Effect of mixtalol at different levels of nitrogen on grain yield of rice

Abstract

Field experiments were conducted in 1988 aus and T. Aman seasons and 1989 boro season to observe the effects of Mixtalol at three levels of nitrogen on grain yield of rice. Application of Mixtalol had no significant effect on grain yield of rice during aus and T. Aman season but it increased the grain yield In the boro season. Mixtalol at 2 ppm a.i./ha produced the highest grain yield of 3.59 t/ha which was 17% higher than the control (no Mixtalol application). Spraying of Mixtalol at 5 ppm a.i/ha gave 14% higher grain yield than the control. The interaction of Mixtalol and nitrogen had no significant effect on rice yield.
