morphological features that possibly enhance grazing tolerance. The selected genotypes encompassed distinct morphological patterns (defined as ÔmodelsÕ) and different taxa within the Medicago sativa complex, as shown by different flower colours. Crown concentrations of reserves were determined on 90 genotypes, whereas root concentrations were measured on a subsample of 15 genotypes. Wide intergenotypic variation was observed for all reserve substances. Comparisons among models and among flower colour classes highlighted the high concentrations of crown carbohydrates and root and crown-soluble proteins of the model coded as ÔD1Õ, characterized by prostrate, rhizomatous habit and long dormancy, which largely corresponded to plants with yellow or variegated flowers, typical of ssp. falcata and · varia, respectively. There was a strong Ôflower colour · storage organÕ interaction for sugar concentration, and the results suggested a preferential compartment of sugars in the roots of purple-flowered genotypes that belonged to the ssp. sativa. A rank correlation analysis indicated a positive relationship between persistence after two years under grazing of half-sib progenies deriving from 19 genotypes out of the 90 and crown concentrations of carbohydrates of the 19 mother plants.
