The survey work was carried out in rice growing area of middle Gujarat region to assess the available Si content in rice and find out the relationship of Si content with plant. The silicon content of rice grain collected from the region ranged from 1.20 to 5.99 per cent with an average value of 3.01 per cent, respectively and the rice straw Si content varied from 3.52 to 9.80 per cent with an overall mean of 6.30 per cent of different districts. The total uptake of Si by rice was 88, 114, 87, 91, 73 and 102 kg ha-1 in different districts of middle Gujarat and the uptake of Si was nearly 2 to 45 times more as compared to N, P, K and S uptake by rice. The ratio of silicon and other nutrient contents in rice grain and straw indicated that amongst N, P, K, S and Na, the higher ratio was observed in Si: P indicating lower content of P in comparison with silicon. The correlation of coefficient (r) between Si content in rice and other nutrients indicated that Si content in rice grain and straw was positively correlated with N, P, K, Mn and Cu contents and negatively correlated with Fe content of grain.
