Impact of Saline Soil Management: Practices on Soil Health and Paddy Cultivation in Mandya, Karnataka

Suma, R. and Savitha C. M.

Abstract

The occurrence of saline soil in paddy cultivating belt of Cauvery command area of Mandya district has decreased the yield substantially which prompted Krishi Vigyan Kendra, Mandya to take up frontline demonstration (FLD) on saline soil management from 2006-07 to 2008-09, in Hemmanahalli village, Maddur taluk, Karnataka. The study revealed that the FLD substantially reclaimed the saline soil by decreasing the pH and EC from 8.34 & 4.67 to 8.15 & 3.23 dS/m respectively over three years. Also, it had substantial influence on organic carbon build up from 0.33 to 0.39 per cent. The grain yield was 35.21q/ha in FLD compared to 28.76 q/ha in farmers’ practice (FP) during 2008-09 which amounts to 22.43 per cent increase. The economic analysis revealed that though the initial cost involved in adoption of FLD was higher compared to farmers practice, the net return gradually increased and farmers could realize benefit of Rs. 1.99 per rupee invested in FLD compared to Rs. 1.7 in FP
