2. Descrição da abordagem de GST
2.1 Descrição curta da abordagem
Green manure-It is a way of adding nutrients and organic matters to soil by incorporating green manure plants which include both leguminous or non-leguminous plants. Sesbania, also known as Dhaincha, i.e. a diverse and versatile genus belonging to the family Fabaceae,which is soft,woody,annual or short lived perennial;primarily used as green manure between rice crops or as an intercrop in transplanted rice.
2.2 Descrição detalhada da abordagem
Descrição detalhada da abordagem:
Aims / objectives: -Leguminous green plants like Sesbania can fix atmospheric nitrogen in the form that plant can use.
-It helps to improve the soil structure as incorporating it into the soil adds organic matterr (biomass).
-The Sesbania species has high water-logging tolerance which prevents the crop from losing its nutrient content.
Methods: In nepal,institutions like NARC and research programs like Rice Research program has actively promoted Sesbania species. Dr. Bhola man singh basnet of Nepal Agriculture Research council(NARC),khumaltar has extensively carried out his research on green manure using Sesbania, which is called locally as Dhaincha.
The Hardinath Agriculture Farm in Dhanusha,now National Rice Research Program, practiced Sesbania cannabina, dhaincha as pre-rice manure annually in 20 ha for more than 20 years.
Green manure technique is an indigenous practice mainly in the foothills, middle mountains region and central terai of nepal-dhanusha,parsa,bara and Rautahat district.
Stages of implementation: Sesbania is sown before rice is planted.Sow the Sesbania seed densly and lightly cover the seed with soil.Sesbania will grow faster if the soil is kept moist.After 4-6 weeks sesbania will be 18-36 inches tall at ground level and plough in as the paddy are prepared for planting rice.
Seed production process;
Transplant a few of the largest,thickest,healthiest plant into the edges of paddy space at 2 metre intervals along the terrace edges.Seed will be ready after 6 -7 months.This can be used as seed for green manure next year.
Role of stakeholders: Government;
-Institutional roles; NARC, HAF -DDC-Municipality-VDC
Private sectors;
-Desigining policies.
Other important information: -Sesbania species can be grown even under adverse conditions of drought,waterlogging,salinity,etc.
-optimum time of Daincha seed production is the middle of March until the end of May .
-Experiment conducted at several research stataions showed that green manureing with dhaincha in rice increased the grain yields by about 20-25 percent(Pre rice green manure-a success story,B.H.S Basnet,NARC)

×2.7 Tipo de abordagem
- Tradicional/Indígena
2.8 Principais metas/objetivos da abordagem
The Approach focused mainly on SLM with other activities (Sesbania species increases nutrient content of the soil,due to its water logging tolerance and also increases the fertility,biomass production in the fields as well as nitrogen content of the soil by fixing large amount of Nitrogen.)
-Increase the nutrient in the soil due to its water logging tolerance and thus increases the fertility and productivity.
-Also reduce the need of artificial fertilizers
The SLM Approach addressed the following problems: Low knowledge about the green manuring among people because of which they were lured towards more use of particles and fertilizers.
Lack of improved seeds of green manure(plants).
2.9 Condição que propiciam ou inibem a implementação de tecnologia/tecnologias aplicada(s) segundo a abordagem
Disponibilidade/acesso a recursos e serviços financeiros
- Inibitivo
-Improved and large seeds of green manure are costly.
-This can be reduced if we can make these seed locally available at subsidized rate.
Treatment through the SLM Approach:
Quadro jurídico (posse de terra, direitos de uso da terra e da água)
- Propício
The existing land ownership, land use rights / water rights moderately helped the approach implementation: There was a bit hindrance.Seed cultivation requires both land use and irrigation system.
Conhecimento sobre GST, acesso a suporte técnico
- Inibitivo
-People were found unaware of the proper and new techniques of manuring.
Treatment through the SLM Approach: -Provide necessary information and conduct programs at local/regional level.
Outro
- Inibitivo
The species shows better growth and higher biomass yield in the sandy clay than in heavy clay soil.
Treatment through the SLM Approach: The areas with sandy clay loam should be identified if we are to except a high crop yield.

3.4 Decisão sobre a seleção de tecnologia/tecnologias de GST
Especifique quem decidiu sobre a seleção de tecnologia/tecnologias a serem implementadas:
- Principalmente usuários da terra, apoiados por especialistas em GST
Explique:
Green manuring using Dhaincha is an indigenous practice which is currently supported and motivated by many institutions.
Decisions on the method of implementing the SLM Technology were made by by land users* alone (self-initiative / bottom-up). Due to the dissatisfaction by the use of the fertilizers(artifical) land users themselves initiated the approach for better production.

6.4 Pontos fortes/vantagens da abordagem
Pontos fortes/vantagens/oportunidades na visão do usuário da terra |
---|
-if some species of sesbina like Sesbania cannabina are established as an intercrop in rice. -During short Day season,vegetative growth of the plant is reduced due to early flowering. -Many Sesbania species are being over ploited. -Improved seeds of sesbian sp, are costly and this technique requires a lot of labour work, people are in more favour of artificial chemical fertilizers. (How to sustain/ enhance this strength: -it can be suppressed by the rice if sown 30-60 days after crop. -These sp. should be sowed in the middle of March to end of vegetables growth. -Attention must be given to the conservation and proper utilization of these important plant species. -Government /local bodies should make it available at cheaper rate and encourage people to revive interest in green manures.) |
Pontos fortes/vantagens/oportunidades na visão do/a compilador/a ou de outra pessoa capacitada |
