The paper summarizes information on chromosome numbers (CNs) of the Grass species (Poaceae) in the flora of Russian Federation, obtained on the original material, most part - from the Russian Far East (RFE). In some species the CNs are known in Russia or in the world only from RFE, in some – from one locality or few, or from one subregion of RFE. The grass species in RFE often occur in mountain regions and near seacoasts; some species are endemics, some were studied near the limits of their geographical distribution areas. The diversity of CNs, the special features of the CNs distribution in some grass groups are discussed. The alien species are abundant in RFE, and their CNs are also involved in the study. For karyologically polymorphous species further studies are needed.

Studies were initiated in Wyoming to determine the potential of grass competition as an alternative to repetitive herbicide treatment or other cultural practices for control of Russian knapweed. An experiment was established to evaluate the effects of five grass species, including Russian wildrye cv. ‘Bozoisky.’ Picloram, applied to Russian knapweed during the first frost, reduced Russian knapweed from an average of 80.1% live canopy cover which equates to 0% control. Untreated, unseeded checks resulted in 83.9 and 81.1% control in tilled and nontilled treated plots, respectively. Grass cover increased in untreated seeded plots from an average of 11.3 and 8.2% in tilled and nontilled plots, respectively, to 65% in tilled and 66% in nontilled plots treated with clopyralid plus 2,4-D. Grass cover also increased 69.7% in tilled and 66% in nontilled plots treated with picloram. There was no significant difference between grass varieties when compared to percent Russian knapweed cover. Reductions to zero live canopy cover of Russian knapweed were obtained with a single application of picloram. Economic feasibility thresholds were obtained from four out of five varieties, including a significant difference provided by nontilled Russian wildrye treated with picloram.

Substantial Decline

The difference between cation and anion concentrations is an important property when assessing feed for dry dairy cows in order to avoid hypocalcaemia following calving. Dietary cation–anion difference (DCAD) is used to assess suitability of feed and predict the risk of milk fever; a value of –5 cmol(+)/kg dry matter (DM) or less is desirable. This work has examined the DCAD of 16 field-grown species found in pasture in southern Australia. The DCAD [cmol(+)/kg DM] at the flowering stage varied from 7 to 32 for grasses, 21 to 72 for legumes and 72 to 99 for dicot weeds. The average DCAD for legumes was 50 cmol(+)/kg DM, over 2-fold higher than the 20 cmol(+)/kg DM average for grasses. There was a substantial decline in DCAD of herbage as the season progressed. In a glasshouse experiment with five grass species in an acid soil, lime application increased yield and tended to lower the DCAD. Lime decreased uptake per unit root length of potassium and chlorine and increased uptake of calcium by phalaris and timothy. While DCAD is an important attribute of herbage for assessing its suitability for prepartum diets of dairy cows, the present data indicate that it would be prudent to also consider concentrations of calcium and other mineral nutrients in herbage, particularly when examining less familiar plant species or the effects of different cultural practices on the composition of herbage for such diets.

Bagi sesebuah negara yang mempunyai etnik pelbagai anutan kepercayaan dan perbezaan amalan budaya, dialog antara agama berperanan membetulkan semula kekaburan dalam kehidupan beragama dan berbudaya. Melalui peranan Saudara Baru, dialog antara agama mampu menjadi medan bagi menjelaskan kebenaran tentang agama Islam kepada masyarakat bukan Muslim dan pelaksanaan amalan budaya asal kepada Muslim asal. Objektif kajian ini ialah melihat pengalaman pelaksanaan dialog antara agama di Terengganu dan relevansi dalam kehidupan beragama di negara Brunei. Metode kajian ini menggunakan kajian dokumen yang menyentuh komuniti Cina Muslim di Terengganu dan Brunei. Pengalaman pelaksanaan dialog antara agama di Terengganu dan negara Brunei memperlihatkan dialog antara agama mampu membetulkan salah faham dan selanjutnya mengendurkan ketegangan hubungan antara agama dan budaya antara komuniti Saudara Baru, ahli keluarga bukan Muslim dan masyarakat Muslim asal. Biarpun begitu, adalah dicadangkan agar kajian yang menyentuh dialog antara agama perlu diperkukuhkan sebagai medium membina semula peradaban memandangkan penduduk di kedua-dua lokasi ini terdiri daripada berbilang etnik dan agama sedangkan pada masa yang sama masalah yang menyentuh hubungan antara agama sentiasa timbul. Abstract: For a country with diverse ethics of beliefs and cultural practices, interfaith dialogue plays a role to redefine ambiguity in religious and cultural life. Through the role of the New Muslim (Muslim Convert), interfaith dialogue can become a medium to explain the truth about Islam to the non-Muslims and the implementation of real cultural practices to the others Muslim. The objective of this study is to examine the experience of interfaith dialogue in Terengganu and in Brunei. The method of this study is being conducted in document research that related with the Muslim Chinese community in Terengganu and Brunei. In addition, interviews with people involved in the management of New Muslims also carried out. The experience of interfaith dialogue in Terengganu and Brunei shows that dialogue capable explains misunderstandings and further loosening the tension between religion and culture among New Muslims, non-Muslim family members and Muslim communities. However, it is recommended that studies on interfaith dialogue should be strengthened as a medium for rebuilding civilization as the residents of both locations are multi-ethnic and religious while at the same time the problem of interreligious persists.

