Abstract:

The effects of fertilizer management practices on rice and wheat grain yields, concentrations of micronutrient cations and phytic acid were evaluated in a long term were analyzed. The highest grain yield of rice was recorded under treatment T9 (N120P40K40+Znf+FYM) while that of wheat under treatment T11 (N180P80K40+Znf +FYM). Application of T6 (N120P60K40), T7 (N120P40K40+Znf), T8 (N120P40K40+FYM@5 t/ha), T9 (N120P40K40+Znf+FYM @5 t/ha), T10 (N180P80+Znf) and T13 (N180P80K40+Znf) significantly increased in Zn content of dehusked rice grains by 34.8, 57.2, 38.4, 49.0, 44.0 and 60.1 percent over the control, respectively. Application of T5 (N120K40), T7 (N120P40K40+Znf), T10 (N180P80+Znf) and T13 (N180P80K40+Znf) increased in Fe content of dehusked rice grains significantly by 114.6, 89.9, 135.1 and 65.9 percent over the control, respectively. In wheat crop, application of T2 (N120), T3 (N120P40), T5 (N120K40), T6 (N120P60K40), T10 (N180P80+Znf), T11 (N180P80K40+Znf+FYM), T12 (N150P40K40) and T13 (N180P80K40+Znf) increased in Zn content of wheat grains significantly by 30.3, 19.1, 20.5, 29.5, 35.1, 18.3, 28.7 and 40.3 percent over the control, respectively. Application of T9 (N120P40K40+Znf+FYM @5 t/ha) and T13 (N180P80K40+Znf) increased the content of phytic acid in the dehusked rice grains by 10.0 and 2.0 percent over the control, respectively while application of T3 (N120P40) decreased phytic acid by 12.2 percent in comparison to control. In wheat crop, application of T8 (N120P40K40+FYM) and T12 (N150P40K40) increased the content of phytic acid in the wheat grains by 1.9 and 2.5 percent, respectively and application of T2 (N120) and T6 (N120P60K40) decreased the content of phytic acid by 4.4 and 2.7 percent, respectively in comparison to control.
