2.1 Breve descripción de la Tecnología

Definición de la Tecnología:

Planting pits in banana plantation filled with a mixture of manure, organic material and soil, to improve soil moisture and fertility and to enhance crop production and famer's income.

2.2 Descripción detallada de la Tecnología

Descripción:

The planting pits are established between banana stems and filled with organic vegetative material mixed with decomposing manure to form a reservoir of nutrients for a long run. On gentle slopes covered with extensive banana plantations, the planting pits are dug at the center of banana stands. Before estbalishment of this technology, only the composting process was available for the conversion of organic domestic waste into manure. However, compost manure takes slightly longer to produce and is more bulky than conservation troughs making the latter easier to adopt. The technology can be applied to annual cropland as well. Application of the technology improves banana bunch size and plantation yield by over 300%.

Purpose of the Technology: The main objective is to improve soil fertility. The planting pits also check runoff thereby reducing soil erosion, improving moisture infiltration and retention, and enabling the plantation to withstand the dry months. Cabbages, beans and other high value vegetables can be grown directly on top of the trough.

Establishment / maintenance activities and inputs: The planting pits are established using simple tools such as the hand hoe, spade, panga and wheelbarrow. The hoe is used to dig up the soil and soften it. The soil is then scooped out using a spade, to create a bowl-shaped trough. The panga is used to chop the remains of harvested bananas (stems and leaves) which are then, carried to the troughs using a wheel barrow. The planting pit is 0.45 m to 0.60 m deep depending on the amount of manure available and 0.6 m wide. Each trough is about 0.60 m from the nearest banana stand. It is filled with chopped banana stems, followed by a layer of manure and then covered with mulch to prevent excessive evaporation of moisture. The planting pit is then covered with soil. After 3 to 4 months, the vigor of the banana stems improves. If the trough is opened by digging, roots are observed to have grown through the walls of the planting pit from all directions.

During the rainy season, the trough slowly fills with sediment from surface erosion. Weeding at the trough is done by uprooting the weeds using hands or a hand hoe.

Natural / human environment: Over time, the banana stands grow towards the trough. To maintain the distance between the stands, the suckers nearest to the trough are pruned.

3.1 Propósito(s) principal(es) de la Tecnología MST

• mejorar la producción
• reducir, prevenir, restaurar la degradación del suelo
• crear impacto económico benéfico

3.2 Tipo(s) actuales de uso de la tierra donde se aplica la Tecnología

Comentarios:

Major land use problems (compiler’s opinion): The light, sandy loam soil on a hilly slope has very little capacity to hold water. The soils are dry a few days after it rains. The banana plantation therefore suffers two problems: inadequate soil water for plant growth and low nutrient retention. The problem of soil erosion is critical in the area but is addressed more adequately by fanya ju retention trenches stabilized with Napier grass strips.

Major land use problems (land users’ perception): Low productivity of the land compared to past seasons.

4.1 Dibujo técnico de la Tecnología

4.2 Especificaciones técnicas/ explicaciones del dibujo técnico

Conservation troughs (0.4-0.6 m deep) are partially filled with a mixture of manure, undecomposed banana stems and other organic matter to add organic matter into the soil. They also capture rainfall runoff and help to maintain suitable soil moisture. The conservation trough should be dug about 0.6 m from banana plant so that the heat produced during decay does not affect the plant.

Availability of labour and animal manure are the most important factors affecting cost of the establishment activities. To reduce cost of labour it is recommended to apply Farmer Field Schools approach. To reduce cost of manure farmers can produce their own farmyard manure, e.g. by implementing zero-grazing technology.

Comments on acceptance with external material support: It is a farmer initiative and no support has been received for the adoption of this technology.

100% of land user families have adopted the Technology without any external material support

22 land user families have adopted the Technology without any external material support

Comments on spontaneous adoption: This is a farmer field school initiative and the district facilitator for Kagera TAMP (and also an Agricultural officer of the local government) provided guidance on positioning the pits for maximum utility.

There is a strong trend towards spontaneous adoption of the Technology

Comments on adoption trend: Noticing the results in only 3 seasons, the other farmers (not members of farmer field school) are also adopting the technology.

6.7 Fuerzas/ ventajas/ oportunidades de la Tecnología

Fuerzas/ ventajas/ oportunidades desde la perspectiva del compilador o de otra persona de referencia clave
The technology requires the use of only the simplest of farm tools such as a hand hoe, a spade and a wheel barrow. How can they be sustained / enhanced? Dissemination of the the technology through regular community meetings and a local language newsletter
Demonstration of benefits is achieved quite quickly and therefore adoption by farmers is good. How can they be sustained / enhanced? Emphasize technology at farmer field school demonstration plots
Technology bears similar benefits to composting but with a shorter list of activities How can they be sustained / enhanced? Encourage adoption through demonstration
Since the technology utilizes stem cuttings, whole stems are harvested reducing the risk of pests and diseases especially banana bacteria, that would be harbored by exposed rotting stems How can they be sustained / enhanced? Knowledge dissemination through regular community meetings and local language newsletter

6.8 Debilidades/ desventajas/ riesgos de la Tecnología y formas de sobreponerse a ellos

Debilidades/ desventajas/ riesgos desde la perspectiva del compilador o de otra persona de referencia clave	¿Cómo sobreponerse a ellas?
The technology is labor intensive	Farmer Field Schools bring farmers together in a community level effort
The technology requires livestock manure in a predominantly cultivator community	Introduce zero-grazing livestock for manure production