Botanical composition of grasses is one of the most important indicators the biological value and quality of the obtained hay and pasture forage, the longevity of hayfi elds and pastures depend on. The issue of changing the botanical composition of agrophytocenoses is especially important in the context of global climate change, which in recent decades is also manifested in the territory of Ukraine, as it is possible to establish the most adapted species of legumes and cereals to adverse weather conditions and to identify eff ective technological methods of managing these processes for maximum conservation economically valuable species in the herbage. The purpose of the research is to establish the infl uence of diff erent ways of sowing of clover and alfalfa cereal crops agrophytocenoses on the formation of their botanical composition. Field studies have established diff erent eff ects of conventional in-line, cross-section and cross-sectional methods of sowing on the formation of botanical composition of grass mixtures of clover meadow (Trifolium pratense) varieties Sparta and Pavlyna with timothy meadow (Phleum pratense) and fenugreek multifl oral (Lolium multifl orum) and of agrophytocenoses of alfalfa of Sinyukha and Seraphima sowing varieties with reed fire (Festuca arundinacea Schreb) and middle wheatgrass (Elytrigia intermedia). For the average of four years of life of clover and alfalfa cereal crops agrophytocenoses, the highest proportion of legume component was observed with split-cross sowing – 51.6 % for Sparta, 53.1 % for Pavlyna, 60.3 % for Seraphima and 61.6 % for the Sinyukha variety. In the fourth year of life (the third year of use) of sowed leguminous-cereals agrophytocenoses, the preservation of the legume component was 14.6–15.5 % in clover-cereals grass mixtures with the Sparta variety and 16.0–16.8 % with the Pavlyna variety. In alfalfa grasslands, these indicators were 54.0–55.1 % with Seraphim and 55.0–56.2 % with Sinyukha. Among the studied varieties of clover meadow and alfalfa sowing proved better in the conditions of the Forest Steppe of western Pavlyna and Sinyukha. Cross-sectional and divided cross-sectional sowing of legumes and cereals mixtures proved to be better compared to conventional row crops in terms of conservation of economically valuable grass species. Key words: agrophytocenosis, botanical composition, clover meadow, alfalfa sowing, sowing methods.

New Cultivars

Some characteristics of seed quality, establishment rates, performance in mixtures and response to grazing management of 5 new pasture plants with potential in dryland are described. On a dry hill country site in the Wairarapa, the contribution of the sown grasses established in separate plots with clovers under rotational grazing was 'Grasslands Wana' cocksfoot 65%; 'Grasslands Maru' phalaris 23%; 'Grasslands Matua' prairie grass 22%; and 'Grasslands Roa' tall fescue 13% after 2 years. The other main grass species was resident perennial ryegrass which established from buried seed (ca. 240 plants/m*) and had a major impact on the establishment and growth of the sown grasses. On a seasonally dry Manawatu flat land soil 3 grazing managementsviz. set stocked all year (S); rotational all year (R); and combination (Cl (set stocked from lambing to drafting and rotational for the remainder of the year) were applied to mixtures of the new cultivars (except that 'Grasslands Apanui' cocksfoot replaced Wana) with ryegrass and white clover stocked at 20 sheep/ha. After 3 years the contribution of the new cultivars was negligible under S and ryegrass was dominant. The R pastures became cocksfoot dominant and Matua (in winter) and chicory (in summer) contributed more than in the S system. The C system produced the most evenly balanced species contribution with only Roa remaining at (5%. A sub-trial with cocksfoot cultivars demonstrated that Wana maintained better production and tiller density ~ll,000/m2 ) than Apanui (1000/m' ) under set stocking IS). Although some of the new cultivars will require specialised management procedures to fulfil their potential in dryland, the increasing and widespread use of Matua prairie grass in farming suggests that these techniques can be adopted in commercial agriculture provided good technical information is available in a management package when the cultivar is released.

Point Of Departure

From a remarkably innovative point of departure, Ben Highmore (University of Sussex) suggests that modernist literature and art were not the only cultural practices concerned with reclaiming the everyday and imbuing it with significance. At the same time, Roger Caillois was studying the spontaneous interactions involved in games such as hopscotch, while other small scale institutions such as the Pioneer Health Centre in Peckham, London attempted to reconcile systematic study and knowledge with the non-systematic exchanges in games and play. Highmore suggests that such experiments comprise a less-often recognised ‘modernist heritage’, and argues powerfully for their importance within early-twentieth century anthropology and the newly-emerged field of cultural studies.

The Way

Covering the period from 709 to 871, this chapter traces the initial conversion of Afghanistan from Zoroastrianism and Buddhism to Islam. Highlighting the differential developments in four regions of Afghanistan, it discusses the very earliest history of Afghan Islam both as a religion and as a political system in the form of a caliphate.  The chapter draws on under-utilized sources, such as fourth to eighth century Bactrian documents from Tukharistan and medieval Arabic and Persian histories of Balkh, Herat and Sistan. In so doing, it offers a paradigm shift in the way early Islam is understood by arguing that it did not arrive in Afghanistan as a finished product, but instead grew out of Afghanistan’s multi-religious context. Through fusions with Buddhism, Zoroastrianism, early Abrahamic traditions, and local cult practices, the Islam that resulted was less an Arab Islam that was imported wholesale than a patchwork of various cultural practices.
