most high biomass crops, jute has a high demand for plant
nutrients, especially of the macronutrients, like nitrogen,
phosphorus and potassium.
crop of tossa jute yielding 3.1 t ha-1 of dry
fibre takes on an average of 65 kg N, 52 kg P2O5
, 163 kg K2O, 128 kg CaO, and 33 kg MgO ha-1.
jute, on the other hand, yielding 2.0 t ha-1 of dry
fibre takes on an average 84 kg nitrogen, 37 kg P2O5,
117 kg K2O, 120 kg CaO, and 49 kg MgO ha-1
during growth period.
The critical limits for soil
available P, S and Zn were worked out as 24 kg P2O5
ha-1, 8.5 ppm SO4-S and 0.5 ppm Zn,
respectively. Nitrogen, however, remains as the main cotributing
nutrient to boost fibre yield. Nearly 18-21 kg extra jute fibre
may be obtained by the application of 1 kg ha-1of S
in S-deficient soils as worked out in India. It has been found
that, on an average, 15 tonnes of green jute leaves per hectare
are added to the soil enriching its fertility level during the
nutrient management is a strategy that incorporates both organic
and inorganic sources to achieve higher yield, and what is more
important, for sustainability in production for the entire
cropping system. Jute is generally succeeded by exhaustive crops
like rice and vegetables often causing gradual process of
decline in soil organic matter content if not approppriately
supplemented through organics in the form of FYM/ crop residues/
biofertilisers, and/ or by inclusion of legume in the cropping
thinning and weeding are generally practised in all jute fields,
which should be best practised under optimum soil moisture
helps uprooting the weeds and thinning for removing excess jute
plants to bring down the population to 30-45 per sq m. Raking
is followed by hand weeding. Small hand-held wheel hoes or
scrappers may also be used for weeding. Usually one raking
between two to three weeks following sowing followed by two to
three weedings at an interval of fifteen to twenty days is done.
With subsequent crop growth and canopy development weed growth
One pre-sowing irrigation
(if necessary) + 2 to 3 additional irrigations at later stages
are recommended for better crop growth and higher yield.
Appropriate drainage facility may be arranged in order to avoid
stagnation of water in the event of high rainfall during the
crop growth period.
