Abstract:

Studies on subsurface drainage were carried out on silty clay and clay soils in Gundur village from 2015 to 2016. The mean pH of samples ranged from 8.16 to 8.35 before sowing and 8.21 to 8.41 after harvesting and before sowing the electrical conductivity ranged from 10.92 to 14.65 dS m-1 and 9.28 to 13.68 dS m-1 after harvesting. Similarly, the Ca2++Mg2+ and Na+ values were in the range of 34.01 to 37.14 and 10.47 to 12.89 Meq/100g before sowing of crops, after harvesting of the crops results obtained were in range of 33.34 to 36.92, 10.92 to 12.16 Meq/100g of soil. The ESP values were in the range of 15.11 to 17.74 before sowing and 13.86 to 16.69 after harvesting of crop. A glance at results reveals that pH was observed to be increased due to sodic nature of soil and excess application of the fertilizer. ESP was noticed to be reduced in smaller amount as compared to pre-sowing conditions, gypsum needed to be applied in required amount in order to turn the soil from sodicity to non-sodic soils. Finally, the yield was observed to be increased as 52.50 q ha-1 as compared to pre drainage conditions of 38.50 q ha-1.
