A fertilizer trial was carried out in old Brahmaputra floodplain soil with a view to examine the effect of Zn, B, S and Mg on the growth and yield of potato (cv. diamant). The elements were added in 15 (fifteen) possible combinations along with a control. The rate of Zn, B, S and Mg were 9.0, 1.1, 12.6 and 6.5 kg/ha, respectively. The treatment receiving Zn, B, S and Mg together gave the highest tuber yield (30.90 t/ha) and the lowest yield (25.40 t/ha) was obtained in control treatment. Assessing the contribution of individual elements, S alone had a marked influence on crop yield and resulted in 6.30% yield increase over control as against the yield increment of 21.65% by the combined treatment of Zn, B, S and Mg. The yield contributing characters showed a similar trend. Thus for efficient potato production in this soil, application of S is essential and further, the addition of B and Mg to this soil may substantiate the yield to some extent. The soil does not require Zn supplement for potato
