ABSTRACT
A field experiment was conducted using maize as a test crop at Zonal Agricultural Research Station, Navile, Shivamogga, Karnataka. The experiment consists of seven treatments with four replications using lime sludge, agricultural lime and calcium silicate as the source of liming materials at 45 and 50 per cent calcium saturation levels. The results indicated that liming significantly improves the soil pH, CEC, exchangeable and available nutrient status. Application of calcium silicate @ 45 per cent calcium saturation level increased the both grain (69.75 q ha-1) and stover yield (64.15 q ha-1) of maize over control (50.90 and 41.75 q ha-1 of grain and stover yield respectively) followed by lime sludge and agricultural lime.
Key words :
Calcium saturation, Liming materials, Soil chemical properties, Yield of maize, Zea mays.
