Description
An experiment was conducted on a salt affected soil at farmer’s field to compare different amendments (gypsum, H2SO4, farm yard manure and sand) in various possible combinations in RCBD for assessing their effectiveness on soil reclamation. The soil was dense saline sodic {ECe= 10.24 dS m-1, pHs= 9.57 and SAR= 28.70 (me L-1) 1/2} with clay loam texture. Rice variety Shaheen and wheat variety Inqalab-91 were sown as test crops. Recommended doses of NPK fertilizers were applied to the respective crops. Field was irrigated with tubewell water having ECiw= 0.84 dS m-1, SAR= 8.09 (me L-1) 1/2, RSC= 4.25 meL-1. Reduction of 7% in pH of the soil was observed due to application of 0.1% sand at the end of second year of cropping. The lowest pH was recorded with gypsum and FYM. The same combination of gypsum and FYM reduced the ECe more than the rest of the treatments. Reduction in the SAR was significant with the application of gypsum and H2SO4 in the second year. Sanding alongwith gypsum application significantly enhanced the grain yield in both crops. However, gypsum@ 100% GR added with FYM and gypsum@ 75% and H2SO4 increased the yield for the first year of rice crop. The yield trend of wheat was other way round.
