One variety each in of Tossa jute (C. olitorius) & white jute (C. capsularis) viz., AAUOJ 1 (Tarun) and AAUCJ 1 (Apeswaree) developed by the AINP (Jute & Allied Fibres) centre in Assam Agricultural University at Nagaon have been released by CVRC & SVRC, respectively. Despite, one variety of ramie namely, R-1411 (Hazarika) developed at Ramie Research Station, Sorbhog has been identified during last AINP Workshop held at CRIJAF, Barrackpore.
c) Disease/ pest problem
Jute: Semilooper, Bihar hairy caterpillar, yellow mite and stem weevil indigo caterpillar and grey weevil are the important insect pests of jute. Recently mealy bug has been recorded to infest jute.
Stem rot, root rot, anthracnose and seedling blight are the common diseases on jute.
Ramie: Cercospora leaf spot disease, leaf roller (Sylepta derogata), Indian red admiral caterpillar (Vanessa indica Hurbst.) and leaf eating caterpillar (Spodoptera exigua) are the important insect pests and diseases affecting ramie crop at different stages of crop growth.

Crop protection Fenazaquin 10 EC or fenpyrozimnate 5EC @ 2 ml/lit may be sprayed at 30 and 60 DAS for effective management of yellow mite. In the later stage of crop the lepidopteran pests can be controlled by foliar spray of profenophos ( 0.1%) at 10 days interval.
For managing stem rot and anthracnose of jute and foot and stem rot of mesta, seed treatment with carbendazim @ 3g/kg seed and 2-3 spraying of carbendazim (0.2%) or Copper oxychloride (0.3%) can be applied.
Stage of harvesting
120 days after harvesting
Retting Proper retting and extraction of fibre (after 12-15 days of jaking) should be done in clear and slowly flowing water for quality fibre. CRIJAF microbial consortium mediated retting improves the quality and reduces the retting time by 7 days.
Ramie Variety /Cultural practices
Details
Land preparation
2-3 deep ploughing followed by laddering Variety R-67-34 (Kanai) and R 1411 (Hazarika)
Time of
planting
For North-Eastern states –
Rainfed condition : February – March / April & end September – October Irrigated condition : Throughout the year except winter; during peak rainfall planting can be done only if adequate drainage is provided
Method of planting &
spacing
With newly developed planting technique using furrow opener; 60 cm (row- row) x 30 cm (plant-plant) at 5 cms depth
Seed rate i) Rhizome planting : 8-10 quintal / ha
ii) Plantlets/stem cutting : 55000 – 60000/ha (including 10% mortality) Nutrient
management
N:P2O5:K2O – 30:15:15 kg/ha/cutting ; 10-15 t/ha of organic matter to be added at beginning of every year
Weed management
Quizalofop ethyl 5% E.C. @ 60-90 g a.i./ha 15 days after emergence effectively control grassy weeds
Crop Protection Disease control : spraying of propiconazole or difenconazole @ 0.1% or mancozeb @ 0.25% 15 days after previous harvest for management of foliar diseases
insect pests and termite control: spraying of chlorpyriphos @ 0.05% at 15 days intervals
Harvesting Under rainfed condition, usually 4 cuts may be taken in a year at 50, 45, 45 and 50 days interval respectively. Under irrigated condition 5 cuts can be
117
taken. Harvesting is done manually by cutting the stalks manually near ground level.
Decortication Fibre is extracted from harvested defoliated canes by a decorticator machine.
It is a 5 HP machine run by diesel or electricity. Around 800 – 1000 kg cane can be decorticated everyday by this machine which produces approximately 35 to 45 kg fibre. The raw fibre is then washed thoroughly in clean water to remove some of its gum and then sun dried for 2 to 3 days.
Degumming The decorticated ramie fibre contains a large amount (19–30%) of gummy matter. According to the chemical degumming method developed at NIRJAFT, decorticated fiber is boiled in 1% caustic alkali solution with liquor ratio 1:6 or 1:7 containing some wetting agent at 96-98oC for two hours in a digester under pressure. Treatment of fibre with of 0.5% sodium sulphite treatment improves tenacity of the fibre. The excess alkalinity is neutralized by treating with 6% acetic acid. The resultant fibre is creamy yellow in colour and is bleached with 6% H2O2 or sodium hypochlorite solution, to make the colour milky white with gum content.
e) Seed production report
Seeds of the newly released and notified olitorius jute var. ‘Tarun’ developed by the centre are produced at various research stations and KVKs of AAU. The Govt. of Assam has been procuring Breeder and Foundation seeds of ‘Tarun’ from AAU for their seed production programme. The Government of Assam has taken a massive seed production programme of this variety, ‘Tarun’ in different districts. Likewise a seed production programme is taken by AAU for the newly recommended high yielding capsularis jute variety, ‘Apeswaree’ (AAUCJ 1) developed by the centre, recommended by Assam State Seed Subcommittee.
