Mulberry (Morus alba L.) is a deep rooted foliage crop, which is cultivated widely in Assam
for rearing silkworm (Bombyx moriL.). The fertility status of soil on which the mulberry is grown affects
the yield and quality of leaf, which reflects on the quaJity of silk produced. A study was undertaken to
assess the nutrient status of mulberry growing soils in some selected seri-villages of Golaghat district of
Assam. Composite soil samples were collected from the areas under mulberry cultivation at two different
depths namely, 0-20 and 20-50 cm. Results indicated that soil pH varied from 5.0 to 7.6 and 5.3 to 7.6 n
the surface and sub-surface soils, respectively with the corresponding mean values of 6.1 1 and 6.46. Soil
organic carbon (SOC) content ranged from 0.04 to 1 .90%o and 0.02 to 0.7l%o for surface and sub-surface
soils, respectively with the corresponding mean values of 0.58 and0.24%o. Data on available nutrients
indicated that N content varied from 66.5 to 408 and47.5 to 332 kg ha-1 in the surface and sub-surface
soils, respectively; the corresponding values for P (as P2O5) were 3l.2to 87.2 and2l.7 to 80.4 kg ha-1.
Mean content of N and P (as P2Os) in the surface soil.were 250 and 59.3 kg ha-1, respectively; whereas,
the corresponding values for the sub-surface soil were 174 and47.4kgha-1. Similarly, higher K content
was also observed in the surface soil as compared to sub-surface soil. Data showedthat 68.2% of the soils
were low in N, whereas 3l.8o/o of the soils were in medium category. In case of P, about 13.2, 5l.l and
35.7% of the samples were categorized under low, medium and high, respectively. The percentage of
samples categorized under low, medium and high in case of K was 14.0,48.2 and37.8o/o, respectively.
Micronutrient status also indicated higher content of Zn, Cu, Fe, Mn and B in the surface soil as con.]pared to sub-surface soil. About 48.2% of the soil samples were deficient in available Zn. However,
no def-rciencl' of Cu, Fe and Mn was observed. About 51.2% of the samples were marginal in B status.
Significant positive conelation rvas obtained between nutrient content and organic carbon. However,
significant negative correlation was found between nutrient content and soil pH. The study indicates that
appropriate nutrient management is required in respect of N, P, K, Zn and B in soils under mulberry land
use in Golaghat district of Assam.
