Two different field experiments were conducted for two years during 1985-86 and 1986-87 to study the relationship of Mn (0, 15 and 30 kg ha-1) with Fe (0, 15 and 30 kg ha-1) and Zn (0, 10 and 20 kg ha-1) under two fertility (NPK) conditions on yield and quality of opium poppy. The main effect of these micronutrients with respect to latex yield was highest at 15 kg ha-1 of Mn or Fe and 10 kg ha-1 Zn. Increasing the level beyond that resulted in reduction in latex yield. Highest response was observed when 15 kg ha-1 Mn was applied with either 15 kg ha-1 Fe or 10 kg ha-1 Zn. Morphine, codeine, narcotine and thebaine content of the latex was highest with 15 kg Mn, 15 kg Fe or 10 kg ha-1 Zn or the combined application of 15 kg Mn with 15 kg Fe or 10 kg Zn ha-1.
