A field experiment was conducted on fixed plot during rabi 2000-01 to 2003-04 on medium black calcareous soil (Typic Ustocrepts) with garlic cv. GG-3 to study the effect of potassium (three levels 0, 50 and 75 kg K2O ha-1), and zinc (two levels 0 and 25 kg ZnSO4 ha-1) and FYM (20 t ha-1) in a RBD having three replications. Significantly the highest bulb yield, leaves yield and bulb weight were recorded under application of ZnSO4 @ 25 kg ha-1 with potassium @ 75 kg ha-1. Application of zinc and potassium also significantly increased the uptake of Zn and K by garlic. Available K and Zn progressively increased with increase in levels of respective elements.

Significantly the highest bulb yield, leaves yield and bulb weight were recorded under application of ZnSO4 @ 25 kg ha-1 with potassium @ 75 kg ha-1. Application of zinc and potassium also significantly increased the uptake of Zn and K by garlic. Available K and Zn progressively increased with increase in levels of respective elements.
