EFFECT OF GYPSUM APPLICATION AND LEACHING ON THE RECLAMATION OF SODIC VERTISOL AND CROP PRODUCTION

The field experiment on reclamanation of moderately sodic soil was conducted to study the effect of gypsum levels on soil properties improvement, and growth and yield of maize. The gypsum application@ 75% G.R. followed by adequate leaching gave maximum yield of fodder maize. It was also observed that the amount of salt removal and ESP decreased considerably with the increments in gypsum application rate. The salts of 1359 kg/ha were removed from the soil depth of 90 cm due to gypsum application as per the Schoonover\u27s method
