2. Description de l'Approche de GDT

2.1 Courte description de l'Approche

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 Description détaillée de l'Approche

Description détaillée de l'Approche:

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 Type d'Approche

  • traditionnel/ autochtone

2.8 Principaux objectifs de l'Approche

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 Conditions favorisant ou entravant la mise en œuvre de la(des) Technologie(s) appliquée(s) sous l'Approche

disponibilité/ accès aux ressources et services financiers
  • entrave

-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:

cadre juridique (régime foncier, droits d'utilisation des terres et de l'eau)
  • favorise

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.

connaissances sur la GDT, accès aux supports techniques
  • entrave

-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.

autre
  • entrave

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. Participation et rôles des parties prenantes impliquées dans l'Approche

3.1 Parties prenantes impliquées dans l'Approche et rôles

  • exploitants locaux des terres / communautés locales

Farmers community

Men were involved more, because of the hard work in the field.. Many people are using the green manure technique to increase the crop yield but no any incentives and support has been provided by government institutions targeting the socially and economically disadvantaged groups.

  • gouvernement local

Hierarchy;District Development comittee-Municipality-VDC

  • gouvernement national (planificateurs, décideurs)

Ministry of agriculture

suivi/ évaluation passive Gradual progress and support from government and institutions.
Research soutien extérieur Research being carried by institutions, on nutrient content and new species of green manure plant.

3.4 Prises de décision pour la sélection de la Technologie/ des Technologies

Indiquez qui a décidé de la sélection de la Technologie/ des Technologies à mettre en œuvre:
  • principalement les exploitants des terres soutenus par des spécialistes de la GDT
Expliquez:

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.

Les exploitants des terres peuvent-ils poursuivre ce qui a été mis en œuvre par le biais de l'Approche (sans soutien extérieur)?
  • oui
Si oui, décrivez de quelle manière:

Since it is easy and natural method to increase the fertility of the soil,farmers can be benifited..it only requires the basic knowledge about the seasons and seeds(improved) so it can be easily implemented.

6.4 Points forts/ avantages de l'Approche

Points forts/ avantages/ possibilités du point de vue de l'exploitant des terres
-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.)
Points forts/ avantages/ possibilités du point de vue du compilateur ou d'une autre personne ressource clé
-Increase the fertility of the soil.
-it can help to increase the biomass in the soil.
-Increases microorganisms and their activity in the soil. (How to sustain/ enhance this strength: They can be enhanced if the present trend of exploiting green manuring plants are changed to develop their production on a sustainable basis.)
