ABSTRACT
Fodder cultivation and pasture improvement is a relatively new concept for Nepalese farmers. The trend of fodder cultivation and pasture land improvement is increasing. Many xotic pasture and fodder species have been introduced in Nepal.
Large quantity of improved pasture seeds have been imported by various agencies. Over 172 species and 371 cultivars are already tested at various farms. The most promising species in terms of dry matter production and seed production are found to be : legumes: berseem, vetch, stylo, white clove. Grasses: oat, teosinte, napier, molasses, perennial ryegrass, cocksfoot. The productivity of these grasses and legumes are recorded up to 18 times morethan the native grasses.

Introduction
Fodder cultivation and pasture improvement is a relatively new concept for Nepalese farmersin Nepal. Since the last decade, fodder crop cultivation has tremendously increased. It was reported that in 1990, approximately 1061 ha of cultivable land was brought under fodder cultivation. Similarly, a total of 4430 ha of community grazing lands especially at temperate region have been improved (DLS, 1992).
Nepal has a total of 1.7 million ha of natural grassland (LRMP, 1986). Most of these rangelands are situated in the mountains and Himal regions. These grazing lands are heavely grazed by livestock and wild animals as well. Due to century old traditional grazing practices, most of the accessible grazing areas and the forest lands are severely exploited. Increasing population of human as well as livestock have exerted excessive pressure onto the existing natural resources, resulting in overexploitation of natural resources such as land and forest. This has ultimately affected on the fragile ecosystem and environment. Denudation,desertification, loss of top soil, landslide, flooding have rechead a critical level.
These natural grasslands need renovation and improved management practices not only to solve the crucial feed deficit but also for environmental conservation.
Many exotic pasture and fodder species have been introduced in Nepal. Some of these species have been found promising for cultivation and renovation of the native pasturelands. These exotic species not only contribute to higher fodder production but also to control soil erosion and to improve soil fertility status.

Trend of Fodder Cultivation and Pasture Improvement
Fodder cultivation in true sense started from 1970’s in Nepal. The conventional belief that livestock thrives on natural vegetation and crop by-products are the major constraints for forage improvement.
The area under fodder crop cultivation and rangeland improvements are preseneted in the Table-1.

The are under fodder cultivation is 0.01 perecent of the total cultivated land. Similarly, only 0.04 perecent of the total rangelands have been improved so far. When compared to other countries, the land devoted for fodder cultivation is negligible. The developed countries have allocated a significant amount of land for fodder and pasture production. Even in the neighbouring country like India over 5 percent of the cultivated land is under fodder crop (Table-2).

Foddere and Pasture Development Activities
Fodder and pasture development programme has always been given low priority. Since 1980’s the government has started to pay proper attention to improve the fodder situation. Department of Livestock Services (DLS) has been implementing pasture and fodder development programmes through its various district level offices.
The sole institution for pasture and fodder development activity at district level is the Livestock Services, Department of Agriculture Development. Other agencies involved in pasture and fodder development are Nepal Agricultural Research Council (NARC), Pakhribas Agricultura Centre (PAC), Lumle Agricultural Centre (LAC), Institute of Agriculture and Animal Science (IAAS), Department of Forest (DoF), Department of Soil and Water Conservation (DSWC) etc. Many International Organisations such as FAO, Himalayan Pasture and Fodder Research Network RAS /79/121; High Altitude Pasture Development (NEP/85/007), Asian Development Bank, Livestock Development Project, USAID, and currently IFAD, Hills Leasehold Forestry and forage Development Project have contributed significantly to the fodder and pasture development activity.
Singificant amount of pasture seeds and large numbers of species/cultivars have been imported and tested for adaptability and production performance. Some of the species are localized and naturalized at the sites of introduction, for exaample, white clover in Kathmandu valley, Kikuyu in Jiri etc.

Importation of fodder/pasture seed:
As a part of fodder and pasture development program, a large quantity of fodder and pasture seeds were imported from overseas and distributed to the farmers. The recorded quantity of pasture and fodder seed procured are over 7.7 mt fom 1987-1992 by three projects alone viz. NEP/85/007, RAS/79/121 and ADb funded LDP (Table-3). The two projects NEP/85/007 and ADB/LDP have imported a total of 4118 kg and 3100 kg of seeds respectively mainly for the use of range seedings, whereas the seed imported by RAS/79/121 was 42.85 kgs mainly for research and demonstration purposes (Pande, 1993). Many other agencies like PAC, LAC, NGOs like SATA/HELVETAS,CARE Nepal imported seed in small amount.

