Abstract This study highlights the effect of drought and ambient temperature on performance and herbage quality of legume monocultures and grass-legume mixtures. In a field experiment, the total dry matter yield, seasonal pattern of dry matter yield distribution, content of crude protein and crude fibre of monocultures of red clover and alfalfa and grass-legume mixtures were investigated during two consecutive dry years (2011-2012). Alfalfa cultivars Kamila and Tereza grown as monocultures or as mixtures with Festulolium braunii (cultivar Achilles) outperformed the red clover cultivars Fresko and Veles and provided a well-balanced total and seasonal dry matter yield during both years. Across all experimental years, crude protein content was significantly higher at alfalfa monocultures and mixture when compared with clover monocultures (P < 0.05). However, considerable lower content of crude fibre at clover monocultures in comparison with alfalfa ones was found. Responses of nutritive parameters of both legume species to weather variables were different. Crude protein content in red clover was independent of rainfall and temperature. In contrast, the crude fibre content correlated with temperature whereby the alfalfa monocultures showed stronger correlations (P < 0.05) than red clover monocultures.

Annual Medicago

Foliar and stem diseases of annual Medicago spp. caused by Phoma medicaginis and Leptosphaerulina trifolii can not only reduce yield, but also affect herbage quality by inducing the production of the phytoestrogen coumestrol. To determine differences in host reaction to these pathogens, 33 cultivars and lines in 1993 and 10 cultivars in 1995 were evaluated in inoculated field tests. In the 1993 test, a number of genotypes with high levels of resistance to leaf and stem disease caused by P. medicaginis and to leaf disease caused by L. trifolii were identified. Genotypes with very high levels of resistance to stem disease caused by P. medicaginis were M. sphaerocarpos GRC5659.4.1 and SAD10069, M. murex GRC87.1, GRC707, and GRC708, M. truncatula Z771, and M. solerolii DZA3180.1, all of which had stem disease scores of ≤1.0 (scale 0 to 10) by the end of the growing season. The levels of coumestrol produced ranged from 114 to 1,230 ppm dry weight in stems across the genotypes, and the score for stem disease caused by P. medicaginis in the corresponding cultivars ranged from ≤0.8 to 8.9, respectively. The 1995 test confirmed the relative responses of nine cultivars (Caliph, Circle Valley, Cyprus, Harbinger AR, Zodiac, Paraggio, Santiago, Serena, and Orion) of annual Medicago spp. to leaf and stem disease caused by P. medicaginis and to stem disease caused by L. trifolii. Those with the lowest levels of coumestrol in the stems were M. solerolii DZA3180.1, M. truncatula Paraggio, and M. sphaerocarpos SAD10069, all with levels ≤130 ppm. The highest level was found in M. polymorpha SA4178 (1,230 ppm). M. littoralis Harbinger AR, Z286, Z298, and Z912, M. murex 89F16.1.1, M. orbicularis SA8460, and M. polymorpha SA4188, all had coumestrol levels of >600 ppm. For stem disease caused by P. medicaginis in particular, there was significant correlation of the level of disease with the level of coumestrol in stems at the end of the growing season. In contrast, for L. trifolii, there was significant negative correlation (leaf disease) or only a weak positive correlation (stem disease) with coumestrol in stems at the end of the growing season. Incorporation of these identified disease resistances into commercial cultivars offers a promising avenue not only as a long-term strategy for management of foliar diseases in annual Medicago spp., but also as a means of reducing phytoestrogen levels in commercial annual Medicago spp. pastures in order to minimize the adverse effects of phytoestrogens on fertility levels in sheep.

Herbage Quality

The effect of illumination at 100, 60 and 40% sunlight over 4 months on herbage quality was studied in the legume, Siratro, and the grass, green panic, grown in small plots in the field in pure and 50 : 50 mixture swards, defoliated every 4 (D4) or 8 (D8) weeks. Laminae and stems of defined ages were harvested periodically from the D8 treatment, and after 8 and 16 weeks the D4 and D8 canopies were sampled in 10-cm strata for analysis of dry matter digestibility (DMD). Shading to 60 and 40% sunlight decreased the DMD of the green panic and the mixed swards by up to 10-12 percentage units in the D8 treatment. The shade effect on DMD was smaller in the D4 treatment. Shading increased leaf bulk density in the upper strata of the grass and mixed swards. The shade effect on sward DMD was due to a decrease in DMD of lamina and stem of green panic and, in the lower canopy, also to a decrease in leaf : stem ratio of the grass. The lower DMD of green panic was associated with lower total soluble carbohydrate and higher lignin in the shaded tissues. The concurrent decrease in cell wall content of green panic under shade (as a balance to higher crude protein) indicates that shade must have greatly reduced the digestibility of the cell wall material. The chemical composition and DMD of Siratro was largely unaffected by shade.

SUMMARYHerbage availability, intake and nutritive value were recorded on swards of S. 59 red fescue (Festuca rvbra L.) and S. 23 perennial ryegrass (Lolium perenne L.), with and without S. 184 white clover (Trifolium repens L.), and correlated with animal performance. Intake of dry matter was similar on all treatments. Animal live-weight gains during 1969 were positively correlated with digestible organic matter intake (DOMI).Poor animal performance from red fescue swards in mid-summer was attributed to the rapid fall in digestibility at this time which affected DOMI.Differences between treatments in efficiency of conversion of DOMI into live-weight gains were observed. Superior conversion ratios in swards containing clover could not be related to any of the herbage quality measurements recorded.Better animal productivity from red fescue swards in early spring and in late autumn were related to the longer growing season of this grass.The merits and demerits of red fescue as a grass for hill conditions and the possibility of reducing its limitations by breeding are discussed.
