For the extraction of Sisal and Ramie fibre directly from the harvested leaves/canes, the machine ‘Raspador’ Decorticator was developed, which is powered by 5 H.P motor/engine. The machine is portable and can be taken to the field for its operation. Sisal leaf or Ramie canes are fed in to the machine and manipulated manually to extract fibre. The machine works on the principle of rapid beating and scraping leaves/canes progressively down its length through a rotating drum having beater knives on the periphery. The rotating drum maintains clearance (in which leaves/canes travel) against the base plate for rasping action. It involves two directional feeding actions. A person can extract dry fibre in an hour about 10 kg sisal and 6 kg ramie (contains gum about 25 %). Cost of the machine is about rupees fifty thousand. (Fig. 11)Zoom Image
 

Power operated portable machine was developed to extract green ribbon of jute, Mesta, Sunnhemp and Ramie plants by breaking the stick into small pieces. The machine works on the principle of beating the canes progressively down its length and scrapping when the operator pulls out the canes. It involves two directional feeding actions. The machine is powered by 1 HP motor, weight about 125 kg and feasible to operate in field condition. About 5-6 normal canes can be fed into the machine at a time by a person and per hour ribbon extraction capacity equivalent to dry fibre is about 25, 15, 8 and10 kg Jute, Mesta, Sunnhemp and Ramie respectively. Cost of the machine is about Rs. 16,000/-. (Fig. 10) Zoom Image
 

The power operated CRIJAF FLax Fibre Extractor was developed to extract (scutch) flax fibre. It is portable, powered by 1.0 H.P motor and weigh about 105 kg. Dry retted flax or linseed stalks are fed manually into the machine and scutched fibre is collected by the same person. Fibre extraction could be done by single man/women in standing or sitting posture. The fibre extraction capacity of the machine is about 3-5 kg dry fibre per hour. (Fig. 12) Fig. 7.

The herbicide applicator is a tool to apply non selective herbicides in directed manner in between row crops to control composite weed flora.In broadcast jute, synchronous weeding, thinning and row development is possible (Fig 2) using this tool if operated since 15-20 days of its germination. With the help of this tool nonselective herbicides can be used in field crops, horticultural crops and kitchen garden and 80 to 85 % weeds can be controlled. Rest, 15 to 20 % of the weeds within the rows have to be removed manually. The usual drift hazard from herbicide application is completely eliminated here.Zoom Image
 

It is light in weight (about 50 kg), feasible to operation in field condition by a man/women. Freshly harvested jute plants (5-6 nos) are fed by the tip end to 10-15 cm length in to the machine and after activating ribbon separation unit by pressing foot, the canes are pulled back manually. Green ribbon remains in the hand of the operator while unbroken stick is ejected forward. Green ribbon extraction capacity with this machine is equivalent to about 25 kg dry jute fibre/hour; whereas, by traditional whole plant retting method manual fibre stripping capacity of a person is about 5 kg dry jute fibre per hour.

Manually operated multi-row (4 and 5 rows) seeder has been developed to sow jute seed in line. Seeder is operated by a man/women and sowing capacity is similar to the conventional broadcast about 5-6 hrs/hectare. Seed requirement is 3-4 kg/hectare about half of the broadcast method. Line sown crop favours better inter cultural operations especially weeding. The yield of fibre is comparable to broadcast field although better managed line sown field yields more fibre at the reduced cost. The seeder was commercialized and its cost (for the year 2010) is Rs. 3245 and Rs. 3650 for 4 and 5 rows, respectively.Zoom Image
 

Apply Nail Weeder in broadcast or line sown jute field from 3 to 5 DAE onwards. It controls all types of weeds at the germinating and young stage. It controls upto 80% of field weeds. Rest of the weeds is to be controlled by manual, chemical or other means. In broadcast jute crop its application works simultaneously in three ways-----Weeding, Thinning and Line development. It also works for soil mulching, soil moisture conservation and its draft requirement is low. During operation, nail assembly can be replaced by usual tynes or scrappers for wide range weed control. About 5 man days needed to operate the tool for a hectare of jute field, i.e. 5 man-hour for a bigha of land. It can be use in other field crops and horticultural crops.Zoom Image
 

Manually operated (Push and Pull type) weeder suitable to operate in between rows of jute crop was developed and it is easier to operate by a man/woman. It is light in weight (about 6 kg) and the angle of wooden handle can be adjusted to hold firmly as per the need (height) of the operator. Weeding capacity of the weeder is about 0.045 hectare/hour, which is about 5 to 10 times more than the weeding done with the help of khurpi manually. The cost of the weeder is about Rs. 1400/- . This weeder is also useful in other line sown crops. (Fig. 8)Zoom Image
 

It is animal drawn primary tillage equipment for land preparation, turning the soil so as to increase the soil fertility and control weeds. It consists of main body, blade, saddle, land side, mould board, u-clamp and conduit pipe handle.Zoom Image
 

The Power Tiller is used in dryland conditions with specially designed blades. and energy consuming for many crops.It is a two wheel tractor with a rotary tiller more commonly known as rotavator. The power from the engine is transmitted to the drive wheels and the rotavator through "V" belts, chains and sprockets and gear trains. Because of two wheels, an operator generally has to walk behind the power tiller to guide the direction of travel for various operations. The design of blade for dry rotavation are such that a single rotavation for preparatory tillage can suffice the need for ploughing, harrowing and even planking. After single operation of rotavator, the seed can be sown directly for most crops. This makes the seed bed preparation cheap and less time There are hand clutches to engage and disengage power to the wheels and the rotavator unit.Zoom Image