Since 1940, over 162 species and 371 cultivars of grasses and legume species have been introduced in Nepal (Pande, 1993) (Table-4), the trend of introduction is being continued. Due to lack of proper doumentations and reporting, the performance of all introduced species/cultivars could not be recorded.

Opportunities and Performance of Exotic Species
Fodder production
Some of the exotic species have ability to produce large quanitity fodder of higher quality even under harsh conditions. These exotic species have long growing season and produce green fodder even in dy conditions when most of the local species dries out. The dry matter (DM) yield of the exotic species were found 3.1 mt DM/ha from Festuca arundinacea up to 13.4 mt DM/ha from Lolium multiflorum (Table-5). The native range species usually produces 3-4 mt DM/ha under ideal conditions. Compared to the native pasture species, there seems great potentiality to increase the fodder yield with these exotic species. These exotic species are also high in CP content (12-14%) compared to the native pasture species (9-9 percent).
Trifolium alexandrinum (Berseem) and Avena sative (Oat) are used as mono cultivated winter crop; Pennisetum purpureum (Napier), Stylosanthes spp (Stylo), Microptitium atropurpureum (Siratro), Melinis minutiflora (Molasses) and Setaria anceps (Setaria) are used to upgrade forage production of terrace risers and bunds.
Trofolum repens (White clover), Stylosanthes spp ( Stylo), Dactylis glomerata ( Cock’s foot) and Lolium perenne (Perennial rye-grass) are used for rangeland improvement. Stylosanthes spp, Desmodium spp (desmodium), Pueraria phaseoloides (Kudzu) and Melinis minutiflora have been used in agro-forestry and silvi-pastoral production systems.

Seed Production
The major limiting factor for the development of fodder and pasture production in Nepal is the availability of quality seed. Till now majority of required seed are imported from overseas. However, since the last decades i.e. 1980’s, seed production of fodder crop such as oat, berseem are quite popular and has shown potentiality to export to the neighbouring country. For example, during 1990, 500 kgs of oat seed and 300 kgs of berseem seed have already been exported to Bangladesh by Department of Livestock Services. Similarly, perennial pasture species like stylo and molasses grass have shown great potentilailty for seed production.
There seems a good potentility to promote pasture and fodder seed production in Nepal. The study conducted on fodder seed production revealed that different regions are suitable to produce different species of fodder and pasture seeds. The recorded seed yield from different species/cultivars at different sites are presented in Table-6.

Recommended Species and Cultivars for Different Regions
Nepal has a diversified types of climate. The climate ranges from tropical in the Terai region to the alpine in the high Himalayas. Within the region itself, there is a variation of micro climates. The germplasm introduced in Nepal have a wider ranges of species. Among the introduced species, some are annual and some are perennial. Furthermore, depending on the growing season these species are divided as summer and winter forage.
Based on the available information suitable species for the different regions are listed in Table-8

Major Species for Intensive Use
Out of the introduced species in Nepal, all potential species suitable for different agro-ecological zones may not be applicable to develop and recommend for the production of fodder at farmer level. The most potential and farmer’s preferred species should be developed as a pet species at the present level of available resources. The pet species are listed in Table-9.

1 Berseem Winter fodder for the cultivated lands throughout Terai and Siwaliks
2 Vetch Winter fodder for the cultivated lands throughout Terai and Hills
3 Stylo For silvipasture system on barren/steep lands throughout Terai and Hills up to 1200 m als
4 White clover Range seeding in Midhills and mountains from 1200-4000 m asl.
B Grasses
1 Oat Winter fodder for the cultivated lands throughout Nepal
2 Teosinte Summer fodder for cultivated lands throughout Terai and Hills
3 Napier Summer fodder on bunds, terrace and roadside throughout Terai and Midhills upto 1500 m asl
4 Molasses For silvipasture system as summer fodder on barren/step lands throughout hills from 500- 1500 m asl
5 Perennial Ryegrass Range seeding in mid hills and mountains from 1200-3500 m asl.
6 Cocksfoot Range seeding in midhills and mountains from 1200-3500 m asl.

Conclusion
Fodder is the most important and cheap source of livestock feed. By selecting appropriate species and cultivars the seasonality of fodder production could be overcome. Many exotic species have already started to give the positive results e.g. cultivation of oat and berseem in Terai and Hills. Similarly, introducing exotic species into the natural grazinglands and the afforestation sites could improve the productivity of fodder. To solve the acute fodder deficit situation prevailed in Nepal these introduced species could be a boon for Nepalese grassland farming. However, the importance of native species should not be ignored.
