Abstract
Graded levels of N (0,50,100 and 150 kg ha¹), P(0,25,50 and 75 kg ha¹) and K(0,25,50 and 75 kg ha¹) in selected combinations were tried as treatments besides application of zinc sulphate in the soil at 12.5 and 25 kg ha" and foliar spray at 0.5% in fractional factorial design. The two year results revealed that increased doses of application of N,P and K increased the garlic bulb yield and also the uptake of the respective nutrients. Graded levels of the major nutrients also increased the available nutrient content in the soil. A judicious combination of 100-75-50 kg NPK ha and soil application of 100-75-50 kg NPK ha and soil application of ZnSO4 at 25 kg ha' was found to be the optimum to get high yield (upto 20% ), nutrient uptake by the crop besides maintaining the soil fertility in terms of availables major nutrient contents under the conditions of acidic leteritic soils of Kodaikanal
