Atriplex species/cultivars [Atriplex nummularia, A. canescens (Santa Rita) and A. canescens (Field Reserve 1)] were compared in terms of chemical composition and in vitro digestibility. The plant material was sampled at different seasons (autumn and winter) and from different sites (Hatfield in the Gauteng Province and Mier and Lovedale, both in the Northern Cape Province) and were analysed for crude protein (CP), neutral detergent fibre (NDF) and in vitro digestibility (IVOMD). The CP and IVOMD of the leaves were higher than the stem for the Atriplex species. Leaf percentage for the autumn samples was not affected by species at Hatfield and Mier, but A. canescens (Field Reserve 1) had lower leaf percentage at Lovedale as well as for winter samples at Hatfield. At Lovedale, however, A. nummularia had the highest leaf : stem ratio compared to A. canescens (Santa Rita) and A. canescens (Field Reserve 1). Atriplex nummularia had a higher CP concentration than A. canescens (Field Reserve 1) and A. canescens (Santa Rita) at both Mier and Lovedale, but species/cultivar had no effect on CP concentration at Hatfield. Autumn samples had a higher CP concentration than winter samples at both Mier and Lovedale, but season had no effect on the N concentration at Hatfield. Atriplex nummularia had a lower NDF and higher IVOMD concentration compared to A. canescens (Santa Rita) and A. canescens (Field Reserve 1). Autumn samples were less fibrous and more digestible than winter samples. Atriplex nummularia seems to be better in terms of its nutritive value compared to A. canescens (Santa Rita) and A. canescens (Field Reserve 1), with better quality forage in autumn than winter. ________________________________________________________________________________

“…Planting halophytes is often the only opportunity to produce forage for livestock. A. nummularia is already used as a forage crop in several countries (Watson, 1990). The yield of such plantation could be enhanced by mycorrhizal inoculation, considering the mycorrhizal dependency of this plant.…”

“…Some physiological activity has been measured in field condition under plant moisture potentials of -8 to -13 MPa in A. confertifofia, A. obovata and A. nuttafii [Caldwell, 1974]. About 50% of the above ground production is forage, but this may considerably vary with the type of management which is applied [Le Hou6rou, 1983Watson, 1990Watson, , 1991. Hygrohalophytes have no tolerance to water stress in their native environment, they grow on permanently wet soils with a shallow water and productivity of these species is always poor on sandy soils and moderate on clay, under rainfed conditions.…”

“…These experiments were carried out with A. nummularia, A. lentiformis, A. barclayana and A. halimus subsp, halimus. But, usually, yields are much higher with irrigation waters of ¼ to ½ of seawater strength [Pasternak et al, 1990;O'Leary, 1988;Watson, 1990;Watson et al, 1987;O'Leary, 1985, 1986]; As a matter of fact with water concentration of 15% sea-water (7.5 mS cm -1 EC) yields are about double those attained with full strength sea-water [Pasternak et al, 1990;Watson, 1990].

The role of saltbushes (Atriplex spp.) in arid land rehabilitation in the Mediterranean Basin: a review

1992

View full text Add to dashboard Cite

Arid lands in the Mediterranean Basin harbour populations of saltbushes over substantial areas. These have been grazed for centuries and often cleared. There are also some 100,000 hectares of artificially established saltbushes, both native and exotic; they include no more than half a dozen species, when large scale plantations are concerned. Another dozen of exotic species, introduced from Australia, Southern and Northern America, have successfully undergone field trials and could be used on a large scale in a near future. The present paper attempts to review the current state of knowledge on Atriplex spp. in the Mediterranean Basin as a means of Arid Land rehabilitation at a time where huge areas in the region have undergone processes of severe degradation or have been subjected to desertization, particularly over the past four decades. In spite of a number of constraints in their establishment, management and utilization, the plantation of Atriplex spp. appears as one of the best way, if not the best one, to rehabilitate desertized areas and restore them to production, under the present state of knowledge on arid land rehabilitation. They, in particular, are amenable to inclusion into new, man-made agro-sylvo-pastoral systems of production well adapted to arid lands and to the needs of their populations.
