2.1 Descrição curta da tecnologia

Definição da tecnologia:

Restoring banana production through temporal crop substitution and the use of SLM and recommended husbandry practices in controlling the deadly BXW disease.

2.2 Descrição detalhada da tecnologia

Descrição:

This conservation measure is used in BXW epidemically affected areas. Land users in affected areas are trained on the principle behind the diseases and means and ways to overcome it. Banana plants in seriously affected farms are uprooted and destroyed and non disease host crops usually maize and common beans are grown for starvation and destruction of BXW pathogen. The land is not used for banana production for a period of 6 months and instead substitute crops ensures food and income security to land users. Leguminous cover crops (beans) and crop residual management skills applied on the farm revitalize the soil health in terms of biomass, moisture and nutrient recycling. After 6 months, banana production is resumed where production is based on recommended husbandry practices combined with SLM conservation measures. The use of certified banana cultivars, optimal plant geometry and disease control cultural practices are some of the basic recommendation. Certified banana cultivars are planted at a space of 3m x 3m. The size of a hole used to plant banana is 0.9x0.9 m wide and 0.6 deep. During digging top soil is separated from subsoil. 2 -3 tins of manure are mixed with the top soil and the mixture is put in the bottom of the hole. The holes are left for microbial decay to take place and banana planting is done after 1 or 2 months. The tied Fanya chini water retention ditches are water harvesting and conserving structures constructed by digging trenches along the contour where dug soil is thrown to the lower side to form an embankment that prevents soil from falling back in. A-FRAME method is used to mark a contour line and on the other hand ARM OUTSTRETCHED LEVEL method determines how far apart the Fanya chini retention ditch should be. Unlike other retention ditches, the dug ditches are not continuous but instead are tied at regular interval with small cross–ties of 0.4-0.6m length. Ties intercept the ditch at right angle to form a series of narrow rectangular segments of infiltration ditches each of 5 meters long, 0.6m wide and 0.6m deep arranged in series within a contour line. Ties helps to prevent irregular flow of runoff and to ensure an evenly distribution of captured water. Fanya chini embankments are stabilized by planting crops on them the common crops are pigeon pea (space used between plant is stand is 1m x 1m), lemon grass (30cm x 30cm) or pineapples (60cm x 60cm). Mulching is done using grasses. The dominant grass species used is Hyperrenia rufa where a mulching depth of 15 cm is used.

Purpose of the Technology: PURPOSE: Improved food and fodder productivity, soil moisture and water holding capacity, nutrient recycling, and organic matter content, biomass cycle, crop tolerance to drought, income and food security, poverty reduction and health. Prevent unproductive evaporation of green water, combating soil erosion by water runoff and biological degradation due the deadly BXW disease.

Establishment / maintenance activities and inputs: ESTABLISHMENT: procurement and mobilization of working tools, uprooting and destruction of infected plants in affected fields, land tilling and harrowing, planting of alternative crops or creation of a productive disease free buffer zone, temporal harvesting of maize and beans, land preparation/ demarcation and spacing of holes for resumed banana planting, digging holes, manure application before planting, banana planting, demarcation of contour line for construction of Fanyachini contours with ties, digging and construction of Fanya chini contours with ties, vegetative stabilization of Fanya chini bunds (using lemon grass, pineapples or pigeon pea), random planting of castor oil plants for future anchoring support of plants with heavy bunches and mulching application. MAINTENANCE: hand weeding to control noxious weeds combined with other pest and disease control (control of nematodes and weevils), de-suckering to leave the mother plant and two baby plants, de-trashing or trimming of unproductive leaves, regular removal/de-bud of inflorescence (male bud) using a forked wooden pole once the bunch is completed to prevent BXW transition through insect vector , recurrent manure application, removal of sediments and maintenance of Fanyachini bunds, harvest of bananas, maize, pineapples and pigeon pea. INPUTS USED: largely includes labour (strenuously varying from light, medium and heavy), tools (hand hoe, forked hole, machetes, sickles, spade, mattock and A-frame), seedlings; improved or certified banana varieties, pineapples suckers, lemon grass and castor oil, seeds (beans, maize and pigeon pea), farm yard manure and mulching materials (preferably Hyperennial spps).

Natural / human environment: NATURAL ENV: The land use type is cropland with annual, perennial and some fruit tree crops. The technology involves a combination of agronomic, vegetative, structural and management conservation measures. Management measure involves all activities related to temporal shift to alternative crops for making the farm disease hot free and for staving and destroying the disease pathogen. Climatic zone is sub-humid with an average of 210 days of growing period (LGP). Average slope category is gentle lying between 2-5%. A soil texture class is sandy loam with medium depth categories. HUMAN ENV: the level of mechanization is hand tools. Production system is mixed (both subsistence and market or commercial oriented). The average costs of inputs required is 3015.68 USD. Land ownership is largely individual not titled and partly communal.

Pontos fracos/desvantagens/riscos na visão do usuário da terra	Como eles podem ser superados?
Good and attractive crops that consumers are willing to purchase at a high price have resulted to emergence of thieving.	Spread the technology and supply improved banana suckers to other farmers so that more farmers are engaged in banana production. Strengthen community police.
The technology initially is labour and capital intensive	Encourage group working spirit.
Unplanned Changes of service providers which may fall in the hands of untrustworthy service providers.	Pluralism in service delivery should be planned with doubly consciousness to take care of untrustworthy service providers.
