Abstract
The survey work was carried out in paddy growing areas of
Ahmedabad, Kheda, Anand, Vadodara, Panchamahals and Dahod
districts of middle Gujarat region in the month of October-November
2009 to assess the available Si status in paddy soils and find out the
relationship of silicon content with soil and plant properties.. Twenty
representative surface soil and plant samples from each district
were collected from different rice ecosystem of the region. Thus, a
total of 120 surface soil and 120 plant samples were collected from
different villages of six districts. Available silicon in soils determined
by NaOAc buffer method and plant samples was analysed for Si, N,
P, K, S, Na and micronutrients (Fe, Mn, Zn and Cu) contents. The
coefficient of correlation (r) was worked out to know the relationship
between available Si and soil properties and silicon content and
uptake by paddy.
