Water
district, Assam were studied. The multi–location soil samples were collected from six
jute–growing blocks, namely Khagorijan, Raha, Rupohi, Dhing, Laowkhowa and
Juria. The soils were acidic in reaction and clay loam in texture. The Soils were enriched
in organic carbon content (1.02% to 1.11%) and medium to marginally high in available
nutrient contents. The characteristics of soil water retention indicated that at any given
suction, the magnitude of water retention follow the order: Rupohi > Raha > Khagorijan >
Dhing > Laowkhow > Juria. Available water capacity among the various soils varied in
between 0.18 m3 m–3 and 0.30 m3 m–3. Wide variations among the soils were observed in
unsaturated hydraulic conductivity K(θ) and water diffusivity D(θ). The K(θ) fluctuated
from 0.12 × 10–11 to 0.33 × 10–3 cm min–1 whereas the soil water diffusivity among the
various blocks varied in between 0.08 × 10–7 and 0.02 × 10–3 cm2 min–1. It is evident in
the present study that the soils of Rupohi, Raha and Khagorijan blocks of Assam had
high moisture retention and available water capacity but low K(θ) and D(θ). In rainfed
condition, raising jute as well as other crops is possible in the soils of Rupohi, Raha and
Khagorijan blocks of Nagaon district if the crop and time of its sowing are properly
selected. Proper moisture conservation practices should be adopted for growing rabi
crop in the soils of Dhing, Laowkhow and Juria blocks of Nagaon district as they had
medium moisture retentivity and available water and relatively high K(θ) and D(θ)
